Re: [Solved] Random Freezes and Compositor Crashing with nvidia 450.57

(sorry mods, i "reported" the thread instead of replying)

I may be wrong, but that message from kwin may be related to a deficiency of the nvidia driver in saving and restoring the video memory when resume from hibernation/suspension.
In the past the situation was worse and you just get a garbled desktop on resume.
Kde devs worked around that.


Help me to improve ssh-rdp !

Re: [Solved] Random Freezes and Compositor Crashing with nvidia 450.57

The KDE devs recognized that it was a driver regression from nvidia and provided the current fix. It does prevent kwin crashing on resume but I guess it this is the fix for now until nvidia comes back with it's own solution.

EDIT: I will close this thread now. The latest driver update has fixed the  resume from suspend and the artifacts problems on resume. I gathered restarting desktop effects on resume is to be expected.
