enable gnome-shell to run with software rendering (llvmpipe)

Bug Description

fedora 17/18 have gnome-shell running with software rendering (llvmpipe). On Ubuntu gnome-shell will only run when hardware 3D is available.

This would be particularly useful for the ubuntu gnome live CD's

llvmpipe is currently blacklisted in gnome-session hardware-compatibility.

Removing the blacklisting, is enough to get both gdm and gnome-shell running with llvmpipe (no fallback mode!). I have tested this in a VM and performance seems ok, definitely useable. It is atleast as fast as the equivalent Unity session, if not a little faster.

This is about all I could find on the fedora implementation. At the very least need to remove llvmpipe from blacklist in gnome-session.


There is talk on that page of virtual GEM kernel drivers and modifications to Mesa/X, however its not really clear if any of that has been done.

I have tested gnome-shell running with llvmpipe (in a vmware VM) and it seems to work quite well.
