Description Edward 2022-08-11 00:49:43 CEST

Description of problem:

Display resolution is set to 1680x1050. If there is no activity for ~10 minutes, xscreensaver starts up. When logging back into the desktop through xscreensaver, the display resolution automatically switches to 1920x1080 each time, using the Xfce desktop. On-board video is connected to the monitor via a DVI-to-HDMI cable (DVI output from video, HDMI input on monitor).

Version-Release number of selected component (if applicable):

5.45.1

Many search results show up that this is a common Xfce problem, that the resolution wont stick until you properly set up your xrandr (arandr is a GUI for it).

- properly setup your monitor via built in tools: https://docs.xfce.org/xfce/xfce4-settings/display

- properly setup xrandr/xorg

I originally set the monitor resolution using the Xfce GUI at first, which is the same as on the Xfce link you provided.

I just installed arandr, it was already set to 1680x1050, saved it anyway, but it made no difference. The resolution flipped back to 1920x1080 when I logged back in through xscreensaver.

The only other option I can think of, is to add an xrandr command to autostart, but there's no guarantee that will stick once/if xscreensaver is launched/exited.

As /etc/X11/xorg.conf is autogenerated by XFdrake, I do not want to manually touch that.

Comment 3 Edward 2022-08-11 12:56:32 CEST

I just ran arandr as root, changed the resolution back to 1680x1050 and applied it. Will check to see if that sticks. If not, then I'll have to try xrandr in autostart.

One suggestion upstream was to edit xorg.conf. MCC was able to do this, now with the desired display resolution holding, but Xfce itself is now displaying a Display settings window when the system comes out of suspend/sleep/black screen. Xscreensaver had since been turned off, now displaying a blank screen in its place. Desktop reappears once the mouse is moved.

Another suggestion upstream to delete the Keyboard Applications Shortcut referring to "Display", did not work (screenshot attached).

Comment 6 Edward 2022-08-14 01:41:15 CEST

Additional steps were taken, in addition to the modification of xorg.conf (what was required), which resolved this issue. One of the forum admins said there have been some changes made to the display restoration/recognition functions in xfce4-settings, so I believe a new version would eventually be forthcoming.

Status: NEW => RESOLVED
Resolution: (none) => FIXED

As we have done nothing on Mageia side, changing status to WORKSFORME (it is a matter of proper settings).

Resolution: FIXED => WORKSFORME
