Comment 12 for bug 451518

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).
