Intermittent lock screen failure (grey screen) #17

Open jacobgkau opened 7 months ago

jacobgkau commented 7 months ago

On serw13, I sometimes see a grey screen with no dialog when I try to lock the screen. This seemed to happen less with cosmic-greeter as my DM than before when I was using GDM, but I just had it happen again.

These seem to be the relevant logs (before this was me moving panel applets around, and after it was me running commands in the TTY):

Here's the whole journalctl file in case I missed something (note that I had to restart COSMIC Greeter earlier in the boot to get the login screen working in the first place): cosmic-greeter-lock-screen-failure.txt

This can be successfully worked around without losing the session using the following commands @jackpot51 gave me:

killall cosmic-greeter
WAYLAND_DISPLAY=wayland-1 cosmic-greeter

I think this might be the same as https://github.com/pop-os/cosmic-comp/issues/288

I put it in cosmic-comp because killing cosmic-comp from TTY gets me out of it, whereas killing cosmic-greeter seems to have no effect. It could still be the greeter, though.

jacobgkau commented 7 months ago

You mentioned in that issue that killing cosmic-comp kills your session. Killing cosmic-greeter and restarting it doesn't kill the session. With that in mind, it seems like cosmic-greeter is running on top of cosmic-comp, the issue is in the greeter, and killing cosmic-comp just kills the greeter since it kills everything. (Just a theory.)

Edit: The key with killing cosmic-greeter is that you have to also start it again afterwards, so that could be why you thought it didn't do anything before.

Ah, that makes sense. I'll close https://github.com/pop-os/cosmic-comp/issues/288 in favor of this one then

WatchMkr commented 4 months ago

This issue seems resolved. Please confirm.

I have not seen this happen for at least a few weeks, and have eased back into using the lock screen more regularly. I'm thinking it's probably fixed, but I'll wait for Jacob's feedback as well before closing.

this issue is pretty severe for me, i've tried both greeter and gdm and it goes to greyscreen 100% of the time when I lockscreen

i'm running the latest build from here https://copr.fedorainfracloud.org/coprs/ryanabx/cosmic-epoch/
