On my Thinkpad T580 laptop, the Fn+F5 and Fn+F6 shortcut keys manually control screen brightness. These shortcuts function as expected with KDE and Xfce but not TDE. No special configuration is needed.
I find nothing that helps in kcontrol or tdepowersave. I found a thread in this list discussing the issue but with no simple solution.
What is needed to have TDE support these shortcuts to "just work" like with KDE and Xfce?
Thanks.
