Bug Description
I have a Dell XPS 13 9343 with external display link monitor which I use in non-mirrored mode as two different screens. If the screen locks and suspends (simply locking is not enough) if I tap a key/move the mouse/etc the laptop screen comes up and the external monitor flashes on, but then the external monitor goes blank (but I can see its backlight is on). If I login, the desktop seems to think it is off and all of open windows are rearranged (it even puts some on different workspaces). The only thing resembling a workaround is if I tap a key, watch when the external monitor is blank, then turn off the external monitor, then turn it on, then unlock the screen. This isn't great though-- some windows are invisible and rearranged and I have to cycle through the different workspaces to find them and put them back.
