It's been a while since I've needed to use xrandr. I remember being able to just use -s# to specify which configuration you wanted to apply for example if I had:
CRT1 connected 1400x1050+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1600x1200 60.0 + 1400x1050 60.0* 1280x1024 60.0 47.0 43.0 1440x900 59.9 1280x960 60.0 1280x800 60.0 1152x864 60.0 47.0 43.0 1280x768 59.9 56.0 1280x720 60.0 50.0 1024x768 60.0 43.5 800x600 60.3 56.2 47.0 720x480 60.0 640x480 60.0
And I wanted to set the screen resolution to 1024x768_60.00 I would specify
xrandr -s9 and the 9th configuration would be applied. However, this does not seem to work anymore. How do I apply one of the printed resolutions?
