The history, I installed FC5 on a Celeron P4 (2.4) with a mobo with integrated Intel video (i810) and all was sweet. I installed mythtv and got all the modules working and i was almost finished, I just needed to add a PCI Nvidia 5200 to get TVOut functioning and I was done, and thats when the trouble started.

I made a copy of my Xorg config, I plugged in the 5200 and rebooted, I then installed the NVidia driver from the NVidia website rebooted my PC and now it just boots into a FC5 blank blue screen with a mouse pointer. None of the other console screens are available and #1 shows some of the boot history but nothing relevant. BTW this output is on the i810, the Nvidia has no output.

I then rebooted to runlevel 3 and copied back my original xorg config thinking this would resolve my woes but it made no difference, the system still goes through a full boot sequence starting all the services in the GUI boot screen and then when it satys something like 'Starting Avahi.....' it jumps to a blank screen and appears to freeze. I seem to have full network access to the box and am able to SSH to the box no problem.

I am now at a loss as to how I can backout these changes and get back to a working system? How can i remove any installed nvidia drivers? I tried 'yum remove nvidia*' and this seemed to removed some packages but I am not sure they all were removed.

I previously had this Nvidia 5200 card working on this machine under FC4 but then my hard disk upped and died (RIP)

ANy help would be gratefully appreciated.

TIA TomC

Go to the Linux Questions Fedora sub-forum and read the "sticky" note at the top of the page. It explains how installing the nVidia driver from the nVidia site will replace the standard video libraries and break setups with two different video cards installed. It also describes how to avoid the problem by installing a pre-compiled driver (with a separate library) from a repository. (I use livna, but they're others.)
