Version: (using KDE 4.2.4) Compiler: gcc 4.4.0 OS: Linux Installed from: Unspecified Linux I found some related bugs but I think none is exactly mine... I have my laptop configured to use powerdevil. I configured 3 energy profiles. When running on AC power I have Performance, when on battery I have powersave and when battery reaches 25% Xtreme Powersave. My performance profile is set to standby the display after 5 minutes and the other 2 profiles are set for 2 minutes. The other display options (suspend and power off) are disabled. When I unplug the AC and reconnect it everything works perfectly and does what it is configured to do. The problem is when I start up my computer, the performance profile is the default (for AC power). If I didn't switch to other power profile, the display doesn't standby after the 5 minutes. If I switch to other profile (the display standby) and then return again to the Performance profile everything works as it should be. Conclusion: the screen just turns off if I switch the power profile. If I do not switch, it doesn't turns off. If I set the display to standby with xset it works. I'm using archlinux x86_64 with catalyst 9.6. Since I remember I always had that problem. Thanks!
I have the same problems here with openSUSE 11.1 and the Factory packages for KDE4 (at the moment KDE 4.3 RC2 4.2.96)
So, that is a problem that continues with kde 4.3... It is not a big problem but it's boring!
Still exist in KDE 4.3.1 release 6 openSUSE 11.2 RC2.
Still there in 11.2 Final and KDE 4.3.3. My screen goes only off at the time specified in "systemsettings - display". It ignores the times that are specified in the powerdevil profiles.
Try to delete ~/.kde4 folder. You'll lose all your kde settings. Make a backup first if you want to reverte your changes. I did this some time ago and it solved the problem.
It's enough to delete those two powerdevil related config files at .kde4/share/config Works ;)
