[Bug 451518] Re: [i945G] karmic: INFO: task i915/* blocked for more than 120 seconds.

I have switch to vesa driver instead of intel driver and this is enough
for me. The intel graphics card on Dell GX260 in not very good at 3D
acceleration anyway. I have noticed that lsipci shows that my graphics
card has 128 MB of RAM which is not true - It has only 8 MB RAM (Region
0).

I have changed the option Driver in Section Device from intel to vesa,
added VideoRam 7680 and disabled all the modules in Section Module . The
formula for determing VideoRam is (Video Memory)*1024 - (Region 1 size
from lspci).

My xorg.conf  looks like this :
