During updates overtime I lost the abillity to use the Fn-F5 and Fn-F6 for brigtnes control and my WiFi connection.
Not a big deal cause I could find the settings in Mixer and configurations with my eyes closed, the network cable is mostly only 2 inches away.
I still had the
as backup in the Grub startup menu.
Needing the wireless on a club meeting I fired up the 2.6 version for checking,
Lo and behold, Fn and wireless where instantly working again.
I think I leave it on the older kernel for a while
