I have a computer with ONLY ONE MONITOR - these are the specs:

   1680x1050_60.00   60.0  

VIRTUAL1 disconnected (normal left inverted right x axis y axis)

This works (changes the resolution), then I do

$ sudo reboot

and on start I get the previous resolution and the following message

No se pudo aplicar la configuración almacenada para los monitores
none of the selected modes were compatible with the possible modes:

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • also, does anyone think this problem could go away if I change the graphic card to a better one? Thanks!!! – Tabula Rasa Oct 6 '15 at 13:45
  • Intel core 2 duo graphics are a nightmare to get as you want them. I actually had almost exactly the same specs as you and I had to use xrandr - I also got this error. If you get an NVidia card - such as a Geforce 210 (£20), you'll find it loads easier to set your desired resolution – TellMeWhy Oct 7 '15 at 12:47

You need to add the xrandr configurations to a startup file, so that you'll get your desired resolution upon reboot/startup:

  • Create a bash script, xrandr.sh for example, and place your xrandr commands into it:
#!/bin/bash
xrandr --newmode "1680x1050_60.00"  146.25  1680 1784 1960 2240  1050 1053 1059 1089 -hsync +vsync
xrandr --addmode VGA1 1680x1050_60.00 
xrandr --output VGA1 --mode 1680x1050_60.00
  • Make the script executable with chmod +x xrandr.sh

  • Search for "Startup Applications" in the dash, run it, and add the script as a startup application.

The commands will now run every time you log into your account.

  • hi, DevRobot. Thanks for answering so promptly. I tried that solution and it works. I don't have to copy/paste the commands every time I turn the computer on. But I humbly believe there must be a way of achieving this without having the computer trying something and failing and trying it again. Here's a screenshot o how it looks on startup and the xrandr output !Screenshot . Isn't there a better way of having your optimal and desired screen resolution? Thanks!!! – Tabula Rasa Oct 6 '15 at 12:53
  • @TabulaRasa first of all, did you use cvt 1680 1050 to determine the exact newmode line required? – TellMeWhy Oct 6 '15 at 14:43
  • @TabulaRasa this is one of the solutions for getting a permanent xrandr configuration - but if you have an NVidia card, you can install the required driver and get a better solution – TellMeWhy Oct 7 '15 at 12:28
  • The arandr pacakage has a an obscure but nice command line utility also called unxrandr which can get the xrandr command to make your current display and then put that in the script and autostart it. – ianorlin Oct 10 '15 at 16:37
