Description Simon Steinbeiss editbugs 2018-10-24 22:27:45 CEST
I have two external monitors connected to my laptop through a docking station.

If I disconnect my secondary displays (by undocking my laptop) I notice that the unlock dialog, which is only shown on one of the two external displays, doesn't automatically move to the only remaining - the internal laptop - display.
Instead, my session is revealed. I cannot interact with it, because there seems to be a transparent toplevel window or in any case my keyboard and mouse are grabbed. However, I have no way of unlocking my session.
When reconnecting my previous external setup, the unlock dialog shows up as before on one of the external displays and I can unlock normally.

It looks like we should be able to plug into the GdkScreen "monitors-changed" signal to detect connects/disconnects and redraw everything. I'll look into this sometime this week.
