--- Comment #18 from Martin Stolpe martinstolpe@gmail.com 2011-09-30 16:07:30 PDT --- Hello,
I've found the problem why it didn't work. I didn't know that the entry funtion (or whatever it is called) has to have the same name as the driver. After creating a xorg.conf file I was able to successfully start the Xorg server. It's working great on my two systems (no problems after rebooting the system). One system has a r500 type card installed and the other system has a r600 type card installed.
When I enable 2d acceleration in xorg.conf I get screen corruptions though (see attached screenshots of Firefox). There is an error/info message in the Xorg log file: "[ 2724.965] (II) r300(0): xorg_composite_accelerated fallback Component alpha not supported with source alpha and source value blending. (op=3)" This message is the same for both cards.
Best regards Martin
