    Good day!

    Do we have any progress on this issue? Is this a workaround that users can perform in the meantime as to avoid the terrible maximize lag? (It's quite frustrating)
    yes, install an unbroken X server with fedora_dont_backfill_bg_none.patch

    X flies afterwards.

    There are patched debs for kubuntu and an ebuild for gentoo. For the others:

    google

      ++

      works for me

      besides that:

      when using it with catalyst 9.10 (from ubuntu) it's rockstable, feature-rich (no video-lagging, corruption, etc. with composited desktop) and suspend & VT-switching support

      still problems:

      * lack of support for fully peemptible kernel & rcu
      * lack of support for other slab allocators (e.g. slqb)
      ---> it works somehow with them and the installation is prevented by the installer

        Thanks, however Googling for this "ubuntu fedora_dont_backfill_bg_none.patch" results in only 4 hits. :-( -- (those of which don't actually explain how to do it)

        I have no experience with installing a non-default X server. Could someone please reference a link explaining how to workaround this issue?

        Thanks!

          ArchLinux (http://aur.archlinux.org/packages.php?ID=26687) seems to provide the correct files, but I'm not confident in the procedure.

          (i.e. If it requires compiling from source, we should use checkinstall so that the change can be reverted when the official change comes down the pipe, and do we need to re-install anything after adding the modified X-server?)

            openSUSE Factory xserver-no-backfill packages

            For openSUSE Factory users I have built xserver packages including the respective no-backfill patch: http://download.opensuse.org/reposit...nSUSE_Factory/

            Remember that the kernel version in Factory is 2.6.31, so you need the Catalyst 9.10 beta driver from Ubuntu 9.10, which you can install with the help of this script written by kano:
            Code:
            #!/bin/sh
            cd /usr/src
            wget -N http://www2.ati.com/drivers/linux/ati-driver-installer-9-8-x86.x86_64.run
            wget -N http://archive.ubuntu.com/ubuntu/pool/restricted/f/fglrx-installer/fglrx-installer_8.660.orig.tar.gz
            DIR_OLD=fglrx.old
            DIR_NEW=fglrx.new
            rm -rf "$DIR_OLD" "$DIR_NEW"
            mkdir "$DIR_OLD" "$DIR_NEW"
            sh ati-driver-installer-9-8-x86.x86_64.run --extract "$DIR_OLD"
            tar -C "$DIR_NEW" -zvxf fglrx-installer_8.660.orig.tar.gz
            cp "$DIR_OLD"/* "$DIR_NEW"
            cp -r "$DIR_OLD"/setup.data "$DIR_NEW"
            cd "$DIR_NEW"
            wget -qO- "http://phorogit.com/index.php?p=fglrx-packaging.git&dl=targz"|tar zxv
            mv -v fglrx-packaging packages
            rm -rf packages/ArchLinux
            mkdir common
            mv -v etc lib opt usr common
            cp -r ../"$DIR_OLD"/packages/ATI packages
            ./ati-installer.sh 8.66 --install
            I also opened a feature request to have these packages in a more prominent place: https://features.opensuse.org/307845.

            When I find time, I will provide versions for openSUSE 11.1 as well.

              I've found a solution for the lagginess. Our problem is described in this bug:
              https://bugs.launchpad.net/ubuntu/+s...6?comments=all

              In the comments there is a patch for X that was removed to prevent graphics corruption mostly for Intel chips. Re-applying that patch solved my problem.

              Someone set up a repo with the patched X, so all you have to do is add it, do an update, and restart!
