I suppose the key feature above is disabled unsupported XAA render acceleration in the case of old driver (6.12.2 build 2) and enabled EXA acceleration in the case of the newest driver (20091010_git).

I found simpler solution of the problem described in that thread:

1. I downgraded the system to default xf86-video-ati 6.12.2 build 2 driver.

2. I generated xorg.conf.new with X -configure command.

3. I copied it from /root to /etc/X11 directory and renamed to xorg.conf.

4. I added Option "AccelMethod" "EXA" line to Section "Device" of xorg.conf:

Code:

Section "Device"

        Identifier  "Card0"

        Driver      "radeon"

        VendorName  "Unknown Vendor"

        BoardName  "Unknown Board"

        BusID      "PCI:1:0:0"

        Option      "AccelMethod" "EXA"

EndSection

X Window using EXA acceleration method works flawlessly. Here's comparison of Xorg.0.log without and within EXA:

So to avoid random system hang ups is enough to include in xorg.conf that option:

Code:

Option "AccelMethod" "EXA"

Hi,

I'm getting a error when I run the script 'get-xf86-video-ati';

Code:

rm -rf xf86-video-ati

git clone git://cgit.freedesktop.org/git/xorg/driver/xf86-video-ati

cd xf86-video-ati

git checkout -t -b master origin/master

cd ..

# package the source archive and clean up:

( cd xf86-video-ati ; find . -type d -name .git -exec rm -rf {} \; 2> /dev/null )

DATE=$(date +%Y%m%d)

mv xf86-video-ati xf86-video-ati-${DATE}_git

tar cjf xf86-video-ati-${DATE}_git.tar.bz2 xf86-video-ati-${DATE}_git

rm -rf xf86-video-ati-${DATE}_git

Code:

fatal: git checkout: branch master already exists

I'm getting the same error but xf86-video-ati-20091011_git.tar.bz2 source package is valid.

As I described in post #33 above I solved the problem using default xf86-video-ati 6.12.2 build 2. Driver xf86-video-ati 20091011_git includes option EXA by default. With driver xf86-video-ati 6.12.2 you have to include that option in xorg.conf yourself:

Code:

Section "Device"

        Identifier  "Card0"

        Driver      "radeon"

        VendorName  "Unknown Vendor"

        BoardName  "Unknown Board"

        BusID      "PCI:1:0:0"

        Option      "AccelMethod" "EXA"

EndSection

Try it and perhaps you'll avoid to install GIT version of the driver.

I encountered new problem with enabled:

Code:

Option "AccelMethod" "EXA"

When I run X Window as first user with startx command and then I run X Window as second user with startx -- :1 command the second user's session slows down when using such programs as: Firefox, Seamonkey, Konqueror, Opera etc. During window operations CPU usage for X jumps up to 97%. The first user can use these programs smoothly.

I found the solution of that problem as well. It's enough to enable:

Code:

Option "MigrationHeuristic" "greedy"

So my Section "Device" looks now:

Code:

Section "Device"

        Identifier  "Card0"

        Driver      "radeon"

        VendorName  "Unknown Vendor"

        BoardName  "Unknown Board"

        BusID      "PCI:1:0:0"

        Option      "AccelMethod" "EXA"

        Option      "MigrationHeuristic" "greedy"

EndSection
