I performed a clean install of Fedora 12.
I performed fedora forum's NVidia driver "GEForce 4 and below"
install instructions for a PAE kernel.
My card is:
[dabruhn@precision ~]$ lspci | grep nVidia
01:00.0 VGA compatible controller: nVidia Corporation NV25GL [Quadro4 900 XGL] (rev a3)
Upon reboot I get the nvidia splashscreen for 30 seconds than black screen all the while Xorg runs the CPU at 100%.
I've requested help at fedora forums under this post
but no solution was found.
I ran nvidia-bug-report.sh. which is attached. The only error message in the log I could find is:
xset could not connect to an X server
I googled the error message but could not find anything helpful.
I removed the nvidia driver and am currently using the fedora default nouveau driver so the family has a working system again unfortunately without accelerated graphics.
I can reproduce at any time and can provide more information upon request.
Any help is appreciated.
