Title:
[Acer Aspire 5740] graphics card uses more power than needed when on
battery
Status in “xserver-xorg-video-ati” package in Ubuntu:
New
Bug description:
Binary package hint: xserver-xorg-video-radeon
By using powertop and reading the radeon/feature page on x.org I managed to
reduce the power consumption when on batery by about 4W on my laptop (from
about 22W to 18W). I just followed the recommendations on:
http://www.x.org/wiki/RadeonFeature
and did:
$ sudo -c sh 'echo "auto" > /sys/class/drm/card0/device/power_profile'
This solution, if it doesn't trigger problems for anyone, should be made
either the default or easily configurable through some file in /etc.
