Screen Preferences testing

[trunkmaster]

Test display management on real hardware (relayout, enable/disable, open/close laptop lid).

Hi, I've been testing this since I got it running properly.

Multi-monitor support doesn't work, only my laptop screen lights up while the external monitor stays black but the mouse still shows up on its edge.

When closing the laptop lid it or removing the cable to the external monitor the other display is then set as the main one properly.

Closing the lid sometimes works but most of the time just causes the screen to go black and crashes.

Hi, that's good but I need more information.

When? On Login start, after log in or while changing Screen preferences? xrandr command output may help to understand exact settings on Xorg side.

Closing the lid sometimes works but most of the time just causes the screen to go black and crashes.

Most of the cases may be related to Linux itself. Please check video driver installed, power settings, exact conditions on crashes. For example, closing the lid may lead to suspend and after open Xorg may crash.

Multi-monitor isn't working in any condition. Here's xrandr output, eDPI-1 is my laptop screen:

Will test it more to see what exactly causes it to display a black screen or crash.

I suppose it's a closed lid with connected external monitor to HDMI port. sudo journalctl /usr/NextSpace/Apps/Login.app/Login may provide additional information from login window point of view. At start Login.app prints "Screen size" and "Display frame" information.
