Linux on Dell: X and nVidia

xorgcfg

I had pretty good experiences using xorgcfg creating the initial xorg.conf. I had some disturbing events where X made the kernel reboot. I have seen some references indicating that this might be due to APCI, so a good advice is to remove apci from the kernel and use apm instead.
