Below is my /etc/X11/xorg.conf.d/1-fbdev.conf.

/etc/X11/xorg.conf.d/1-fbdev.conf

Section "Device"
  Identifier "LCD"
  Driver "fbdev"
  Option "fbdev" "/dev/fb0"
  Option "Rotate" "UD"
EndSection

I would like to change the Rotate values ​​in real time (without restarting the X)

ex)Option "Rotate" "CW"

How do I apply during the execution X by changing the settings of the xf86-video-fbdev in real time?

    have you read the xrandr man page? there are also several GUI front-ends to xrandr, including lxrandr for lxde, grandr for gnome, and arandr.

  • i don't use xrandr. i know "xrandr -o left". I know the xf86-input-video does not support rotation using xrandr.

  • Have you found a solution? My idea is to modify xorg.conf and restart lightdm with a script... Not very proper but the only idea I have...

    Did you try xrandr --output LCD --rotate left as well?
