I'm using kubuntu lucid development branch now.
I've got R600 card, so I installed (or, more precise, compiled) OSS drivers - libdrm-radeon with radeon experimental api, mesa with r600_dri and xf86-video-ati. The last one is installed because I couldn't compile it, but the one provided by .deb package is quite recent (6.12.99-20090929).
At first I tried KMS, and it worked quite well. But performance was rather bad, and causes some stutters, etc. So I placed radeon.modeset=0 into grub and I'm now using good-old UMS in DDX driver.
And here comes the question: here is a fragment of glxinfo:
It means that server provides GLX version 1.2. But many applications require some newer functions (like glXCreatePixmap from 1.3). I didn't have such problems with KMS (AFAIK, I didn't notice what GLX version did it provide but one application that used to work for sure now doesn't). Is it possible to get higher GLX version with DDX driver UMS? Or does it require KMS/DRI2?
Thanks.

server glx vendor string: SGI

Thanks.
