Title:
Problem with brightness control on multi-monitor system
Status in “xorg” package in Ubuntu:
Expired
Bug description:
This problem only happens when I'm working with two monitors (my laptop
screen and another screen).
If I press the keyboard key "Brightness down", the screen resolution of one
of my monitors changes. If I press it again, the laptop's screen turns off.
I can restore my original configuration by going to 'System settings' ->
'Displays'
This problem doesn't happen when pressing "Brightness up" key.
If I change the brightness by going to 'System setting' -> 'Brightness
& Lock' (instead of using the keyboard keys), I don't get any
problems.
It seems to happen only when:
* Pressing the keyboard key to decrease brightness &
* Having multiple monitors
I have tried both nvidia closed source drivers and nouveau open source
drivers, and it happens with both of them. It even happens with Ubuntu
Live CD.
I have attached a video demonstrating the problem.
