Hello all…
Currently I have nvidia drivers intalled.
What’s the best way to revert back to nouveau drivers, if one was inclined to do such a thing?
Execute the instructions accompanying the original NVidia driver installation script. Failure to do so commonly results in frustration leading to complete OS reinstallation.
Note that nouveau is not the only competent alternative DDX. The upstream default DDX goes by the name modesetting, not to be confused with the kernel’s modesetting process (KMS). With neither xf86-video-nouveau nor a proprietary NVidia driver installed, the modesetting should be used automagically with most NVidia hardware. Both modesetting and nouveau are prevented from use if nomodeset appears on the kernel cmdline, which some versions of proprietary drivers require.
In my experience, after uninstalling Nvidia drivers you might need to reinstall mesa. You can use “unconditional update” in Yast to do that.
