I was using my xedgers latest and now I have latest of 04-03-2010. How do I downgrade to your package? I added your ppa to my source list. However, Xedgers is superseding your package. I deselected xedgers from the source list and did a refresh however I still have xedger versions.
Thanks for your help.
I use Synaptics where you can choose "force-version".
Otherwise I'm currently building a new version which will superseed their build. Here is a tip to lock version so it does not automatically upgrade to any other.
If you lock the version you need to manually check if there is a newer build from me,
xorg-edgers to the rescue http://launchpad.net/~xorg-edgers/archive/radeon
Currently, these mesa packages install on plain lucid (and not on top of the main xorg-edgers PPA), but since this might change later, please check the PPA page description before upgrading from it or asking questions.
Note that the xserver picks up the driver in /usr/lib/dri for AIGLX when it starts up, so to feed it with classic you will have to rename the directories (better rename back before upgrading/uninstalling packages again). I am not sure which part of the driver the AIGLX is using and for what so I can not tell what difference that makes (explanations are welcome).
The plan is to provide the gallium drivers also for intel and nouveau, but they can not build on plain lucid, so that will be for the main xorg-edgers PPA (with updated libdrm etc). There the default will likely be the classic drivers in the first place, with a dri-gallium directory for testing.
I see bugs are getting filed and commented on at https://bugs.freedesktop.org/ (Product = Mesa, Component = Drivers/DRI/Radeon) with "r300g" in the bug titles. The intel gallium driver uses a separate component Drivers/Gallium/i915g though. For r300 and r300g it is mostly the same developers anyway.
r300g is showing a nice improvement in 3D performance.
The 2.6.34 are the Ubuntu mainline builds and 2.6.31 is the Lucid kernel.
There seems to be a bug in the Lucid 2.6.31 kernel because I'm seeing a huge performance drop after a short time. I've rebooted on each benchmark with no other apps running. Every time the Lucid kernel drops in performance after 1 or 2 runs of the OpenArena benchmark.
