lubuntu mantic live - on enabling monitors crash

[Chris Guiver]

Lubuntu mantic live test on
- dell [optiplex] 7050 (i5-6500, 16gb, intel hd530/i915, radeon cedar)

The system boots using only the (3) i915 connected displays; but I also have a radeon card with (2) more displays.

I opened Monitor.Settings & clicked 'enable' on the two 'disabled' displays, I may have also moved screens around too, but on clicking APPLY the session ended (and after a delay I was back at greeter).

Crash files exist in /var/crash for Xorg, libexec_kf5_kscreen_backend & lxqt-globalkeysd (all with some date/time)

I suspect lxqt-globalkeys crash is just consequence of Xorg going down; but crash file existed...

** expected outcome

On alteration in Monitor.Settings of config, clicking apply will action change

** actual outcome

Change made in Monitor.Settings (2 disabled screens enabled) & on clicking APPLY session ended
