[odin beta] Regression: black screen after locking and unlocking multiple monitors #529

Open gvansanden opened 3 years ago

gvansanden commented 3 years ago

What Happened

I installed the beta on my laptop to test if this Elementary 5 bug was resolved. When I lock the screen manually or let it lock by timeout and try to unlock it, it will show a black screen with a pointer, no desktop. If I don't have the external monitor connected, it works fine This seems the same bug I've had since v 5.0

Expected Behavior

The screen should unlock and show the desktop

Steps to Reproduce

  1. install v6 2.connect an external monitor (over hdmi in my case 3.Lock the screen
  2. unlock the screen

Just a small update, I installed tlp and it seems to have helped with this issue.

gvansanden commented 3 years ago

I was wrong, if I wait some time it will just happen even with tlp. As in v5, xscreensaver works correctly

amxmln commented 3 years ago

Could this be related to this? It seems to happen even without an external monitor attached to some people.
