Transfer files from Android to Ubuntu 15.10 Lenovo G50-45 Laptop using Bluetooth.

I struggled to use Blue-tooth on my Ubuntu 14.04 Lenovo G50-45 and eagerly waiting for Ubuntu 15.10 which has Linux Kernel 4.2 and proper drivers for using Blue-tooth on this Laptop. As soon as Ubuntu 15.10 Development version Kernel was upgraded to 4.2 I installed it and happily using it. Although the Laptop got connected through Blue-tooth to my Android Phone I had to try various things including  obex-data-server etc. to transfer the files.

On 22nd Oct 2015 final version of Ubuntu 15.10 was available I downloaded the ISO and made a USB stick and decided to connect Android phone to the laptop using Blue-tooth on Live Ubuntu 15.10.

I had to install Bluetooth Manager to transfer files to and from Android Phone to the laptop.

Importing ICICI Bank, other Banks and Android Applicaton Transactions in GnuCash.

I posted about the same topic in 2011. I have decided to maintain the Books of Accounts on my own in the Current Financial Year 2015-16 (since the tryst with Steam Turbine is temporarily suspended and tryst with Linux is on which the readers of this Blog would have noticed anyway looking at frequency of my posts). I installed GnuCash 2.6.6 on Ubuntu through Software Centre couple of days ago and started importing the Bank Account Files. ICICI Bank no longer offers QIF/MSMoney Fomat download as stated in comments on the year 2011 post. No problem for me. I downloaded the Excel File and saved as CSV which was accepted by GnuCash in the option "Import Transactions from CSV".

I imported the transactions from Bank Accounts, Credit Card Accounts and the corresponding debit/credit entry went into Imbalance and only task then was to change the imbalance into the correct account.

I have again become my own CA, thanks to GnuCash.

I also installed GnuCash Application on Android Phone, created Expenses Account, entered the Cash transactions while shopping, exported the transactions in QIF File, imported that File on Desktop Application and the Transactions are entered there. Great going.

Filing Income Tax Return using Java Utility on Ubuntu.

My CA audits my accounts and sends me the XML file of Income Tax Return for uploading it to Income Tax Return e-Filing site. I check the XML file by opening it in the Browser or if I see that a thorough check is necessary I use other tools including Excel Utility for which I need Windows.

This year I decided to use the Java Utility available in Downloads section of e-Filing site. When I opened it typing ./ITR.sh in the Terminal it produced an error. On Googling I found that I need an older version of Java to use it.

I went to Java Oracle site and downloaded the old version jre-8u51-linux-x64.tar.gz and extracted it to /opt/jre (I had to create the directory). Since the latest version of JRE openjdk-8-jre 8u66-b01-5 was installed on my Laptop I removed it and had to use "G Alternatives" to add the path /opt/jre/1.8.0_51/bin/java for Oracle Java.

I could then use the utility by typing ./ITR.sh in the Terminal and open the XML File to view the Income Tax Return.

I made necessary changes in the Return after consulting my CA and could submit it directly through the utility without logging to e-Filing site.

My Karbonn Sparkle V Androidone received Marshmallow 6.0 update

After formatting the SDCard I could move some applications to SDCard.

Upgrading Windows 8.1 to Windows 10 my experience.

Although this is Linux Blog I have decided to write about my upgrade experience from Windows 8.1 to Windows 10.

My LenovoG50-45 came with pre-installed Windows 8.1. I had disabled Automatic Update on Windows 8.1 and use to update once in a while. When MS decided to give free upgrade to Windows 10 I went through the procedure which asked for applying all pending updates to Windows 8.1 to see Get Windows 10 application. When I clicked on the application it asked to wait for my turn. Becoming restless I searched for how to get immediate upgrade and enabled something which did not work. Finally I got permission to download on Get Windows 10 application and started download of about 2.8 GB. After download got finished something happened during preparation to install and it started the download of 2.8 GB once again.

Getting frustrated I decided to re-install Windows 8.1 through one-key recovery. While booting in re-installed Windows 8.1 MS asked whether I was interested in upgrade to Windows 10 and I said yes to it.

Windows 8.1 re-install damaged Grub2 which I corrected using Boot-repair.

After couple of updates to Windows 8.1 (not all) Windows 10 download appeared on Windows update and I finished the download in 6 hrs (I have 1 Mbps connection).

After finishing download it changed to "preparing to install" and I had to wait patiently for this activity since Windows extracts the 2.8 GB file in the background.

Finally it was ready to upgrade after accepting EULA. The upgrade took lot of time and there were three reboots. On the last boot Windows asked several questions and the best one was to go for express install which I declined and chose "Custom".

After booting to the Desktop Windows 10 did not allow to disable automatic updates but I searched in Wi-Fi Settings to declare my connection "metered" which prevented the automatic update.

Fortunately Windows 10 upgrade did not touch grub2 and I could boot to Ubuntu 14.04.3.

From Ubuntu 14.04.3 Grub2 I could not boot Ubuntu 15.10 using systemd and had to use upstart option. I used Boot-repair once again on installed Ubuntu 15.10 to re-install Grub2.

Finally I have Windows 10/Ubuntu 14.04.3 LTS/Ubuntu 15.10/android-x86 multi-boot successfully working on my laptop.

Running Android 5.1 lollipop on my Laptop.

Recently I came to know that you are able to run android-x86 on PC and Laptop. I downloaded the stable version of Android 4.4 Kitkat and tried it but it did not boot to GUI and presented Root Terminal. Then I did some debugging and came to know that for the AMD APU with radeon R2 on my Laptop I should try a test build of Android 5.1 Lollipop.

I am now running live session of Android 5.1 on my Laptop and posting this on Chrome Browser. I could not take a screenshot now in this session but I will post it later.

I downloaded a recent test build and could install it on hard disk on ext4 partition and added following menuentry in grub2 to boot it:

 menuentry 'Android-x86 5.1 on sdaX' --class android-x86 {
    set root='(hd0,gptX)'
    linux /android-2015-08-16/kernel root=/dev/ram0 androidboot.hardware=android_x86 quiet SRC=/android-2015-08-16 DATA=/android-2015-08-16/data
    initrd /android-2015-08-16/initrd.img
}

 I could take screenshot by pressing PrtSc key.

Happily running Ubuntu 15.10 Wily Werewolf on my Lenovo G50-45.

Update on 21/04/2016: Now more happy running Ubuntu 16.04

I purchased Lenovo G50-45 Laptop in December 2014 and installed Ubuntu 14.04 in dual boot with pre-installed Windows 8.1 as per this post.

When you install any Linux Distribution on a new Hardware it works but not 100% and there were following problems:
1. Screen brightness could not be adjusted.
2. Wifi was erratic.
3. Bluetooth did not work.

Screen Brightness worked after installing Realtek Proprietary Driver but it broke on update in April 2015. I removed the Proprietary Driver and upgraded to Kernel 3.16 through Hardware Enablement Stack which installed the Open Source radeon driver and problem 1 was solved.

Wifi problem was solved creating /etc/modprobe.d/rtl8723be file as follows:

 echo "options rtl8723be fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf

 For Bluetooth I had to wait till Ubuntu 14.04.3 was launched with Kernel 3.19 and it worked sometimes but not on every boot (I wonder why?) after adding following ppa and the driver:

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtl8723au-bt-dkms rtlwifi-new-dkms linux-firmware

On questioning I came to know that I had to wait for Linux Kernel 4.2 when Realtek drivers are included.

On 9th Sep 2015 I came to know that Linux Kernel 4.2 was included in Ubuntu 15.10 and I downloaded the ISO and tried it on my Laptop as per this post. I updated the ISO for couple of days through zsync and it was booting properly every day.

Yesterday I decided to install Ubuntu 15.10 on my hard drive and found that installer crashed, however, I used the following workaround to run the installer and installed:

sudo -H bash -c 'ubiquity gtk_ui'

I am happy to report that there is no need to add any rtl8723be file for wifi, radeon driver is perfect and Bluetooth is working on installed Wily Werewolf.

Booting daily-live/current wily-desktop-amd64.iso from Grub2 and updating it using zsync.

Yesterday I downloaded Ubuntu 15.10 Wily Werewolf Live ISO

wget -c http://cdimage.ubuntu.com/daily-live/current/wily-desktop-amd64.iso

 and used it booting from Grub2 menu entry as follows:

sudo gedit /etc/grub.d/40_custom

and added the following lines:

menuentry "Wily Desktop iso" {
        set isofile="/home/user/wily-desktop-amd64.iso"
        loopback loop (hd0,X)$isofile
        linux (loop)/casper/vmlinuz.efi boot=casper iso-scan/filename=$isofile noprompt noeject
        initrd (loop)/casper/initrd.lz
}

then I updated grub to add the menuentry:

sudo update-grub

I could boot from the ISO and found that Wily has Linux Kernel 4.2 which has Blue tooth driver for my Laptop and it worked well.

Today I decided to keep the ISO updated and installed zsync and used it to update.

sudo apt-get install zsync -y
zsync http://cdimage.ubuntu.com/daily-live/current/wily-desktop-amd64.iso.zsync

File sharing via Bluetooth between Lenovo G50-45 Ubuntu Laptop and Android device.

I had installed Ubuntu 14.04 on Lenovo G50-45 Laptop as per this post in December 2014 and solved some problems like screen brightness as reported in this post after enabling LTS/HardwareEnablementStack.

This Laptop has Realtek Wireless Network Adoptor which also works as Bluetooth device. Although the Wireless disconnection problem was solved by setting options rtl8723be fwlps=0 in /etc/modprobe.d/rtl8723be.conf file the Bluetooth did not work.

After Ubuntu 14.04.3 update I got Linux Kernel 3.19 and the Bluetooth could be used after installing the driver as follows:

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtl8723au-bt-dkms rtlwifi-new-dkms linux-firmware

I could send file via Bluetooth from the Laptop to Android Device but Android device failed to send the file. This could be corrected after searching for Personal File Sharing on Dash and checking the boxes Receive the files in download folder over Bluetooth and Notify about received files.

Mate Desktop 1.10.2 on Debian Testing.

As written in this post I installed Mate Desktop version 1.8.1 on Debian 8.1 and got hooked to it.

In order to run the latest version I edited the /etc/apt/sources.list file and replaced "jessie" by "stretch". Stretch is the codename of next stable version of Debian which is under testing.

After pointing the sources.list to "stretch" I did apt-get update && upgrade && dist-upgrade.

Debian Stretch with linux kernel 4.1.0 is running fine on Mate Desktop 1.10.2

Ubuntu Phone Emulator on Ubuntu 14.04.3.

When I herd about launch of BQ Aquaris Ubuntu Phone in India and its availability by Aug 2015 end on snapdeal I decided to try the Phone in emulator on Ubuntu 14.04.3 on my Laptop.

Since the emulator was launched in Jan 2015 most of the instructions I got to install the emulator did not work. Finally I installed Ubuntu SDK through PPA as follows:

sudo add-apt-repository ppa:ubuntu-sdk-team/ppa

sudo apt update && sudo apt install ubuntu-sdk

Then I installed the emulator through the sdk.

Since running emulator required memory I switched to gnome-fallback session and started the emulator through following command:

ubuntu-emulator run ubuntutouch --scale=0.5 --memory=1024

After waiting for 15 minutes I got the login screen:

I added some applications through Ubuntu Store and could use them.

Running facebook below:

Playing H-265 Videos on Ubuntu 14.04.

While installing Ubuntu 14.04 if you check for installation of proprietary codecs  most videos could be played on Videos application but those having H-265 won't play. For playing them you need to install gstreamer1.0-libde265 as follows.
Open a terminal:

sudo add-apt-repository ppa:strukturag/libde265
sudo apt-get update
sudo apt-get install gstreamer1.0-libde265

Enjoy!

Using antiX live usb on Lenovo Ideapad S100.

I am presently at Bhopal and the family has Lenovo Ideapad S100 Netbook with Windows 7. I had made usb stick with latest antiX-15 which I decided to try on this netbook.

On this Netbook pressing F12 on boot is supposed to bring Boot Menu but it did not work (may be because F12 is actually Fn+F11 and Fn key may not be working on boot).

Pressing F2 however brings the BIOS Set up. In BIOS Set up Boot Tag I could see the USB Stick but there is no provision to bring it up and make it first boot device.

But I could disable booting from Hard Disk (first boot device) by putting a "x" by pressing "x" key and save settings.

Then I could boot from USB and  now posting this on Iceweasel (Open Source Firefox) on antiX-15.

This machine has 2 GB RAM and antiX is very fast.

Review of antiX-15 USB persist on UEFI Secure Boot.

On 30th June 2015 new version of antiX called antiX-15 (Killah P) was released. I was impressed with the announcement "Want to run live on a box with UEFI bootloader? antiX can do this", and immediately wanted to test this.

I downloaded antiX-15-V_64-full.iso from souceforge. The announcement recommended Unetbbotin to make live usb but unfortunately Unetbootin crashed while selecting the iso file. I used dd command to copy the iso to usb but it allowed me to boot only in Legacy mode of BIOS.

I posted on antiX Forum and was advised to mount the iso and simply copy the contents (same like what I recommend for Ubuntu 14.04 for UEFI)

sudo mkdir -p /mnt/iso
sudo mount -o loop,ro  antiX-15-V_64-full.iso /mnt/iso
cp -a /mnt/iso/. /media/USB_mount_point/

 After selecting boot from usb in BIOS Boot Menu I could boot into antiX default Desktop with secure boot on since antiX has Microsoft signed kernel image.

Then I wanted to make the usb persistent. I used the cheat-code "persist=root!,home" in grub boot line but was getting blank screen.

I created the rootfs and homefs files and placed them in /antiX folder on usb even then it did not work:

dd if=/dev/zero of=rootfs bs=1M count=0 seek=1024
mkfs.ext4 -q -m 0 -O ^has_journal -F rootfs
dd if=/dev/zero of=homefs bs=1M count=0 seek=1024
mkfs.ext4 -q -m 0 -O ^has_journal -F homefs 

After struggling for a day I was told to change "gfxpayload=text" to "gfxpayload=keep" in grub.cfg and it worked.

Enjoying old Desktop days with Mate DE 1.8.1 on Debian 8.1

I recently installed Debian 8.1 in triple/quadruple boot with Windows8.1/Ubuntu14.04.2/Ubuntu15.04 on my Lenovo G50-45 Laptop.

Initially I installed LXDE Desktop but yesterday added Mate Desktop and now enjoying good old days of Gnome 2.

How to make back-light Brightness Fn keys work on LXDE.

Back-light Brightness is set on my Laptop by Fn+F11 (down) and Fn+F12 (up) keys. These keys worked on Ubuntu Unity Desktop but not on LXDE Desktop.

I tried xbacklight command but it did not work. Then after googling I discovered that xbacklight does not work on radeon driver.

Then I tried how it works on Ubuntu Unity Desktop and found that following command was executed by USER=root

/usr/lib/unity-settings-daemon/usd-backlight-helper --set-brightness 24

Since the command to be executed required root privileges I created two bash shell files on my desktop:File ~/home/Desktop/Brightness1

#! /bin/bash
# script to set the initial brightness on login
[ "$UID" -eq 0 ] || exec gksu bash "$0" "$@"
/usr/lib/unity-settings-daemon/usd-backlight-helper --set-brightness 12

File ~/home/Desktop/Brightness2

#! /bin/bash
# script to set the initial brightness on login
[ "$UID" -eq 0 ] || exec gksu bash "$0" "$@"
/usr/lib/unity-settings-daemon/usd-backlight-helper --set-brightness 24

I made the files executable and tested them. The script asked for sudo password and set the required brightness.

Then I inserted following Keycodes in ~/.config/openbox/rc.xml

<!-- Keybindings for LCD Backlight -->    <keybind key="XF86MonBrightnessDown">        # decrease screen brightness      <action name="Execute"><command>/home/user/Desktop/Brightness1</command></action>    </keybind>    <keybind key="XF86MonBrightnessUp">        # increase screen brightness      <action name="Execute"><command>/home/user/Desktop/Brightness2</command></action>    </keybind>

and it works by pressing Fn+F11 and Fn+F12 i.e. it asks for sudo password and sets the required brightness. 

How to run Debian with secure boot on.

I am having Lenovo G50-45 Laptop which had Windows 8.1 pre installed and I have installed Ubuntu 14.04 and 15.04 in triple boot with secure boot on.

Today I installed Debian 8.1 on another partition. For installing Debian I had to disable secure boot. After installation if I was booting Debian through its Boot Loader I had to disable the secure boot.

Later on I enabled secure boot and using Ubuntu 15.04 and updated the kernel. After update the grub got updated and it picked up the entry of Debian.

Now I could boot Debian through Ubuntu's Boot Loader without disabling secure boot.

NB: For those who are not familiar with UEFI. Each operating system has its own Boot Loader with entries of other operating systems in the Grub Menu.

Chromixium OS -- Chromebox plus Ubuntu.

I was always fascinated with any OS from Google or something like that. I had tried gOS Desktop in 2007 and Chromium OS on pendrive in 2009.

Google then launched Chrome OS only on Chromeboxes and they have significant market share today.

One developer has combined Ubuntu with Openbox, LXPanel and Google Applications to develops what he calls Chromixium OS.

I downloaded the Chromixium 64 Bit RC ISO, copied it to USB, added casper-rw file and persistent boot parameter in /boot/grub/grub.cfg before "quiet splash" in the menu entry and running it now on my Lenovo G50-45 Laptop. The OS has beautiful Desktop:

How to recover lost Grub Menu and Edit Menu entries.

Yesterday I installed Ubuntu 15.04 on USB stick and selected grub install on the USB to keep the Grub on Hard Disk intact. Even then I lost the Grub Menu on the Hard Disk and had to use the grub on the USB to boot into Ubuntu 14.04.2 installed on the hard disk.

For recovering Grub of menu I had to install Boot Repair through the ppa. After running Recommended Repair through Boot Repair I got the Grub Menu on the hard disk but with many unnecessary entries.

For removing the unwanted entries on Grub Menu I installed Grub Customizer and used it to remove the entries.

Boot Repair and Grub Customizer are excellent tools.

UEFI Bootable full install of Ubuntu 15.04 on 32 GB USB stick.

Yesterday I posted about Live persistent UEFI Bootable USB stick of Ubuntu 15.04. I could upgrade some packages, save wifi settings and documents and they were available on reboot but when I upgraded linux kernel I could not reboot on using persistent kernel boot parameter and even without this parameter.

Since the 32 GB USB stick could take full install I made full install of Ubuntu 15.04 on the stick with installing bootloader on the stick. The bootloader also picked the Windows 8.1 and Ubuntu 14.04.2 installations on the hard disk.

I think the days of persistent live linux on USB stick are over and full install is the way forward.

Live persistent UEFI Bootable USB stick of Ubuntu 15.04.

I had purchased one 32 GB USB stick to back up Windows 8.1 installation on my Lenovo G50-45 Laptop before installing Ubuntu 14.04 in dual boot. Since the dual boot is working well and Windows recovery partition already exists on the Laptop I decided to have Live persistent Ubuntu 15.04 on the stick.

I created 2 GB Fat32 partition, 4 GB ext4 partition with label casper-rw and another 4 GB ext4 home-rw partition on the USB stick. Then I used start up disk creator to put Ubuntu 15.04 on Fat32 partition.

After booting I found that persistence did not work on UEFI machines since there was a bug in live usb creator. The work around was to edit the /boot/grub/grub.cfg file and put "persistent" before "quiet splash" in the menuentry.

Now my wifi settings and documents are avaiable on reboot.

I will try updating the system later on. Upgrades to packages like Firefox worked but when I upgraded the linux kernel I could not boot with or even without persistent boot parameter.

Today I made full install of Ubuntu 15.04 on the USB stick.

My Karbonn Sparkle V Androidone received Lollipop 5.1.1 update.

We bought Google Chromecast.

After buying latest Android Phones and Tabs the next step was to buy Google Chromecast to connect theses devices to TV for media streaming but it required Wifi at home and our Landline phone and MTNL Broadband was in safe custody since 2010 when we went to Jharsuguda. I was not wiling to spend for Landline Phone and we experimented with Mobile Operators taking advantage of Mobile number portability. Finally we sattled for Idea after trying Reliance CDMA and Airtel. For internet Reliance GSM Data was working in the Tab.

For Broadband also I am experimenting with Tikona Brodband which is Wireless till the terrace of our flat where a CPE is installed from where it is wired to the Wifi router installed at suitable location in the home.

The Chromecast is plugged in the HDMI port of the TV and gets power either through USB port of the TV or mains. The Android Phone is used for Setting up the Chromecast to connect to the Wifi Router. After setting up the Cromecast is directly connected to the Wifi Router like other Android Devices and Laptops.

Now suppose you want to watch the Youtube video on your TV you first open the Video on the Phone/Tab or Crome Browser on the Laptop and connect the device to the Chromecast. After connecting the Youtube video directly plays on the TV.

You can also play the local media on your Android devices on the TV. For Laptop you can do it through Chrome Browser and its add-on extensions.

How to make UEFI Bootable Ubuntu 15.04 USB stick on Windows 8.1?

Since many years we download the Ubuntu ISO and use the installed Ubuntu to make a Start up Disk from the ISO to install on the same or other machines. The Start up disk is a UEFI Bootable USB stick.

Today I faced a question on Ubuntuforums about how to make UEFI Bootable Ubuntu 15.04 USB stick on Windows 8.1. I am doing it now on My Lenovo G50-45 Laptop on Windows 8.1. I have the Ubuntu 15.04 ISO on the drive. I have downloaded and installed md5 Calculator Application from Windows Store. I have checked the md5sum of the ISO and it is same as in this file.

I have downloaded 7-Zip 9.38 .msi file from here.
I have a 2 GB USB stick formatted in FAT32 in the USB slot.
I have extracted the ISO on the USB stick using 7-Zip.
I right click on Start Button and select Disk Management and find that the USB drive is Healthy (Active, Primary Partition)
I right click on Start Button, select Power Options/Choose what the power button does and uncheck Fastboot (if exixts)
I reboot holding the shift key.
On reboot I select use a device and EFI USB device and get options on Grub Menu to run Ubuntu without install.

Ubuntu 14.04 on Lenovo Laptop G50-45 with Kernel 3.16.

As written on this post I installed Ubuntu 14.04 LTS in dual boot with Windows 8.1 in December 2014.

The proprietary driver fglrx worked fine till I updated it to newer version on  12th April 2015. After the update I could not login and had to remove fglrx driver and come back to radeon.

Today I installed Kernel 3.16 (original kernel 3.13) through LTS Enablement Stack with following command:

sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic

 The open source driver radeon is working perfectly on Kernel 3.16

This Laptop has Realtek Wireless Network Adapter and its driver rtl8723be was causing disconnections and required reboot to connect again. This is solved by following command:

echo "options rtl8723be fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf

Now Ubuntu 14.04 is working perfectly on this Laptop.

My Android one phone got Android Lollipop 5.1 update.

I bought Karbonn Sparkle Android one installed with Android Kitkat version 4.4.4 recently. Yesterday it got Android version 5.1 update which is called Lollipop.
If you click on Settings/About_phone/Android_version_5.1 number of times it opens Lollipop game (Screenshot below)
