One thing I don't see you mention, is switching between the classic and
gallium OpenGL implementations. Again, I've not played with gallium much,
and it may be that this doesn't apply to intel at all, but at least for
radeons, eselect mesa is used to list and switch between the classic and
gallium drivers. You mention trying with gallium, but not specifically
switching to the classic drivers and trying that. Perhaps that's why you
got the segfault with mesa emerged -gallium, as if you hadn't eselect mesa
switched to the classic drivers, it could have tried to load libraries
that didn't exist in that case, thus triggering a segfault.
I think that was definitely a portion of the puzzle. I had never
selected gallium before, so it never wasn't using the classic driver.
Which makes the segfault even more mysterious. I selected gallium for
all the options and I now have a hang again (it went away when using
- -gallium, forgot to mention that). My updated glxinfo is attached. I
think it's odd that glxgears works but not pyglet. It may be like you
mentioned, not accepting the software fallback. Oh, and selecting
gallium didn't move OpenGL onto hardware, it's still running in software.
Could it possibly be a kernel option somewhere? KMS is on and I compiled
in Intel DRM support. Just flailing around wildly for causes.
You might want to prepare for the possibility that your card just
doesn't work with KMS, even different cards from the same brand.
At home, I have a Radeon FireGL V3400 that just refuses to work with any
kind of KMS, and I finally gave up. You can disable it either by
building a kernel that defaults to not having it on, or by passing a
kernel parameter from Grub ("nomodeset").
At work, I have a Radeon HD4350 which works great with KMS on console
VTY's and in X11, and hardware 3D works fine also. Both machines are
running Gentoo with the 1.9 Radeon drivers and the 2.6.38.2 kernel.
KMS is just going to have to be something that works when it works for
now.
