I can physically swing around my monitor one right angle. On the console I can control orientation with the rotate_all "button" in /sys/devices/.../fbcon/. But xorg is not impressesed by that. Now I want to tell Xorg to start normally or rotated.
After getting several things right after Xorg -config (mouse and kbd now use libinput, card0 driver is "intel" not "modesetting") in /etc/X11/xorg.conf, I can start a simple window manager in X11.
xinit fvwm
I changed my xorg.conf to add a line:
Option "rotate" "right"
I was very happy for a few days: both tty and X can adapt to the tilted monitor. But now I swung back my screen to normal...and X starts wrong again! I don't want to check and (un)comment that option with every swing.
With...
xinit fvwm -- -screen r
... I was somehow able to choose a newly defined Xorg "Screen" with Identifier "r" and Monitor "rotated". But I lost it and I found out I still don't understand these screens and displays.
xrandr is good if I want to change the rotation.
From a rotate_all-ed tty, (with my tilted screen,) how can I configure xorg.conf so I can add "rotated" to my "xinit fvwm" command?
Now I just discover a line in section "serverlayout"...
Screen 0 "Screen0" 0 0
I don't have multihead; just one "head", occasionally tilted. How do I configure xorg.conf for that?
IT WAS A WRONG monitor Identifier ("DellRR" vs. "rotated" )....here is the xorg.conf, most of it. I have now two monitor and two screen sections for a rotated version.
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
Section "Monitor"
Identifier "rotated"
Option "rotate" "right"
EndSection
Section "Monitor"
Identifier "Monitor0"
EndSection
Section "Device"
Identifier "Card0"
Driver "intel"
#Driver "modesetting"
BusID "PCI:0:2:0"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
EndSection
Section "Screen"
Identifier "r"
