no mobility powerset

[devstefano]

Binary package hint: xserver-xorg-video-radeonhd

Hi I have this problem, I have an asus F3jp with Ati Radeon Mobility x1700.
I install ubuntu 9.04, but I can't install catalyst 9.3 cause xorg1.6 work only with catalyst 9.4.

Catalyst 9.4 is only for now HD video card and so don't support my video card.

There isn't problem with GUI or Compiz, RadeonHD open drive don't have powerset! so my video card work full power always!
This make my battery life short and make my laptop very noisy (cause full speed fan) and HOT!! VERY HOT!.

Anybody know how set the power of my video card low? I don't need all video card power. For youtube and some film i think minimum power is enought!

On ati driver was powerset...

Sorry my English!

Both the -ati/-radeon driver (which is the default supported driver for your card in Ubuntu 9.04) and the -radeonhd driver have got power management support in their development versions. So this will be available in Ubuntu 9.10.

For now, you can test out latest development versions from my PPA https://launchpad.net/~tormodvolden/+archive/ppa
See the radeon and radeonhd man pages for which options to try out.

Any particular reason you are using the -radeonhd driver? Please try the -ati driver to see if it is better.

Hi sda1986,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

I just reinstall Ubuntu on my asus F3jp and delete all video driver but radeon driver.

Attachment: lspci-vvnn \ Xorg.0.log

Where i can find man online of new beta driver?

Thanks.

I install new driver and i read the man, i change xorg.conf and i add lspci-vvnn and xorg.0.log.

The video card is less hot but the cooling fan work full speed all time, and the video card is hotter than windows when in lowpower.

How i can watch the frequency of video GPU and video Memory for understand if the video card have minimum frequency?

Thanks.

Now I try Ati RadeonHD

sda@f3jp:~$ grep "Clock" /var/log/Xorg.0.log
(II) RADEONHD(0): Default Engine Clock: 460000
(II) RADEONHD(0): Default Memory Clock: 400000

(II) RADEONHD(0): Attempting to set Engine Clock to 230000
(II) RADEONHD(0): Current Engine Clock: 229500

It look like GPU engine clock go down to 229,5Mhz, but no way for undestand the Memory clock.
but 229.5 is not the lowest clock my GPU can use...

Thanks.

I find Low power core and memory speed.

High Power: GPU 460 Memory: 400
Medium Power: GPU ??? Memory: ???
Low Power: GPU 128 Memory: 135

I read this frequency from windows xp pro sp3 with catalyst 9.3.

[devstefano (devstefano)]

Any news? what part of source code manage power of the video? maybe i can read and try find a solution.

Stefano, you may be interested in http://www.botchco.com/agd5f/?p=45 and discussions on http://phoronix.com/forums/forumdisplay.php?f=43

As you can see from the blog, the power management is currently in the radeon driver. On the longer term, the power management will move to the kernel (under the drivers/gpu tree).

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.

there is no -radeonhd in the archive anymore, closing the bugs.
