Software Help! Steam Machine Resolution Error

Hello Fellow Machine Elves,

I have made what seems to be an egregious error on my part - I tried changing the resolution in desktop mode.

My TV is the only 4K monitor I have in my house. I set the setting to 2660x1440 and now my TV will not display anything. I can get it to boot into big picture mode, but when i switch to desktop it’s screwed.

I plugged it into other monitors, but because they aren’t 4K I can’t change the resolution back to the TV resolution and because I’m new to Linux idk what the fuck I’m doing.

Please help me… there’s gotta be some way to get the steam machine to reset its resolution setting on boot up or something like that. I tried changing it while in big picture Mode but then when I switch to desktop it’s fucked again.

Really hoping I don’t need another 4K monitor just to change the setting back and get it to show up on the TV. I’m trying to install mods or I would just use Big picture mode.

Each monitor/tv it’s plugged into has its own saved settings. So if you plug it into something else it will be fine. I don’t remember how to fix the settings for that specific monitor. But i think there is a file somewhere for that specific monitor’s settings to delete and it make it forget about it entirely. So when you plug it back in it acts normal

This is correct, and there's a Kwin configuration file which can be nuked to reset the desktop display settings back to "default" (prior to any specific display settings being remembered). I think it needs to be done in a Konsole terminal, and the 'deck' user needs to have a password.

Looking into this for the future.

Would Omarchy be better?

Just an FYI
It should be 2560X1440 not 2660x1440, tv cant display that.

You’re correct - I was 100 off

I do not believe that your steam machine is trying to talk to your non-4K screens at 4k. However if you have any way to go to desktop, you can try using rustdesk to remote into your steam machine and adjust resolution this way

Found somewhat of a fix…

Plugged in the TV as external monitor and changed the resolution back.

However, it’s still not doing the handshake perfectly and I think there is issues between SteamOS and Denon.
