16. Using onboard video card with acceleration on Optiplex 990 on Debian

NOTE: another issue debian users should be aware of is the failure to reboot on sudo shutdown -r now. The fix is easy though: change GRUB_CMDLINE_LINUX in /etc/default/grub to read GRUB_CMDLINE_LINUX="reboot=pci"

--Start Here ---
The videocard (nvidia quadro something or other) my work Optiplex 990 came with only has a 'displayport', and the supplied adapter for it only has DVI-D (no analogue signal, so a VGA converter won't work). Since my 24" monitor doesn't have DVI, and I hate HDMI, and at the same time appreciate graphics acceleration (can't live without my wobbly windows in compiz), I had to generate an /etc/X11/xorg.conf which would allow me to use the motherboard graphics capabilities. Here's that xorg.conf (ripped out the video card, used smxi to generate an xorg-driver dependent xorg.conf):
