Hello all,

I'm just trying out whether FreeBSD could replace my Linux installation 
on my notebook, so not entirely sure whether this is the right place to 
ask -- if not, sorry for that and please give directions to the right 
place, thank you.

Most things work just fine, but DRI does not work:

[    49.676] (II) AIGLX: Screen 0 is not DRI2 capable
[    49.676] (II) AIGLX: Screen 0 is not DRI capable
[    51.511] (II) AIGLX: Loaded and initialized swrast
[    51.511] (II) GLX: Initialized DRISWRAST GL provider for screen 0

So I checked the kernel output and found the following:

As https://wiki.freebsd.org/Graphics lists my chip with "Works", what 
could I have missed here? Could it be anything in 11-current breaking 
this, so trying 10.1 could help?

Thanks for help/ideas/hints ...

Best regards,
Felix
