X blank screen

[osmukhin]

I've changed resolution on pinebook pro debian to 1024x768.
The screen become black.
How can I return resolution 1920x1080 from the CLI?

[tophneal]

xrandr -q
xrandr -s [resolution]

Once your resolution is restored, try using the Tweak app to set scaling, instead.

Thank you very much!
It' s what I search for.
(One thing to add before this commands:
export DISPLAY=:0.0
Otherwise "Can't open display".)

Sorry, I just copied the other person's solution, (which worked for them), to the Wiki. I've never experienced this problem.

You can try something like this, but I don't make any guarentees;

• Using a text console, (Control-Alt-F1), login with your normal user ID
  
• Edit the file "nano ~/.config/monitors.xml"
  
• Change the "width" value to "1920"
  
• Change the "height" value to "1080"
  
• If there is more than one monitor configuration listed, edit that one too.
  
• Be careful to make no other changes. If needed exit without saving and re-edit.
  
• Save the file and exit.
  
• If you are still loggied in via the GUI, you will have to reboot using "sudo shutdown -r now".
  
• After the reboot, you should be able to login to the GUI login and have the resolution back to normal.
  

Let us know if that worked, so I can update the Wiki.
