[WARN] getMonitorFromVector called with empty monitor list
If I launch Hyprland in systemd using uwsm while there is no physical monitor attached, it immediately crashes. If I launch it directly with an equivalent config, it sits happily without a monitor until I run hyprctl -i 0 output create headless [name]. The only remarkable difference between the logs is that the log for the crashing instance contains as the final line [WARN] getMonitorFromVector called with empty monitor list.
Until just now, I was clueless as to why the systemd version had a problem with being launched without a monitor while the non-systemd version was just fine, but now I am taking this educated guess:
In the non-systemd version, the only autostarted programs are launched with exec-once in the hyprland config, which does not run until there actually is a monitor to display the content on (which I know to be true because of exec-once=hyprctl output create headless virt-1 not working to initialize a headless setup with output).
With systemd however, graphical systemd-services, including those defined by .desktop files in autostart directories (like, say, KeepassXC) are also executed, and they don’t care about no monitor being attached. Hyprland does care however, once it tries to assign the new window to a monitor. And it crashes.
Assuming my guess is correct, my question would now be the following:
Does Hyprland have some built-in way to add virtual outputs directly during startup, or do I need to do some more-or-less hacky workaround like inserting a systemd-service adding an output before any graphical systemd-service that is autostarted?
PS: My guess is almost certainly correct, since I just tried disabling all autostart entries, and now Hyprland launches in systemd. The above question still stands, however.
