Title:
Poor battery life on UL30VT due to NVidia graphics active
Status in “linux” package in Ubuntu:
Expired
Bug description:
The ASUS UL30VT has two graphics cards like many modern laptops.
Unfortunately, the higher powered NVidia g210m is active by default,
chewing through an additional 4 watts of power and reducing battery
life by a few hours.
This will be a non-issue when Bug #312756 is fixed (graphics card hot
switch). In the interim, laptop users need some way of disabling high
powered graphics cards to conserve power. This is not possible in the
ASUS UL30VT.
A partial solution is available at
http://ubuntuforums.org/showthread.php?t=1366605 which provides a
package that disables the NVidia card. Unfortunately, the card is
reactivated when resuming from suspend and not enabled by default on
boot.
