Daemon needs to be restarted after logging in when autosetting xrandr props

[Vandino86]

UPDATE: The keyboard shortcuts error I originally mentioned here is titled "lxqt-panel" and says "Volume Control: The following shortcuts can not be registered: 'XF86AudioRaiseVolume'". I also get these for other shortcuts. I'm not 100% sure if this is an lxqt-panel error instead, however.

I'm using a 2560x1440 monitor that has an xrandr property called scaling mode that is set to None by default. However, I want it permanently set to Full aspect, so I tried putting the command xrandr --output DP-1 --set "scaling mode" "Full aspect" in the file /etc/X11/Xsession.d/45custom_xrandr-settings. While this successfully set scaling mode to Full aspect after rebooting and logging back in, I noticed that when logging back in, an error regarding keyboard shortcuts would appear in my notifications (bottom right of the screen) and my keyboard shortcuts (volume up + down, Alt+F1 to open/close main menu, etc.) wouldn't work. Sometimes, the panel will be frozen for 20 seconds after logging in and only afterwards will I get the shortcuts error. Going to Session Settings > Basic Settings and stopping and then restarting Global Keyboard Shortcuts in the LXQt Modules section makes the shortcuts work again. I've also tried using using an autostart entry with "Start only in X11" enabled to set scaling mode instead, but I get the exact same results, even with "Wait for system tray" enabled.

Is this an issue on LXQt's end, or am I not persistently setting xrandr props the right way?

I can't imagine a connection between the shortcuts and xrandr settings.
I tested on my laptop the autostart method with xrandr --output eDP1 --set "scaling mode" "Full aspect" and couldn't reproduce any issue.

Which display manager are you using? I forgot to mention this when I originally posted my issue, but I'm using SDDM 0.21.0.

UPDATE: I managed to get it working consistently by adding a 5 second delay before xrandr following these instructions. My autostart entry file (~/.config/autostart/Set scaling mode to 'Full aspect'.desktop) looks like this now:

[Desktop Entry]
Exec=bash -c \"sleep 5 && xrandr --output DP-1 --set \'scaling mode\' \'Full aspect\'\"
Name=Set scaling mode to "Full aspect"
Type=Application
Version=1.0

I usually use greetd, but in this case I used startx from tty to test. And I can't also imagine that this could influence here, maybe the window manager, which one are you using? Window manager register shortcuts too.

But good that you found a workaround.
