Xubuntu/Ubuntu 12.04 on Samsung NP530U3B (NP530U4B)

1. I installed xubuntu on the 10gb partition of ssd (expresscache). I use windows as well, mostly because of the lack of three finger support and suspend, as of now. I haven’t felt any performance decrease (windows) by the absence of expresscache.

I also use windows bootloader with a bit of help from http://www.linuxbsdos.com/2012/05/17…and-windows-7/ because of the grub issue.
I keep home and var on a hdd partition and tmp on ram. See: http://forum.xda-developers.com/show….php?t=1627197

2. The overheating and battery issue exists originally because of bad default kernel options.
Heating can be fixed by enabling active state power management and battery issue can be solved by the specific i915 options from http://www.phoronix.com/scan.php?pag…15_power&num=1

In short, what @sacapeao did –
GRUB_CMDLINE_LINUX_DEFAULT=”pcie_aspm=force i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1″
in /etc/default/grub.

Also installing jupiter helped. http://www.webupd8.org/2012/03/jupit…itches-to.html

3. The suspend doesn’t work by default. It works perfectly fine by following the step 2 of http://thecodecentral.com/2011/01/18…ot-working-bug

4. The touchpad doesn’t have three finger option. touchegg doesn’t work (segfault). It seems to be a known bug and I hope it gets rectified soon.

5. While partitioning, I had to shift my recovery partition and in the process I have lost the use of my F4 recovery key. I intend to reclaim it and am in the process of finding a solution.

Any help with the touchpad or recovery is welcome!

New Music Players: Minitunes and Guayadeque

Two awesome (yes, much more awesome than gmusicbrowser) players/managers are in development. Well, Guayadeque is pretty much developed and is extremely usable, but a bit ugly. The ubuntu repo version did not work for me, hence I picked it up from the site – http://nchc.dl.sourceforge.net/project/guayadeque/guayadeque/0.3.1/guayadeque_0.3.1-natty-2_amd64.deb

Minitunes, otoh, is extremely pretty, but under extensive development. Fingers crossed. It is available in ubuntu repos.

Both are extremely fast:
gmusicbrowser – 80mb
guayadeque – 55 mb
minitunes –  60 mb

The best one as of now is Guayadeque. Go for it.

Remedying the glib go error in ubuntu

If you encounter the glib gio error while firing an app from the commandline/shell, such as this one:

GLib-GIO:ERROR:/build/buildd/glib2.0-2.28.6/./gio/gdbusconnection.c:2279:initable_init: assertion failed: (connection->initialization_error == NULL)


use the following script. It exports the dbus session and then runs the apps. Simply use: ed.sh <command> or if you have already used a long command and failed: use the trick “ed.sh !!” (!! replicates the last command).

Download the script from: https://gist.github.com/a664a61a49296da16e47

Google Chrome: Sharing Profiles with a Linux OS

Some of you might be wondering how to share a google chrome profile between a windows and a linux operating system. Copying or creating a symbolic link doesn’t seem to work as the extensions go haywire. The reason is the use of “\\” in the profiles created in windows. Use the following command to change the path names in the Preferences file to use a ‘/’ instead of ‘\\’.

sed -i ‘s/\\\\/\//g’ ~/.config/google-chrome/Default/Preferencesas

Happy chroming! Its still the fastest starting browser.


Tata Photon – How to obtain Usage details

There are many ways. But my favorite is to use a bookmark for the official usage site: 
https://www.tatatele.in/prepaidPhoton/postUsage.do?mdn=<your photon phone number>&SOURCE=postpaidMCCI&d-4030679-p=1

This is for postpaid connections, for prepaid, I do not have any clue. If your accounts page shows the usage stats, you can open the frame in a new tab and get that link.

The only drawback is that its not real time. The delay is generally of 3hrs, but sometimes it may go upto 12 hrs, depending on the server updates. For real tme updates, I use:
Windows: Networx.
Linux: vnstat with its php frontend. http://humdi.net/vnstat/ & http://www.sqweek.com/sqweek/index.php?p=1
