Problem with display resolution on linux

[Isbjoern]

I got a dual screen setup which messes up games for my sometimes. When I start the game I can't see any control at also, just a messy room. Looking in the folder ~/.config/unity3d/Miman/Else Heartbreak I can change prefs file to the correct setting from 2704 x 1280 to 1680 x 1050 but starting the game restores it. Seems lika problem with not being able to set full screen on one screen. The games take up the total area but only displays it on one screen. Trying to change from fullscreen to windowed by changing the preferense is likewise ignored.

My players log

Hmm, not sure how to solve this... Do you have an idea what I could do to help you out?

[Isbjoern]

I managed a work around by turning of the secondary monitor in settings long enough to change the settings to windowed mode.

I am having a similar problem but only one my one screen. I clicked on an unsupported screen resolution and now I cannot access any menu to change it back. I am on Linux. Do you have any recommendations on how to resize the resolution? I have tried the -win and -w commands to no avail.
