Bug Description

Binary package hint: xserver-xorg-video-ati

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/Xorg.0.log:

The same problem exists with other power saving options:

# cat /etc/X11/xorg.conf
Section "Device"
Identifier "Configured Video Device"
Option "DynamicPM" "on"
Option "ClockGating" "on"
Option "ForceLowPowerMode" "on"
EndSection

and in /var/log/Xorg.0.log:

(WW) RADEON(0): Option "DynamicPM" is not used
(WW) RADEON(0): Option "ClockGating" is not used
(WW) RADEON(0): Option "ForceLowPowerMode" is not used

I think you also need a 2.6.34 kernel.

That option in xorg.conf is only used if KMS is not in use, and it is by default. You can add radeon.modeset=0 to your boot stanza if you want to use it through xorg.conf. Like madbiologist said, dynpm is only available with KMS on a 2.6.34 kernel, but you can use the dynclks module parameter to enable a bit more power savings.

This bug was fixed in the package xserver-xorg-video-ati - 1:6.12.192-2ubuntu2

---------------
xserver-xorg-video-ati (1:6.12.192-2ubuntu2) lucid; urgency=low

  * Add xserver-xorg-video-ati-6.12.192: Document that several
    power management configuration options do not work with KMS
    and kernel versions less than 2.6.34.
