About ATI drivers in Lucid

[Speed_arg]

When I booted Alpha 3 live cd, compiz was enabled with some effects, and rendering worked fine, unlikely previous versions which without drivers would suck and not enable you to use compiz.

Now my question is, does lucid bring ATI drivers out of the box? Or what? I read about the nouveau stuff, but thats for NVIDIA only, isn't it?

The open-source driver for ATI is maturing, that's all.

If only it had gpu power management support.. The lack of it sucks for laptop users.

My battery is broken anyways (36.9% capacity left - 20 min) so I don't mind, I have to use the power cable anyways. The only problem for me is a slightly warmer laptop.

you could use some of the pm options in /etc/X11/xorg.conf, eg.

Section "Device"
        Driver          "radeon"
        Identifier      "Configured Video Device"

        Option          "ClockGating"           "on"
        Option          "DynamicPM"             "on"
        Option          "ForceLowPowerMode"     "on"
EndSection

a initial xorg.conf can be made with
sudo dpkg-reconfigure -phigh xserver-xorg
or so

Do these options work with KMS enabled? Also, do they make the fan go as slow as fglrx does?

I'm afraid not, but thanks anyway.

i used this options some month ago with karmic and xorg-edgers without kms.

proper kms power management should come with 2.6.34. just wait another week for rc1

And did the options help? Was there a performance penalty? I guess for normal desktop (actually laptop ) use it didn't make any difference?

Edit: Alas, it's not working for me:

[    0.155408] (WW) RADEON(0): Option "ClockGating" is not used
[    0.155422] (WW) RADEON(0): Option "DynamicPM" is not used
[    0.155432] (WW) RADEON(0): Option "ForceLowPowerMode" is not used

Guess I'll have to wait for the 2.6.34 kernel...

The worst thing is that the laptop goes quickly hot and loud - thanks to its fans. I hope 2.6.34 kernel will fix that issue.
