Good day everyone,
as mentioned I'm using my Thinkpad L530 running Ubuntu Gnome 13.04 as of late. I have two basic problems at the moment:
Toggeling the screen brightness with fn+F8 /fn+F9 only shows 'toggle brightness'-popup and a bar of the actual brightness for a few seconds but tapping fn+8/9 does not actually increase/decrease the brightness
Can anyone help me with this?
