I am trying to determine who is responsible for the frequent screen freezes that I am having after the screen has been "blanked" by the 15-min power timeout.

When the screen freezes, the mouse can be moved around, but cannot select anything.

The keyword is "dead" except for "alt-F2". (TAB and windows keys do not function. Ctl-ALT-T will sometimes respond with a terminal window.)

If, however, I press alt-F2 and enter "restart" in the window, the system will sometimes recover. If it does not. then I have to resort to a power-off reboot to recover the system.

So, my quesion is: "Who is responding to the "restart" command?" and "What is it really doing?"

    That is gnome-shell … responding and restarting … restart is an internal gnome-shell command that reloads your gnome session. – Raffa Dec 08 '22 at 08:08
  • @raffa Interesting, so Gnome is running "okay". Does that imply that my hang is X11, or maybe the screen driver or one of the many "routines" between them? – wb4alm Dec 08 '22 at 09:18

  • @Raffa thank you for the assistance, but due to the fact that grqphic problems have reoccured everytime UBUNTU 22.04.1 does a software update, I have decided to abandon UBUNTU after 16 years of use. This is even after multiple times (4+) of doing a fresh install of UBUNTU 22.04.1. Surprisingly enough, Mint 21 runs on the exact same hardware with no dificulties or faults. – wb4alm Dec 09 '22 at 18:49
