Hello,
some days ago I changed the display resolution to the from deepin recommended value of 1920 x 1200, but this is for my monitor out of range and the GUI doesn´t work any more. With Ctrl+Alt+F2 I can open a terminal session, but from there I wasn´t able to change the resolution for the X-Server. I tried already xrandr, but this is only for the current session (and I have a terminal session). I also searched a lot in the web, but i didn´t found a solution that worked for me.

So can please anyone help me for my problem and tell me how I can change the resolution for the X-Server in a terminal session?
THX
