I used the compiz wrapper in the past. It only gave me a blank screen
and I couldn't do anything else, unfortunately. :-( I was keen on seeing
what compiz.real showed as error messages and that is why I used it for
this bug report.
Now, the compiz wrapper just suggests me to use indirect rendering, when
invoked with --help. I guess that this is a non-bug, then.

Hummm, I see. :-(

Care to educate me here about what is lacking on the hardware-side of
things?

I would like to avoid the use of indirect-rendering to save some CPU
time.
Thanks, Rogério Brito.
