Public bug reported:
First thing I notice is that the mouse cursor freezes as I'm using it,
then I hit the CAPS LOCK key and the LED indicator doesn't respond. Then
I try the "REISUB" command, but it doesn't do anything either. Only a
hard reset works, pressing down the power button for a few seconds.
How to reproduce?
I couldn't figure out a consistent method. It is still random to me, although
it seems to happen more often when I'm running Xfce (Xubuntu) on a recent
kernel (4.17+). Xfce's default image viewer seems to be connected to it, as
well. Most of the time I was having multiple instances of it when everything
froze.
Version: Ubuntu 4.18.0-10.11-generic 4.18.12
System information attached.
Also happens under Arch Linux and Fedora.
