We debugged that a bit today, and found that X segfaults when it tries to open
a GPU channel.

Both DDX module and libdrm are now compiled from their git branches.
kernel log is quiet in regard to errors.

This looks like an ABI issue, most likely you're running a version of libdrm
different to the one your DDX module was compiled with.

Try "ldd /usr/lib/xorg/modules/drivers/nouveau_drv.so |grep libdrm" to
find out
which libraries are being used, and, in case they aren't what you'd
expect,
remove them, and make sure you're installing libdrm and the DDX to the right
prefix.

We did compile both libdrm and DDX. And installed both to /usr. I don't
think
its ABI issue (although I also suspected that first)

Although, knowing that ubuntu plays games with libdrm and installs it to /lib
or something crazy like that, it could be.

Also, before we compiled it, I more or less verified that stock ubbuntu
packages or X and libdrm were used.

It was indeed ABI problem. libdrm was pulled from /lib. Now it works
