Please open the 'Additional Drivers' app and try installing a graphics
driver from Nvidia instead.
** Summary changed:
- System unresponsive to keyboard and mouse clicks when changing screen
background
+ [nouveau] System unresponsive to keyboard and mouse clicks when changing
screen background
Thanks. It looks most likely the freeze is a kernel bug in the 'nouveau'
driver:
Jun 30 09:41:31 My-System kernel: [TTM] Buffer eviction failed
Jun 30 09:44:35 My-System kernel: [ cut here ]
Jun 30 09:44:35 My-System kernel: Trying to vfree() bad address

Additional info...
Upon invoking the freeze, Ctl-Alt-F3 sometimes brings up a terminal session on
tty3.
If it does, Ctl-Alt-F2 will switch back to GNOME which will remain frozen for a
while, but will allow switching back and forth with the Ctl-Alt-F# keys.
Running "top" on tty3 shows no process
Here is the journalctl report.
Line 3144 is immediately prior to hanging GNOME.

If the mouse cursor still moves then that means Xorg is still running
and it was gnome-shell frozen. But we need to find out if it was just
frozen or the result of a crash. Please use this command:
pidof gnome-shell
to check the process ID before and after the freeze and tell us if it
changes.

2. Open a Terminal window and run 'top'. Now reproduce the problem
again. While the problem is happening does 'top' report any process
using very high CPU?
