--- Comment #16 from Michel Dänzer michel@daenzer.net --- (In reply to mehmet.giritli from comment #15)

Christian, I've been trying in whatever free time I have to run mesa git on my laptop but my gnome shell does not seem to be working with it.

Note that you technically don't need to run anything but vlc with Mesa Git. You can point libvdpau to the Mesa Git build of libvdpau_r600.so via the environment variable VDPAU_DRIVER_PATH.

Jun 13 13:43:54 frodo gnome-session[814]: gnome-shell: /tmp/portage/media-libs/mesa-9999/work/mesa-9999/src/gallium/drivers/r600/ r600_pipe.h:902: r600_conv_prim_to_gs_out: Assertion `mode < (sizeof(prim_conv)/sizeof((prim_conv)[0]))' failed.

Can you get a backtrace for this with gdb?
