    Has there been any improvement with latest Catalyst driver (11.5)?

    In one way it seems to be possible. Like unloading the fglrx module is usally no big deal when X is down. But my attempts to switch from oss kms to fglrx where never successfull. I had the code in my script but disabled it (it works for nouveau -> nvidia). From oss without kms to fglrx the success rate was a bit better but not great. Just stop X, rmmod fglrx, switch those libs, run maybe ldconfig and move the xorg.conf away, then start X again.

    If they ever implement switching between fglrx and mesa without restarting X it would be interesting even with a computer with just one Radeon card, to use the r600g driver for most of the time and only switch to fglrx when running an app that the mesa driver can not handle.

    You're right, all I had to do was restart X.
    Thanks!

    Sure, r600g xv is broken (Debian Sid), but the X11 output (in MPlayer) of r600g is way faster than Catalyst xv anyway so why bother until this gets fixed the right way.

    Those are just tiny mesa vs fglrx switch tools. It is impossible that they do something usefull when you have got amd igp + dedicated. They could be used to switch between intel + amd gfx. But most likely you have to select the card you want to use in the bios.

    Then it's broken in that particular build, but it's there in the fglrx 8.84 stream.

    As mentioned this morning when AMD provided Canonical with a Catalyst 11.4 driver pre-release for proprietary Radeon / FirePro support under Ubuntu 11.04, there's more than just support for Linux 2.6.38 kernel and X.Org Server 1.10. This Linux driver update also provides support for AMD PowerXpress with dual-GPU notebooks...

    I just came across this message on Ubuntu Forums:

    Hi all,

    A new fglrx driver (2:8.840-0ubuntu1) is now available in Natty and it
    finally works with the new xserver. There are still a few issues whose
    fixes should land after Beta 1 is released:

    [...]

    Note: despite what the relevant article from Phoronix claims, the driver
    doesn't support AMD's PowerXpress.
    LOL

    Those scripts just disable or enable the files that fglrx replaced with the standard installer. I am not sure if that's something i have to like or not, for a distro like U >= 10.04 it is useless as
    Code:
    update-alternatives --config gl_conf
    update-initramfs -utk all
    ldconfig
    and changeing/removeing the xorg.conf would even allow to switch to nvidia driver. Basically those things should be done with update-alternatives on a debian/ubuntu system, it is just a hack that you don't need to remove the complete driver in order to use the onboard chip.
