As a warning, the any X snapshot that hits a mirror around the time of
this email (they're currently copying out) will contain an update to the
radeon driver to 6.9.0. The r128 and mach64 drivers have been split out
in this release, but the "ati" wrapper should take care of that.
Now, there's some changes in this driver update that you may wish to be
aware of:
macpcc users:
if you use any quirks for your macbook, or have a mac, you may
want to check "man 4 radeon" and look at the "MacModel" option
if you have any trouble. The old mac quirk option (the name of
which escapes me right now), has been removed.
dual head users:
If you used "MergedFb", i warn you that this has also gone,
superceded by xrandr 1.2. so if you use this in your setup, i
recommend you look into migrating. while intel specific, the
following page has some generally useful information:
http://www.intellinuxgraphics.org/dualhead.html
EXA acceleration:
this driver makes the EXA acceleration method the default (the
snaps also have a change to make intel default since bugs in it
have been fixed with the xserver update). Sometimes this
acceleration method is still a little slow (or quite slow in
some cases), so if you find the driver to be acting slower than
you're used to, first try:
Option "MigrationHeuristic" "greedy"
in xorg.conf. We may make this default until we update to
xserver 1.5, which needs to wait for it to be finalised and
released.
If it's still too slow, then instead you can revert to XAA
acceleration for 2d using:
Option "AccelMethod" "XAA"
A note on newer cards:
This new version of the radeon driver also supports newer cards
normally treated by the radeonhd driver, if you normally use
that driver, feel free to try this one if you're having any
trouble.
That should be all the gotchas. If you notice any regressions, please
notify myself (oga@) and Matthieu Herrb (matthieu@)
Cheers,
