I'm not quite sure what you mean by that. What I've already tried is using my keyboard shortcuts to adjust the brightness, but without success. I can also outline two scenarios. Scenario 1, only the internal screen connected: - After turning on the laptop, the BIOS logo displays correctly - Then the Ubuntu loading animation appears - Just when I’d expect the login screen to appear, the screen goes black and won’t respond anymore, unless I put the laptop to sleep by closing the lid. -> After waking it up/opening the lid, everything suddenly works correctly.
Scenario 2, a second monitor is connected during startup: - After powering on, the laptop correctly displays the BIOS logo on the laptop screen - Then the Ubuntu boot animation appears (on the laptop screen) - After that, the laptop screen goes black, but I can see on the second monitor that the login screen is actually there. (Second screen turns on, Background color of login screen visible) - I can even drag my mouse to the second screen and see it there - If I now close the laptop screen, Ubuntu correctly switches the display and the external screen is now used as the primary screen; the login field jumps to the external screen. - If I open the laptop screen now, it turns on correctly immediately, and the login screen switches back to the laptop screen. I hope this detailed description has made the problem clearer. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2150832 Title: Wayland black screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2150832/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
