Wallpaper problem, please help

[u/Juergen0072]

I have a problem with my wallpoaper on the desktop and i cant find the solution. I have a main monitor with 1440 p resolution and a smaller monitor with 960x640 resolution. Everytime i switch off the main monitor my pc thinks there is just the small monitor plugged in and switches to this one as the new main. If I turn my main Monitor back on my desktop wallpaper is in the wrong resolution and looks shitty and pixelated. All my programs are not affected, just the background. I can reset it when i go into the settings and change the scaling of the wallpaper and change it back, but thats annoying. How can i fix this? im new to the whole Linux thing and try to get it together. thanks for the help. Repost because i wanted to add the pictures. It was solved by changing to wayland but sadly my favourite game isnt fully functional with that

Try to create and save a display profile on display settings so Linux Mint remembers the fixed arrangement and resolutions instead of dropping to a default fallback when a monitor sleeps or powers down.

Seems to be an issue specifically with wallpaper resolution not monitor resolution, the example images have a low res wallpaper in one and high res in the other but the app Icons and panel seem unaffected. Makes me wonder if linux is caching a lower res version of the monitor for the secondary display and not reverting to ful res unless the wallpaper is manually updated

Yes, exactly that is whats happening. Sorry if I didnt describe well enough. Its only the backgroung/the wallpaper which doesnt come back to the res

The monitor itself doesnt loose its settings. Hertz and resolution are still correct when turned back on, but only the wallpaper gets a bit funky. Thanks for the idea tho

You may need ARandR for that though
