I do not have windows on my box, but I do have dual boot with ubuntu.

Install grub-pc from sid, and add a file to /etc/grub: cat /etc/grub.d/01_915resolution echo insmod 915resolution echo 915resolution 38 1366 768 8 echo 915resolution 49 1366 768 16 echo 915resolution 58 1366 768 32 Install v86d from the archives, as uvesafb requires it. Then add this to /etc/modules: # framebuffer config and console uvesafb vbemode=0x011b nocrtc mtrr=2 Please check uvesafb docs, as your module options may be different. Then change xorg.conf and place: Driver "fbdev" on your device section. That is. One improvement (that I have not tried) would be to load the uvesafb module in the initrd. For reference, I am running kernel 2.6.30-2 and X 7.4.

Indeed. My glxgears numbers have been greatly reduced when I upgraded to xorg 7.4, although general experience improved. My glxgears give me about 50 FPS, and performance is acceptable for general use. This can see lots of improvement, though. > > - No backlight control.

Backlight control is still missing, and I miss it a lot. Screen blanking is supported with fb, as is RandR.
