Bug#379940: boson: detects incorrectly DRI off, when DRI on

[Andreas Beckermann]

Hi
first of all: DRI drivers usually don't work very well. They have lots of 
problems and produce a lot of "weird" effects. That said direct rendering 
_should_ work with DRI drivers.

Finding the issue however is a pretty difficult issue. Let's try some shots 
into the dark, please post:
* The output of ldd /usr/games/boson
* The output of ldd /usr/bin/glxgears
* The output of glxinfo
* The first about 20 lines of console output when starting boson

btw:

actually it's the other way around: the bug report is poorly worded. This is 
not a message about DRI (Direct Rendering Interface), but about "direct 
rendering" (hardware accelleration). E.g. proprietary NVidia drivers support 
direct rendering just fine, but don't support DRI.
Boson checks the result of glXIsDirect(), which tells whether the GLX context 
is direct (accellerated) or not. So the warning message is just fine :-)
