I have a quite weird DRI problem:
On startup, when I login for the first time via kdm, 'LIBGL_DEBUG=verbose glxinfo' says
libGL error: drmMap of framebuffer failed (Invalid argument)
Then, after I logged off, kdm restarted and I logged in again, everything seems fine. The 2D direct rendering in kde works alright, but apps like glxgears show only a black screen. In zsnes I can see and move the mouse pointer on a black background.
I'm currently using:
which I emerged in this order.
I hope someone can help me,
PS: I emerged x11-base/x11-drm-20071019 too, but I actually don't know whether I'm using x11-drm or the built in kernel drm (how can I find out?).

Forget that. I unmerged x11-drm and still got the same problem.
fixed it all by removing the virtual resolution of 2048x2048 in the screen section of my xorg.conf.
sorry for bothering you ;)
