Ubuntu suddenly freezes
- by tapan
I've a strange problem with my ubuntu 10.04 installation. Whenever i boot into ubuntu the entire system freezes / hangs soon after (~ 2 mins in). This problem exists on my windows 7 installation too. However if i start World of Warcraft or Warcraft on windows it doesnt hang for the duration i'm playing the game. After i stop playing and exit the game my laptop hangs inside 2 mins. Here is when it gets weirder. If i disconnect the charger, the laptop doesn't hang.
However when I start it in ubuntu recovery mode and drop to root shell and use the 'startx' command everything works perfectly. I cannot figure out what the problem is.
i have an intel core2duo 2.2ghz processor, intel mobile 965 graphics, 2 GB RAM

Also the kern.log doesn't show any errors. What I want to know is what might be the problem, how i could test for it and if there are any solutions I could try. Thanks :).
