    .34 kernel w/Karmic Koala is running better than ever! I played Quake Live for a while, good times!
    I'm in no hurry to update to Lucid at this point.

    a new rc has been released for the kernel. Now at rc4

    http://www.phoronix.com/scan.php?pag...item&px=ODE0Nw

    apparently there have been some improvements including HDMI audio output for r700 cards

    Thanks for telling us.

    I expect Perry3D will incorporate it into his pre-compiled (Arch) repo shortly.

    A new branch in git.kernel has been created, it incorporates a reworking of the power management that makes PM more effective & work more the way it was meant to:

    Here is the kernel:

    http://git.kernel.org/?p=linux/kerne...on-testing-pm2

    Here is the patch:

    http://git.kernel.org/?p=linux/kerne...bb3ccb12eebbb6

    I have been using a kernel from Dave Airlied's site for some days, it works better than the main branch does re. PM.

    The guys on the Arch forum who are using the new PM kernel branch (previous post) are really happy.

    Pull the power plug from your notebook & it goes into the appropriate power mode, for example.

    I'm sure that there are exceptions as not all hardware has been tested by the dev's. But it is certainly looking great for the many at the moment.

    How can you check what is your current power mode?

    I'm using Arch, so I can't give you a step by step for Ubuntu. You need to have kernel .34, as that is where the PM is happening for the ATi GPUs. There is a better kernel branch re. PM, as mentioned in a previous post not too far back in this thread.

    This is what we are using in Arch:

    Re: ATi Open drivers are comming of age... :)

    Sorry, I think I didn't quite make myself understood.
    I have kernel 34 and all that set up. I get 6 states in my "dmesg | grep drm" output, but my question was with regards to that paritcular sentence:
    Pull the power plug from your notebook & it goes into the appropriate power mode, for example.
    When I unplug my cable my screen dims itself and my battery widget (KDE user here) pops and says that the the current Power Profile is Powersave. Does that mean that the GPU also goes into powersave mode? Or is there a command that outputs the currently active power mode?

    I also checked the Arch forum thread about ATI and I saw that some people there run "echo 2 > /sys/class/drm/card0/device/power_state" to change the power mode, but I don't have a power_state file or folder in that location or anywhere on my computer. Is it something that relates to the patches made for Arch?

    I also need to find out where to post issues with the open source driver. Using kernel .34 and xorg edgers has made a huge difference on my ThinkPad T500 when it's not docked, but when docked it becomes very hot again.

    From what I've read in the Arch forum, the GPU should go into power-save too.

    Have you tried using the kernel from Dave Airlied's site (linked above)? It is much better for PM than the Linus branch is currently.

    The kernel is basically vanilla with some extra PM development from a Red Hat guy & associated people. That command is kernel specific by the look of it.

    Perry3D has this link at the top of the OP of the ATi open-source driver thread on the Arch forum, where he requests people to report bugs to help the dev's making this software work for us all:

    Re: ATi Open drivers are comming of age... :)

    I just upgraded kernel .34, the other associated -git packages & also thought it was time I gave xorg-server 1.8 a try.

    It works fine, I had no need to add or edit anything in the new /etc/X11/xorg.conf.d

    Xorg-server 1.8 works fine with the open-source ATi drivers, but the closed ATi drivers require a little simple hacking & I'm not sure whether nVidia have released their new driver yet that will work with the forthcoming release of xorg-server. [Edit:] They have. /edit

    One of the new things that 1.8 does is remove the requirement of running HAL. I'll remove the daemon from my rc.conf on Arch & hopefully will still be able to use my keyboard & mouse. As previously I discovered that if I started using HAL again, I could dump the xorg.conf altogether.

    If I have any problem with HAL gone I'll add an edit to below.

    [Edit:] I just rebooted without the HAL daemon running & the machine is functioning fine so far. I just thought I'd delete HAL from the system but I found that at this stage there are too many packages that still require HAL, which is understandable I suppose seeing as xorg-server 1.8 hasn't been released yet.

    This is the result of trying to delete HAL from my system:

    handy ~ $ pdelete hal
    checking dependencies...
    error: failed to prepare transaction (could not satisfy dependencies)
    :: exo: requires hal>=0.5.13-2
    :: gnome-vfs: requires hal>=0.5.13
    :: gstreamer0.10-good-plugins: requires hal>=0.5.13
    :: handbrake: requires hal
    :: ogmrip: requires hal
    :: vlc: requires hal


    [Edit2:] nVidia's pre-release drivers support xorg-server 1.8:
