Hi everyone.
I installed Arch on my HP EliteBook 8460p laptop and have a good time with it.
However after a hang of xfce (the mouse was still working but the screen hang), I cannot control my brightness by Fn+F10 anymore.
The brightness progress bar pop up but it doesn't change when I press buttons so now I have to work around with commandline but it's so unconvenient.
Any advice? I looked for errors in many xfce config files, change brightness value (I restored it after that) but nothing seem to work. Thanks for your replys.

Have you tried some kernel parameters?

I have lost function-key backlight control after a kernel upgrade and had to add one to regain it.
Alternatively just use a keybinding for whatever command you are using (xbacklight?).

Yes, I am using xbacklight. Oh, maybe it's also time when I upgraded kernel. I rebooted laptop. Let me try.

I added parameters to kernel but no lucky here. I switch to KDE and brightness control works perfectly, so it's not a problem of kernel

Check out the note on the wiki page:
https://wiki.archlinux.org/index.php/Backlight#Overview
Could be related to the problem described there.

Oh, I almost give up but eventually I find out the reason. Someone turned off checkbox "Handle display brightness keys" in Xfce Power Manager . Thanks teateawhy very much for the advice, I never ever think about this area

Lenovo G505s. Same issue and resolved by enabling "Handle display brightness keys" in Xfce Power Manager. Now Fn+F11 and Fn+F12 works properly .
