[Bug 219818] Re: kpowersave resumes to wrong screen brighgness after blanking

[Sami Mäkinen]

Yes, the issue is still present in 8.10, though behavior is a bit
different.

In current up to date Kubuntu 8.10 with KDE 4.1, I can start kpowersave,
and leave it running, but when I reboot it is automatically replaced by
Guidance power management.

Observations:

* Go to system settings > Display, and set power management on and set all three options to 1 min. Wait for 1 min.
-> Screen shuts down, then after a few seconds blinks back on to normal visibility, and then goes black but the backlight remains on. Also the mouse cursor remains visible, although the screen is otherwise completely black. Upon moving the mouse, system restores screen. Backlight is on a level which is neither the minimum or maximum brightness, but something in between. This brightness level is independent of the brightness slider setting in Guidance.

* Quit Guidance. Go to system settings > Display, and set power management on, and set standby after 1 min, suspend after 2 mins and power off after 3 mins. Wait for 3 mins.
-> after 1 min same as above happens (screen goes fully off, then after a few seconds blinks on, and then goes black but with backlight on and mouse cursor visible).
-> after 2 mins nothing happens.
-> after 3 mins screen goes fully off, and does not come back on.

* Now after rebooting Guidance always starts up, even if a quit it just
prior to rebooting. It does not ask whether it should be automatically
started, like KPowerSave did.

* The "Hold"-button still works the same way it did in 8.04 / KDE 3 as
well as the preinstalled Windows Vista, i.e. turns off both display and
touch screen after a few seconds of delay.
