I’ve got a little disturbing problem here.
I’ve got a laptop with an C2D T8300 processor.
Up until a certain point - some two month away in the past, it always went perfectly to hibernate &c.
But then suddenly, after an update I can’t remember anymore I find myself stuck with the laptop going only to screen lock and screensaver instead of hibernating.
I’ve noticed that the Powermanagement section of KDE says that the CPU does not support frequency adjustments.
But I’ve got cpufreq running and the frequency is modulated just fine (down to 800MHz and back up to 2400).
Any ideas how to tackle this hibernation Issue (and the one with freq)?
It’s really annoying me as I need to have the laptop with me at university without having to take my power supply and loosing battery for startup & shutdown.
Sorry I’ve totally forgotten the system-info part.
I’m working on a OS 11.3 Kernel: 220.127.116.11-0.5-desktop
Desktop is KDE 4.4.4 (according to software management)
Installing Yast PowerManagement didn’t show anything new.
I still can’t go into hibernate and the Powermanagement in KDE still refuses to accept, that the CPU supports throttling/freq change.
Ok. I’ve updated KDE to 4.5 and it’s worse.
Altohugh it shows that DPMS & Runtime Consolekit support are availible, as well as two power states (Hibernation and standby) aer supported it’s still impossible to go to hibernation from KDE.
If I type “pm-hibernate” in console it immediately does what I want.
Furthermore now (with updated KDE) I can’t control the Brightness of the screen with the battery monitoring application anymore. So in overall KDE 4.5 seems to have worsened the situation.
