Bug Description
Binary package hint: xserver-
I am trying to use the DynamicPM option to increase running time while on battery power. I created a xorg.conf file with the following content:
# cat /etc/X11/xorg.conf
Section "Device"
Identifier "Configured Video Device"
Option "DynamicPM" "on"
EndSection
Unfortunately, this option does not seem to be useful because I see the following warning in /var/log/
