after install, invoking nvidia-settings shows no driver

[rob grune]

Using MUON, installed the nvidia driver metapackage for 450.
[note; this bug applies to all packages, 390, 330, etc].

Using terminal, when invoking nvidia-settings, the nvidia window is completely blank and the following errors are reported...

(process:18974): Gtk-WARNING **: 08:23:46.948: Locale not supported by C library.
        Using the fallback 'C' locale.

Daniel:

Thanks for your email.  Hours after I posted the bug message, my
computer would not boot to the Kubuntu 20.04 o/s.  I determined the
culprit was the Nvidia software.  I attempted to purge the Nvidia
drivers via the terminal, but no success. I was then forced to perform a
fresh install of Kubuntu. The fresh install succeeded, with the Nouveau
driver. I then installed the Nvidia 390 driver package, via the muon
package manager.  This succeeded, and I am happy to report the Nvidia
390 driver is properly installed and the nvidia-settings app runs properly.

I am very reluctant to again attempt the install of the 450 driver
package. The days for downtime and frustration to re-install are simply
too great.  Thanks for your attention and understanding.

regards,
RG.

I'm going to go ahead and close this given we are missing some information and I've reported a similar bug (1988209) already.
