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?

It seems that the brightness control functionality issue is with the nVidia proprietary drivers... unfortunately those are proprietary and it might take some time before it's fixed, if at all:… However you can look at nVidia's website for the latest drivers and see if they are fixed in the latest blob package: – Richard Sep 19 '13 at 21:07
