Thanks. The best guess I can make is a problem in upower or the Nvidia
driver (comment #15). Those are definitely performance problems (100%
CPU for no obvious reason) and could well explain why the keyboard stops
responding.
Maybe next we need to look at the system log in detail... If you can
recover from the problem without rebooting then please run:
journalctl -b0 > curlog.txt
If you have to reboot to recover from the problem then please run this
after rebooting:
journalctl -b-1 > prevlog.txt
and send us the resulting log file.
