As said - glxinfo will list all the possible configurations. Anyway, a
combination of alpha bitplanes and 8 subsamples is not supported on IR right
now. The possible configurations in terms of color bitplanes and multisampling
are :

either 12 12 12 12 bits for RGBA and 4 samples
or 10 10 10 bits for RGB and 8 samples.
