Rotating one screen with xinerama in a multihead setup

rated 0 times [ 1] [ 0] / answers: 1 / hits: 2262 / 2 Years ago, thu, december 16, 2021, 12:18:37

I have a dual-head setup: a "main" screen at 1920X1080, and a "secondary" screen to the right of it, rotated at 90 degrees counter-clockwise. Until Friday (26.10.2012), everything was working fine, however on that day an update has caused the rotation settings in xorg.conf to be ignored.

Specifically, I had used the rotation attribute (like in this question). Also, since I have Xinerama enabled, I don't have access to xrandr and the corresponding GUI settings (due to this bug, I think).

What should I change in my xorg.conf to have the second screen rotated again?

Here's my current xorg.conf (the third screen is a monitor built in into the laptop, disabled since my video card can only support 2 outputs). I haven't removed any comments to provide a possible forensic trace.

Well, in the end, the answer was stupidly simple.

cp /etc/X11/xorg.conf ~/xorg.backup

sudo rm /etc/X11/xorg.conf

sudo shutdown -r now

And, after this, I can change the screen layout normally.
