  • radeon 9800 and open source driver, working with some probs..

    Hi everyone
    i finally got compiz working with my ati radeon 9800 card by using the open source driver, every experiment with fglrx was a failure moreover most of the time they lock me out of X even with metacity or just give no DRI.

    With the open source drivers and no compositor they do work great, i have around 3600fps with my card, but if i turn on compiz the fps drop to 1400 with a strange behaviour:

    glxgears works full speed for a second, then stops, then again full speed, then stops, then again full speed.
    and so on..
    Actually it is working in an on-off way, and i don't know how to fix it..
    If someone has more experience to give out some hints i'd gladly try
    Here is my xorg.conf
    Code:
    # xorg.conf (xorg X Window System server configuration file)
    #
    # This file was generated by dexconf, the Debian X Configuration tool, using
    # values from the debconf database.
    #
    # Edit this file with caution, and see the xorg.conf manual page.
    # (Type "man xorg.conf" at the shell prompt.)
    #
    # This file is automatically updated on xserver-xorg package upgrades *only*
    # if it has not been modified since the last upgrade of the xserver-xorg
    # package.
    #
    # If you have edited this file but would like it to be automatically updated
    # again, run the following command:
    #   sudo dpkg-reconfigure -phigh xserver-xorg
