To answer my own question, it seems that is possible. I wonder if it works with mutter/cogl???
It does.
However, your problem seems rather that gnome-shell/mutter doesn't support R200 anymore.
Yes, that's true. I wonder if I can revert the incompatible change or better create a env variable to revert to the compatible behaviour or something? I'll need to take a look...
I'm not sure how valid this is any more: https://bugs.freedesktop.org/show_bug.cgi?id=51658
Basic issue is that r1xx/r2xx hw only has a limited number of render buffer formats while they support a lot of texture formats. Gnome shell expects to be able to render to the same formats they can texture from.
It looks like a bit of a hack, it's a pity to lose valid texture formats, but I've applied the patches from the bug after a little manual intervention. It's building now, will take some time!
Didn't work. Still get the same error! :-(
On the other hand, I've got muffin to work compositor is actually okay, so thought I'd try cinnamon, but it's trying to use 1.5GB which isn't going to work! ;-)
Will probably revert to Xfce...
