    intel: Stop exposing useless 24 depth/0 stencil configs

Intel driver stopped exposing 32 bit visual.
That breaks compiz:

Comment 1 maximlevitsky 2010-07-07 05:07:08 UTC

Note that this only happens if xserver is compiled with --disable-aiglx

Comment 2 Jesse Barnes 2010-07-08 10:09:06 UTC

Reassigning to Ian, might be fixed already.

Comment 3 maximlevitsky 2011-05-23 09:50:49 UTC

Nope, the bug isn't fixed, just tested.
However, for more that a year, I haven't found a case to use --disable-aiglx, as now xservers do play nice with various versions of mesa DRI drivers.
So I close this to get it from my buglist
