Hi,

I have a Lenovo W500 thinkpad. When I use fglrx in Xorg my laptop only consumes
15-16W, but fglrx is so unstable that it crashes on logout, and I despise using
it.

When I use the OPENSUSE 11.1 radeonhd driver, I have much improved stability
(although no acceleration), but power usage also jumps to 35W! I have tried
xorg-x11-driver-video-radeonhd-1.2.4_121202_4e89726-1.5 and even the latest
xf86-video-radeonhd git version but they all behave the same.

Interestingly, when I'm not in X I also have high power usage, whether or not
fglrx or radeon modules are loaded or not. I suppose the graphics card is not
running in low power modes without fglrx. The only way I can get low power
usage is through using fglrx in an Xorg session...

I have even tried the radeontool tip mentioned here -
http://www.phoronix.com/forums/showthread.php?t=6522 - but it made no
difference.

Any ideas would be appreciated!

cheers
Niel
