If I have only the internal monitor (LVDS1) with an xrandr -o left command. Now I want to attach a second monitor, say to HDMI1. Then I'd like to rotate only the internal monitor, but not the external one. I tried the following (with no external attached though, since I am mobile currently), but that does not do anything:

xrandr --output LVDS1 -o left

How can I rotate only one monitor?

I do need some command line, since I want to put this into a script.

are you using an nvidia graphics card? –  tomodachi Jul 31 '12 at 23:14
    
No, I use the Intel Card in the i5. –  queueoverflow Aug 2 '12 at 12:01

The trick is to use the newer --rotate instead of -o which needs to be used with a --output argument:

xrandr --output "$internal" --rotate "$xrandr_rotation"

Examples

xrandr --output LVDS1 --rotate left
xrandr --output LVDS1 --rotate right
xrandr --output LVDS1 --rotate normal
xrandr --output LVDS1 --rotate inverted

and you can string these together for -- like so: xrandr --output VGA1 --auto --output HDMI2 --auto --right-of VGA1 or for |- like so: xrandr --output VGA1 --auto --pos 0x0 --rotate left --output HDMI2 --auto --pos 1200x300 –  Stefan Schmiedl May 20 at 7:47

If you open the System Settings and choose Displays there, you can select the monitor to rotate, and choose which rotation to use, for each individual monitor you wish to rotate.

This is nice, but not scriptable. So I need something which I can invoke from the command line. –  queueoverflow Jul 3 '12 at 14:11
