I remember getting this once I was tweaking some xorg.conf options
to improve performace. Sometimes it is quite anoying since the fonts
get totally unreadable. I checked xorg.conf but that configuration
file is not used anymore... Watching videos in youtube is funny as
well, i get to see the video but the video refresh is very slow like
if there was no DRI however this is on if i do glxinfo. The graphics
card is a ATI Technologies Inc Radeon Mobility M6 LY
Yeah there is something weird going on with this one:

A good thing to do would be to check in launchpad and other bug trackers
if there are some issues with the current xorg driver for this card.
The problem is related to KMS (kernel modesetting) which is a new
thing getting enabled in recent kernels. The radeon drivers for those
cards dont support it well. Passing radeon.modeset=0 on boot fixed my
weird graphics curruption. It doesnt seem to happen with the -generic
kernel though.
thanks antonios, where should i add that? i see that this should go in
the kernel options at menu.lst but i am using GRUB2 and there is no such
file anymore.
