I have this Toshiba Tecra S5 with a fully up to dat KDE 3.5.9 and I found out the keyboard keys for controlling the screen brightness are not working.
When I press the keys a pop up appears in the panel left ot the clock and it shows the screen brightness as a percentage and I can change it.
But only the number changes, not the actual brightness.
Doing a search on this forum and other places I saw some indication that on other types of laptop the issue was particular to KDE's power management and not showing up in Gnome.
So I started an Ubuntu Live CD with and behold! I have brightness control.
Being curious I next started up with the Kubuntu Live CD and strange enough brightness control worked as well.
So It looks like this utility must have died during one of the (Kernel, Compiz?) updates done since install.
Or maybe the fact my install runs the Nvidia driver, not Vesa like the Live CD.
Does anyone have fresh ideas how to tackle this?
