Howdy,
I've got an issue where the layout and mode of my displays resets to the default at every login. This is despite me setting up the monitors in the TDE Control Center, both locally as my user and globally as root, creating an X config using the NVIDIA X Server Settings, and having no such issue previously when I was still using KDE Plasma.
I'm using the latest NVIDIA proprietary drivers on EndeavourOS, with a 1920x1080@60hz display on DP-1 and a 3440x1440@144hz display on DP-2. The ultrawide 1440p display is on the right slightly above the smaller one, but Trinity and TDM both repeatedly place them in the opposite arrangement with the smaller monitor as the default, sitting on the top right corner of the larger one. Both displays default to 60hz at login.
I've also tried enabling "Automatically apply profile on startup" and creating a profile, but when trying to reload it, X spits out an error "xrandr: cannot find mode 3440x1440". I don't get any such error when logging on, only when trying to load it manually from control center, which makes me think it's not even trying. I have not tested using xrandr manually from the command line.
How do I get Trinity to remember my monitor layout correctly? Is this a known issue?
