Comment 7 for bug 1894454

Thank you for your suggestion. I was using driver version 440 when desktop freezing first started. I disabled all power savings, adjusted the nvidia gpu performance to maximum and upgraded the driver to latest stable version based on user experiences and recommendations in various forums.

I didn't paid attention to exactly after which action this problem started, it was a mistake of mine. I'm constantly updating my system. i suspect it started after a new kernel update.

I've downgraded the driver upon your suggestion. I still have all power savings disabled and gpu performance adjusted to maximum. I'll observe and update this issue in case desktop freezing continues.

Meanwhile I attached a video showing the freezing instant. Desktop freezes like this, keyboard and mouse become unresponsive, sound of playing media file continues to be heard for a while.
