I was really excited when i installed Jaunty two months back! It was really happening destro with soo many updates. I installed it and started playing around with it and suddenly to my surprise system just hung. The cursor moves but the nothing responds, only way to get around the problem was hard reboot. Even ctrl+alt+F2 didn’t work. It never happened with me before on ubuntu. I thought this should be some minor issue but it kept happening within some intervals. 😦
So got irritated i started searching and then i came to know that it was a big bug in jaunty with intel drivers. You can read about the issue here and bug filed here They blacklisted the intel driver so that visual effects couldn’t be turned on, since it causes freezing issues. However I had found a hack to remove the intel driver from blacklist and turn on the visual effects. This was causing the freezing problem. The only option was to turn off the visual effects which i can’t do since i use the AWN and it doesn’t run unless visual effects are turned on.
There was no solution, no one knew properly what was the problem. As the time went by, i upgraded to Karmic Koala. The freezing problem suddenly stopped but since it was alpha release it was very unstable, so i had to revert back to Jaunty. Then to my relief there came an update in bug page that fix for Xorg-intel drivers has been released. I installed it even it didn’t seem to solve the problem but for most it worked out. No idea why, it didnt work out for me 😦 Then i saw a post about reverting to previous intel driver on ubuntu help. I tried it and now no freezing problems.
The solution : Reverting the Jaunty Xorg intel driver to 2.4
Installing the package
Add the following lines to your /etc/apt/sources.list:
deb http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main deb-src http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main
Import the appropriate GPG key:
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xce90d8983e731f79
Install the driver:
$ sudo apt-get update $ sudo apt-get install xserver-xorg-video-intel-2.4
According to the dev at ubuntu this problem should not be there in Karmic Koala
