Bug#928297: xserver-xorg-core: miss dependency in libgl1-mesa-glx -> effectively depends on libgl1-mesa-dri
Package: xserver-xorg-core
Version: 2:1.19.3-2
Severity: important
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512
xserver-xorg-core 2:1.19.3-2 has Depends: libgl1-mesa-glx | libgl
xserver-xorg-core 2:1.19.4-1 has Depends: libgl
That change makes it impossible to install Xorg without DRI modules.

Package 'libgl1' is not installed, so not removed
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
xserver-xorg-core : Depends: libgl1 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I see no mention of need for tightening dependencies in changelog entry
for 2:1.19.4-1, and suspect that this change may be purely accidental.
