Thanks for your answers! I have indeed fglrx installed for the Ubuntu kernel (bootable from a second grub entry). Is libGL made up by the <chip>_dri.so files or is libGL another file collection? My r300_dri.so is from a package by Andrius Štikonas which contains a backport of mesa with fixes by David Airlie for the Radeon XPress 1100 to work with DRI <A HREF="http://ppa.launchpad.net/stikonas/ubuntu">http://ppa.launchpad.net/stikonas/ubuntu</A> and <A HREF="http://airlied.livejournal.com/59351.html">http://airlied.livejournal.com/59351.html</A> . That package I installed after fglrx. Would uninstalling fglrx solve the problem or would I have to get another mesa (which includes libGL if I understood you right)?

Even if you're not using it, fglrx provides its own libGL.so which is incompatible with Mesa's, so you have to remove it before you can use the open source driver.
