After removing kpowersave, can't change screen brightness with Fn keys
Last modified: 2009-05-26 09:24:24 EDT
Description of problem:
After the recent upgrade to 4.2 in F10, I had kpowersave, guidance-power-manager as well as the new powerdevil framework for managing the laptop battery. I removed kpowersave and guidance-power-manager and switched to powerdevil.
My laptop is a ThinkPad X200 with Intel graphics.
After removing kpowersave, however, my Fn+brightness keys stopped working. I can change the brightness from the battery plasmoid. tpb is also installed and it shows its brightness bar as well when the setting is changed from powerdevil.
Interesting, we've other reports from thinkpad users reporting Tn+brightness keys have *never* worked:
Maybe it was kpowersave's use-of/reliance on acpid for some functions? (newer apps like guidance and powerdevil use hal exclusively)
Keep this open, bump upstream or WONTFIX?
Going to close this as UPSTREAM. Since there is little the KDE-SIG can do
about this and other multimedia/laptop button issues we have to wait for
upstream to address this.
