GNOME Bugzilla – Bug 790687
Screen Settings lost after logging in from lock screen
Last modified: 2021-07-05 13:43:38 UTC
My screen settings were: * External Screen ON * Internal Screen Off After locking my screen and then logging back in, these settings are lost. Both screens are ON, which is my main issue. Before a recent minor upgrade somehow the internal screen would be on, but not display anything. It's backlight would be on and I'd have the glitches that you see when using a high resolution screen on a two weak graphics card in Wayland. The main issue occurred only after upgrading to Gnome 3.26 along with F27.
X or wayland session?
thanks for looking into it. I'm running wayland
Please attach a file with the output of the command "sudo modetest" And also, please attach the output of the following two commands: gdbus call -e -d org.gnome.Mutter.DisplayConfig -o /org/gnome/Mutter/DisplayConfig -m org.gnome.Mutter.DisplayConfig.GetResources and gdbus call -e -d org.gnome.Mutter.DisplayConfig -o /org/gnome/Mutter/DisplayConfig -m org.gnome.Mutter.DisplayConfig.GetCurrentState

Hm I tried quickly reproducing the problem for these commands, but I couldn't. Maybe the problem is when the screen goes to standby after some minutes. I'm also seeing the problem that the external screen is suddenly configured for a really low resolution, I think 1024. I need to re-plug it to be recognized with the right settings.
Actually the too low resolution is 1600, and I'm still seeing the issue. Recently I noticed that I've been running X instead of Wayland for a while, and I think the issue occurred even there. Could you make sense of the logs? Thanks
I just could reproduce the issue, I'll attach again the output of the files while my external screen shows 1600 only.

GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org. As part of that, we are mass-closing older open tickets in bugzilla.gnome.org which have not seen updates for a longer time (resources are unfortunately quite limited so not every ticket can get handled). If you can still reproduce the situation described in this ticket in a recent and supported software version, then please follow https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines and create a new ticket at https://gitlab.gnome.org/GNOME/mutter/-/issues/ Thank you for your understanding and your help.
