stumped - xorg edgers + 2.6.35-rc1 DRI fail

[hmmm]

I keep getting Permission denied whenever I try to enable dynpm:

echo dynpm > /sys/class/drm/card0/device/power_method

Same thing happens when trying to:

echo low > /sys/class/drm/card0/device/power_profile

try

sudo -i

and THEN your commands

[hmmm]

cheers, it worked - although i'm getting some intermittent flickering now.

Any idea why i had do go into sudo -i as opposed to having to running the command with just:

sudo echo dynpm > /sys/class/drm/card0/device/power_method

With this command, you just sudo-ed 'echo'. The redirect ('> /sys/...') is still done by shell (bash), which is not sudo-ed. I found once really interesting alternative, using tee:

echo dynpm | sudo tee /sys/class/drm/card0/device/power_method

The only side-effect is that "dynpm" string will be emitted to stdout too.

How well does the pm work now?

[pingufunkybeat]

sudo echo dynpm > /sys/class/drm/card0/device/power_method

You should put everything after 'sudo' in double quotes: ""
