previously, i was working on ubuntu 10.04 without this problem
NOW, i have installed ubuntu 12.04 and it's so beautiful,, it's completely with my hardware (touchpad, ati card ..... etc)
i have installed some applications i need, like netbeans, vlc, google chrome, gimp, pidgin.... and other apps.
but sometimes my laptop fully freezes ,, i cant move mouse and keyboard not responded.... i cant do anything except for press power button on my laptop for 7 seconds to shutdown
often, i get this problem after few seconds of the laptop return from suspend..
i have this laptop:
dell inspiron n4030
Intel® Core™ i3 CPU M 370 @ 2.40GHz × 4 ,,,
4 GB of ram
512 MB ATI Card -- Mobility Radeon HD 5430 Series
ubuntu 12.04 64-bit
I have the same problem... Are you using the fglrx driver? because, at least with me, when i use the open source driver, my computer freezes, but just for some seconds, then compiz restarts... I'm using Unity 2D now, and it never happened again... I believe that this is a compiz bug.
About a week ago I've seen that a patch, that i've got via software updates, fixes the GPU hang, it wasn't related to the FGLRX driver i guess, because i didn't turned off my computer for a week, just suspending it, and it usually happened every day. Now i'm happy =)
