Code: Select all
xbacklight -set X
Code: Select all
xbacklight -get
The XF86MonBrightnessDown (fn+some-key) isn't working either, although it may have been working earlier.
How can I further debug this issue?
Why are the extensions ["", "txt", "text"] "not allowed" for upload?
I tried stracing the xbacklight call, I'm including the output, but I can't make anything out of it.
Is there a way to do this via xrandr or is there a lower-level way?
