I’m currently running openSUSE 12.3 on a laptop with a radeon HD 3xxx series GPU and require 3D support. I know this isn’t possible with the open source driver and AMD appear to have no plans to change their support for legacy flgrx running under xorg 1.13 any time soon. The obvious is go back to openSUSE 12.2 and xorg 1.12 but that would be a shame as 12.3 is so much better.
Is it possible to downgrade xorg to 1.12?
If so are there any pitfalls that need to be avoided?

Hi
AFAIK, not possible…
Have you tried enabling glamor?
/sbin/lspci -nn|grep VGA
01:05.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI RS880M [Mobility Radeon HD 4200 Series] [1002:9712]
glxinfo |grep 3D
GL_EXT_texture3D, GL_IBM_rasterpos_clip, GL_ARB_point_parameters,
glxinfo |grep direct
direct rendering: Yes
cat /etc/X11/xorg.conf.d/20-radeon.conf
Section "Device"
Identifier "radeon"
Driver "radeon"
Option "AccelMethod" "glamor"
EndSection

No I haven’t heard of ‘glamor’ but a little googling gave me a better understanding. Before attempting this, is it just a simple case of using your code? As I have read some kernel configuration or possible recompile is necessary before running ATI driver with glamor enabled. Although not a complete novice I haven’t much experience at compiling, early attempts ended in dependency hell so have tried to avoid if possible.

Hi
Yes, it’s already enabled in openSUSE. Just add the 20-radeon.conf file
as indicated. Reboot, then look in the Xorg and you should see something
like;
cat /var/log/Xorg.0.log|grep glamor
(II) LoadModule: "glamoregl"
(II) Loading /usr/lib64/xorg/modules/libglamoregl.so
(II) Module glamoregl: vendor="X.Org Foundation"
(**) RADEON(0): Option "AccelMethod" "glamor"
(II) Loading sub module "glamoregl"
(II) LoadModule: "glamoregl"
(II) Loading /usr/lib64/xorg/modules/libglamoregl.so
(II) Module glamoregl: vendor="X.Org Foundation"
(II) glamor: OpenGL accelerated X.org driver based.

(II) RADEON(0): glamor detected, initialising EGL layer.

Enabling glamor as worked for me. I don’t have the same performance as the fgrlx drivers but this is to be expected and for my needs is more than good enough. Seems to be running stable (time will tell) and the only issue I have encountered to date is using the new KInfoCentre app. When querying OpenGL info it results in the KDE session restarting and since I don’t use this app its not a problem.
Many thanks for solving this and keeping me on openSuse12.3
