Hello Elizabeth,

Thanks for the update.

In my case it seems that the hangs never happen immediately after booting.
Instead, most of them happen few hours after. That suggests to me that the
problem might somehow be related to memory usage (acessing invalid buffers? not
enough memory to continue?). In two of the four documented cases (so far), the
hang occurred as excessive amount of output characters was printed into xterm
(infinite loops, faulty scripts). That could either be linked to the memory
problem or to another similar root cause.

Also, please note that I use i3 WM instead of KDE in my setup. Sometimes I use
two displays (via HDMI) in extended mode (not mirror) However, in all instances
so far, the hang occurred in a single display mode.

Best,
Petr
