I've been trying to get my Toshiba Satellite 870 set up properly and I'm stumped trying to get the monitor brightness control working.
It has a "FN" shift key for the function keys so that it should, for example, reduce the brightness if I press FN+F2. Some key combinations work for example FN+F9 reduces the volume.
I have checked with xev in a terminal and, while pressing F9 gives keycode 75 without the FN key, it gives keycode 122 with the FN key.
FN+F2 should give keycode 232 according to xmodmap -pk but it gives no key event. Out of the 12 function keys only 6 work with the FN key. The others behave correctly.
I have tried a number of alternative keyboard layout from PCC but they all give the same result.
It is not a hardware problem problem as these keys all work in another distro and in Windows.
There is another thread here where this problem was solved by changing to the pae kernel. However that didn't work for me and moreover it stopped the wifi working!
So what am I missing? Is there a file somewhere that gives the key codes that each key or combination should produce?
Im running PCLinuxOS KDE 2012.8 fully updated and using kernel 3.2.18-pclos2.bfs.
Any suggestions would be appreciated.
