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.

So, you mean if I can start X without gnome at all and then try running vlc with basic X server, right? Will try...

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?

Sure, but you have to tell me how. I can get backtrace for apps like vlc from the terminal but for which app shall I get this bt? gnome-shell? Even then I am pretty clueless how to do it...Sorry...But if you give me some tips I'll do my best..
