After a badly botched automatic UPGRADE from 20.04 to 22.04.1; a fresh reinstall of 22.04.1 was acomplished in mid September, which installed the nouveau driver and XORG, since my video card is a NVIDIA GeForce GT-710.
After a few screen "suspends" I would lose keyboard and mouse control of the system. The system will track mouse movements, but will not respond to any attempts to select, highlight, or move objects. Keyboard is also unresponsive.
A "power off" reboot is necessary to restart the system. Any files not saved before the reboot are lost, otherwise the system appears to be normal.
The desktop system CPU is AMD FX-8350 (8-core) running at 3.9GHz (max); 8GB ram; two separate 1-TB HDD; 4K SAMSUNG 28" monitor; Logitech K520 and M325 wireless Keyboard & Mouse.
Note: I use the term "suspend", but the system is NOT really suspended, power settings are set to BLACK OUT the screen after 15 minutes of inactivity. The system runs 24x7.
Upon advice from several forum postings, I installed the NVIDIA Driver 470.141.3 SERVER version, still using XORG. This minimized the wakeup problems after "suspend" but did not eliminate them. (The server version was required to be able to use nvidia-settings, and the 470 version is the proper version for a GT-710 video card.)
HOWEVER,
An automatic update (Software manager) that occurred yesterday (17 October) replaced the video drivers and Display manager with "nouveau driver and Wayland"
Now the display will NOT black out totally (it dims to a dull gray), and immediately after I wake it back up, the screen jiggles for about 2-3 seconds and then settles down.
