That would be somewhat pointless, since the libgl1-mesa-dri package does
not contain the nouveau 3D driver. Besides, libgl1-mesa-dri is
installed by default (recommended by xserver-xorg), and users of the
proprietary drivers don't need it.

That does not help, the nouveau 3D driver is shipped in the
libgl1-mesa-dri-experimental package which does not exist^W^W^W is not
supported. Anyone who _really_ wants to use nouveau 3D should build a
snapshot from mesa git master instead¹ and be prepared for random GPU
lockups that require a reboot.
