I have an older NVIDIA card, a GeForce GT 620, which requires the
nvidia-legacy-390xx driver.

I have installed this and all is working well, except I keep seeing an
error:

udevd[]:  Error running install command 'modprobe -i
nvidia-legacy-390xx' for module nvidia:  retcode 1

Of note is that this seems to only happen when I resume from hibernation.

Is this something I need to worry about?  Or how to fix it?

Thanks,

Bob
