I have been trying to get this to work using xrandr and ssl, and now the brightness as mentioned in this post
/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1/intel_backlight#
xrandr works if I login via ssh and run, but sending the command via ssh does not work ( think xorg not started in that mechanism )
I am using teguar tp2945 displays, perhaps not compatible with the instructions ?
Code: Select all
root@kiosk:/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1/intel_backlight# ls -l
