"$ Xephyr :2
$ DISPLAY=:2 glxinfo
Error: couldn't find RGB GLX visual or fbconfig"
The issue happens on Ubuntu quantal or raring with xserver-xephyr 1.13, installing the precise binary (1.12) makes it work
jcristau suggested on IRC that kdrive might need something similar to http://cgit.freedesktop.org/xorg/xserver/commit/?id=ac1a60e7b6f06fd075cc5bf55d6bc67206a01d29

That patch fixes the issue for me (on 1.13.2)
similar to the commit previously pointed, it does the job it seems ;-)
Could you provide that patch in git-format-patch form with an appropriate signed-off-by line?

updated patch, in git format, for the current trunk
> Could you provide that patch in git-format-patch form with an appropriate signed-off-by line?
sure, I guess the signed-off should have your name?
There you go!
It would hopefully have your name, assuming you're the author of the patch, indicating that you agree with the developer's certificate of origin (https://www.kernel.org/doc/Documentation/SubmittingPatches)

updated patch with the right signed-off
oh, ok, thanks!
Thanks! It's on the list with a fixed up commit message, though it ended up at the *end* of a giant patch series I sent out. If that all gets stalled I'll try to make sure it makes it in anyway.
