You might want to look into sudo dpkg-reconfigure -phigh xserver-xorg for resetting the xserver or (probably better look at the answer Mik suggested in the comments).Īdmins can drop scripts in /etc/X11/Xreset.d/ to run after the user logs out. As such, you would log off and everything would be back to normal, you would log on to your laptop, hit the launcher for the displays and enjoy life. You could thus a) add a reset script in /etc/X11/Xreset.d and b) make a script attached to a launcher that sets your dual external displays up. # The username of the user logging out is provided in the $USER environment # a display manager using /etc/X11/Xreset. The README file: # Scripts in this directory are executed as root when a user log out from You could use the Xreset directory ( Xreset.d) to paste a script that runs automatically when a user logs out. There is actually a little reset possiblity included in X11.

A bit tricky to answer, but here is a try. But it works.Ĭheck out this comment for a possible improvement to my solution (not tested myself).

Switch to the X server with Ctrl-alt-F7 before the sleep delay you set in the command above elapses.

Substitute LVDS1 by the output you want to modify, and -auto by whatever xrandr parameters you wanna use.

$sleep 5 xrandr -output LVDS1 -auto -d :0.

To get the names of connected screens (and assuming your X server is running on :0 ):

Open virtual terminal with Ctrl-alt-F1 and log in.

Otherwise you get an error like xrandr: Configure crtc 0 failed. So you have to chain a sleep command before your xrandr command to give you time to switch back to the X server with Ctlr-alt-F7 so the command is executed there. The key thing is that xrandr apparently only works on the currently focused display. I scoured pages of Google search results before coming upon the solution, so I thought I'd share. So same problem as you, I need to set the resolution from the TTY1 virtual terminal I can reach with Ctrl-alt-F1, but xrandr doesn't seem to work. Whenever I put my Lubuntu laptop to sleep when it's exclusively displaying on my TV and wake it up after having unplugged it, I end up with a black screen because the wrong resolution is assigned.
