[QUESTION] Changing brightness of virtual screen

josephbuchma opened this issue 8 years ago · 4 comments

I created multiple virtual monitors, and when I change brightness xrandr --output 'HDMI1~1' --brightness 0.9 it disables output completely (whole screen turns black). Is it possible to change brightness of virtual screen ?

You cannot change anything about the virtual screens because they don't actually exist.

@phillipberndt thank's for fast response. Maybe you know if it possible to change brightness of some area on the screen using available tools (i'm on Ubuntu)? I have a monitor with uneven screen brightness and want to compensate it somehow.

Hmm.. Compiz (the compositor) can do a fair amount of magic when it comes to multi monitor emulation, maybe there is a plugin for this as well.

thanks @phillipberndt, I'll check it out. I already spent more than hour searching for the solution. It feels like I am the only person on Earth facing such problem.
