Uninstall a kernel driver?
 

I accidently installed the newest kernel driver and GLX driver 3123, for my Red Hat 7.3 box. How can I remove these and re-install the old drivers. I have to download the newest kernel before the drivers.

Depends on how you installed.

The first thing I'd do is gather up everything needed for going back to the old drivers. Then, kill X.

Ctrl - Alt - F1
#login:root
#password: password

If you run GDM or KDM kill those processes.

#killall gdm
#killall kdm

#fuser -v /dev/tty7

You shouldn't see anything about XFree86 running on that terminal.

#modprobe -r NVdriver

Now feel free to go back to the old driver. After you're finished check to make sure you have the driver build you want.

#cat /proc/driver/nvidia/version

And lsmod to make sure its running.

#lsmod | grep NVdriver

Start X again in the fashion appropriate for your machine.

#gdm
#kdm
