I had pretty good experience with nv in the past in terms of stability. There really should be something in one of the Xorg.*.log files that looks bad. Maybe try entering runlevel 3 telinit 3 which is text mode, and after logging in as root, type startx then try to provoke the crash, see what is left by the "dying breath" on the text console after the crash and once again look in /var/log/Xorg.0.log at the end. You can go back to normal runlevel 5 afterwards with telinit 5 > Sheesh, my Linux skills are rusty.

Ooooh yes, I had to get freedos working on a CD to update a BIOS the other day, almost all my DOS-fu, dating back to 8086 times, has made way for Linux knowledge I am happy to say. Another thing to try to see if you can tie the problem down to the X driver is to set the driver to "vesa". This is ultra-stable and boring. If firefox can start with that then it strongly suggests nv is needed to make the problem. -Andy
