Description

It is bug in kernel maybe because it is the same in console (tty1, tty2, ...) If you stop moving the mouse or typing the backlight is dimmed to save power. If you don't like this, just uncheck the "Dim backlight when idle" in gnome-power-preferences. OK, but like I wrote before it happens during my typing or mouse moving. And it dim slow (in few second) for 1 minute approximately and then return (slowly) to normal brightness. It is really annoying. can you grab the out put from: killall gnome-power-manager gnome-power-manager --verbose --no-daemon Thanks. Created attachment 323901 [details]
log from gnome-power-manager
I have found something new. When it happens system is really busy. Xorg takes more then 20% CPU and many other utilities about 1% so CPU usage is more than 60-70% in time of dim. When I kill gnome-power-manager load is gone. So it can be problem of gnome-power-manager I suppose. This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Created attachment 326369 [details]
output of gnome-power-manager in no-deamon-mode and verbose
I have the same problem. Anything worked in Fedora 9, but now, with battery it's fading and a hight CPU usage like Pavel descriped. I ran: killall gnome-power-manager gnome-power-manager --verbose --no-daemon Output: see attachment After switching off power supply and only running with battery, the icon in the panel disappears so I ran System->... something linke energy administration (not using the English localization). Then gnome-power-manager --verbose --no-daemon suddenly crashes. Maybe, this is another hint to the problem… Reverting to fc9-source code would be the best ;-) Thomas works for me again… I believe this bug can be closed. I can confirm it. Now brightness change is really quick. Bug can be closed. I'm only curious what was solution (kernel/firmware update or changes in gnome-power-manager). Do you know it? No, i can't remember a gnome-power-manager update. As long as it works, it's OK.
