Hello.
Kubuntu 9.10/10.04
Desktop, ASUS P5QL/EPU Nvidia 9400 GT + LCD Philips 190x6
In the morning I cannot use my desktop cause screen backlight is turned off.
I tried turn off screensavers (system settings/display) and power managment functions (system settings/power managment).
It's not helping
Computer runs screensaver. In the morning I cannot use it cause no backlight.
However if I run sleep and wake up in a 5 min everything is ok.
I've tried google for commands which turn/off set/get brightness of screen - no one working for me.
1. How to turn off display power management ?
2. or maybe there is a reliable way to fix this ?
3. or how do I reproduce the bug (i dont want to wait morning each time)
4. Found interesting thing "--quirk-reset-brightness" in /usr/lib/pm-utils/video-quirks ? How to test it ?
