Fixing Windows / Screen Tearing on Intel Graphic Card – Linux

I had some mild / serious screen and window tearing problems when moving windows, scrolling through the browser and the general KDE Plasma UI could be a bit laggy. The problem was reduced if I switched my rendering backend from OpenGL 2.0((Hardware rendering  – the default) to Xrender (Software rendering).

The system is a work laptop – a Thinkpad E550-. It comes with an Intel Broadwell Chip. Running lspci -c video spit out this following: Read more

Get Thunderbird to minimizing to tray instead of closing

One of the first set of things i do when i install a fresh (k)ubuntu is change the default email client. Both evolution (ubuntu) and kmail (kubuntu) don’t just cut it for me, they always seem bloated and buggy. I am a KISS guy -not that kiss (fine am that kiss too but the kiss i refer here is the Keep It Simple Stupid kind of kiss 😀 ) hence i find thunderbird to be the email client that just suits my needs. It doesn’t try to take over the world or make dinner for me. Its first and foremost an email client and its keeps with the Unix philosophy of do one thing and do it well.

However one thing i have always wish it had was the ability to run in the background so that if i close thunderbird i want it to minimize to the system-tray/notification area and inform me real time when i have a new mail. Read more

Ubuntu Jaunty Jackalope on Dell XPS M1330

So Ubuntu Intrepid Ibex turned out to be a bad experience on my dell m1330. Many things that worked out of the box with Hardy heron got broken on Ibex. Things like Finger print reader, bluetooth, Graphic Display, Audio, all had one problem or the other. I was able to walk around most of the issues, although some were just unfix-able (like the screen corruption that i get when i enable compositing metacity or compiz) could not be fixed.

When Jaunty alpha6 was announced with many folks on identica claiming it to be very stable i decided to make the switch. I have since been running Ubuntu jaunty jackalope on my laptop. People say that the grass on the other side is always greener,well that was how running jaunty on my dell m1330 turned out. It wasn’t perfect and although i noticed many improvements from intrepid ibex like faster boot, better notification system, better support for suspense and hibernation, they were also some huge show spoiler like the Intel graphic regression which seem to affect the Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) graphic chipset the most, causing the system to hard freeze requiring me to have to manually power down the machine. This issue got really bad that i had to downgrade to ubuntu hardy heron (which ran perfectly on my system) while i waited for walk rounds to the problem.

Login Graphically to A Computer in a Remote Location

The ability to login graphically into any computer from a remote location has a number of uses. In my case it allows me to create a setup where students in my school can easily login graphically into the universities computer lab and use many of the applications which are installed there (like Matlab which is only licensed to run on our lab computers) It also allows me to log into my work computer from home. To create this setup we would need a tool called Freenx.

Blueman – An Awesome Bluetooth manager for Ubuntu

Bluetooth support has always been shaky in gnome. The default bluetooth manager is often very basic and unintuitive. Things like connecting to an audio or input device and Connecting to 3G/EDGE/GPRS via dial-up were either impossible or  not easy and straight forward to set-up. Bluetooth support took a nose dive in Intrepid Ibex when even the basic bluetooth support  got broken, when i updated to Ubuntu 8.10. sending files from my laptop to my Nokia Internet Tablet become chore.  sometimes it worked, most times it doesn’t. “well shit happens you cant always have it all” that was my attitude to the whole bluetooth problem till i found out about Blueman.

Elisa : A Nice Media Center for Ubuntu

When i started using Linux some 2 years ago, one application i really wanted to have was a media center. I liked having all my multimedia controlled by one software, like a one stop media shop (more or less)

On windows i used the windows media center which is a very cool tool for my needs. Unfortuntely when i migrated to Linux i was unable to find a program that does what i wanted. i tried MyTV but it was too TV centric i don’t have a TV Card- beside was a witch to configure. I just wanted something that was easy to install, easy to use, and just works.

How to install SageMaths on ubuntu

how i got to install sage on ubuntu..

Sage is a free open-source mathematics software system licensed under the GPL. It combines the power of many existing open-source packages into a common Python-based interface.
you can read more about sage here http://www.sagemath.org/tour.html
unfortunately sage is not available in the Ubuntu repositories and in-fact any repositories as a .deb package. ( at the time of writing this). did you say compiling? dont even go there i tried building it. and failed woefully. fortunately i found a nice and easy to install it on Ubuntu. there is a binary package already compiled for Ubuntu. which makes installation on Ubuntu quite easy and straight forward.

Ubuntu Intrepid Ibex On Dell xps m1330

Installing Hardy heron on my laptop was quite a breeze. the only thing i had to configure was the finger print reader. but even that went quite well after following an easy guide.
However Ibex was not that easy. Ibex was released some 6 days after i got my dell so it was good timing. but my first experience was very unpleasant. and things that just use to work on hardy without an extra config didn’t work on Ibex.Things like my Finger print reader stopped working even after i followed the guide that worked so well on hardy. Webcam too stopped working. that worked on hardy without me lifting a finger. my inbuilt mic too was affected. in the end i had to downgrade back to hardy and waited for the dust to settle and for the real geeks to figure out all the issues :). well the good news is that they have. am back to Ibex and must of the issues have been resolved. well not yet out of the box though but here are what i did to fix the issues.

Ubuntu Hardy heron On Dell xps m1330

Ubuntu and Dell XPS M1330

Recently decided to vote with my pocket and stop paying the MS tax. Hence i ordered a laptop that came pre-installed with Linux. i wanted some sleek,powerful and just works with Linux. and the Dell xps m1330 was just want fitted my need. out of the box it just works mp3 and all. it also comes with a reinstall partition which is meant to reinstall the system to it factory state in case you break your computer. what really impressed me the most was the finger print reader which (through thinkfinger) would allow you to use your finger print for  GDM session login, Screensaver unlock, Sudo and gksudo prompts, PolicyKit authorization. now tell me that is not cool.
