Title:
Screen brightness adjustment delay in Xorg sessions only
Status in mutter package in Ubuntu:
Won't Fix
Status in xorg-server package in Ubuntu:
Won't Fix
Bug description:
Every time I adjust my laptop's screen brightness using the dedicated
brightness keys, there is a substantial delay between when I press the
button and the screen adjusts. Sometimes it even "twitches" and
decreasing the brightness by tapping the button two times will quickly
drop the brightness all the way to the lowest setting after the delay
takes place. I've noticed the issue in the default Ubuntu session and
in my current vanilla gnome-session. It also doesn't matter which
extensions I have installed. The keys work flawlessly in Windows so it
isn't a hardware issue. I have been meaning to report this for a while
and have just never gotten around to it until just now.
