I have just installed the new NVidia driver on my Red Hat 8. But now everything lags. When I move a window over the screen for example, the window lags very much. Everything feels so slow. It did not before!
I run Red Hat with gnome, not kde.
What can be the problem?
Excuse me for my bad english, I from sweden:-)
This has been posted about quite a bit before. nVidia apparently replaced the Render extension with some proprietary thingy that doesn't work with everything. I'm not sure why, since AFAIK Render was working just fine, but hey, whatever, I guess that's why I'm not on the driver team.
One workaround is to use a solid color background if you aren't already. Another is to downgrade to release 3123, since 3123 still used Render.
This may also be cleared up in the next release, but I don't think there's a definite release date.
How du I uninstall the driver I have already installed?
When I try to run: rpm -e <Nvidiafile>, then I got a message that says: "the package is not installed".
Do I have to run the "rpm -e" in some special directory or can I type it in elsewhere?
Or can I jusst install the downgraded file over that one I have already installed (eg. the newer version)?
The RPM database doesn't use the filename as the entry it looks for.
Do an rpm -qa | grep NVIDIA to see what the RPM database thinks you have installed -- probably just NVIDIA_kernel and NVIDIA_GLX, though the version number might possibly be there. It usually isn't, though.
Then rpm -e [whatever that command said goes here] to remove them.
