Bug Description
Binary package hint: gnome-power-manager
I have a P35 Laptop and everytime after each restart the monitor starts to jitter and I have no brightness control also the problem shows up after five-ten minutes.
I can see the brightness control box but it seems frozen. The brighntess of the monitor goes endless up and down with no user control and the monitor jitters
the brightness control with "fn" button doesn't work.
only solution I found was to kill the gnome-power-manager - then I have control over brightness back and
the "fn" button works again
version installed: gnome power manager 2.20.0-0ubuntu3

BIG FAT ACK! I have here also a Samsung P35
I'm also the reporter of bug #136346 - g-p-m is still absolutely broken. The procedure looks like follows:
reboot apps/gnome- power-manager
gnome, log in
while true; do
killall gnome-power-manager
rm -rf ~/.gconf/
done
more issues:
- brightness control with Fn+Up or +Down only one level each time or g-p-m burns CPU with endless change events
seen with
dbus-monitor --system freedesktop/ Hal/devices/ platform_ i8042_i8042_ KBD_port_ logicaldev_ input; org.freedesktop .Hal.Device; member=Condition
signal sender=:1.3 -> dest=(null destination) path=/org/
interface=
string "ButtonPressed"
string "brightness-down"
..... repeat .....
and lshal -m i8042_i8042_ KBD_port_ logicaldev_ input condition ButtonPressed = brightness-up i8042_i8042_ KBD_port_ logicaldev_ input condition ButtonPressed = brightness-up
21:25:55.541: platform_
21:25:55.748: platform_
..... repeat .....
- dim display when idle when on battery causes brightness go down to 0% and back to 100%
(or flashes display and burns CPU)
