Description Ralph Birt 2018-01-30 05:47:36 UTC

Twice in the last two days the system has completely frozen while I was resizing a window.  The first time I was resizing a Konsole window.  The second time I was resizing a Firefox window.

Both times the system was completely frozen and to recover I had to reset by holding the power button for 5 seconds.

This is on X11 or Wayland?

Comment 2 Ralph Birt 2018-01-31 05:08:10 UTC

This is on X11.

Is the mouse cursor still moving when the system is frozen.

Comment 4 Ralph Birt 2018-01-31 05:48:43 UTC

No, the mouse cursor is frozen too.

Comment 5 Martin Flöser 2018-01-31 17:20:36 UTC

In that case: it's not KWin. The mouse cursor is provided by X and this means that X is frozen. You need to report to X developers.

Btw. it's quite likely that X is also a victim. As you mention Konsole it is possible that this is a graphics driver issue.

Okay, thanks Martin.
