driver (in services.xserver.videoDriver), the X server is now given
a set of drivers, and will use PCI ids to find the right one.
The only problem is that the choice of OpenGL driver (the
/var/run/opengl-driver symlink) depends on what driver is selected
at runtime (i.e. the NVIDIA implementation for "nvidia", and Mesa
for all other drivers). However this isn't a big problem right now
since "nvidia" isn't included in the default set of drivers anyway
for legal reasons.
* `services.xserver.resolutions' now defaults to [], meaning that the
X server should figure out the desired resolution(s) itself.
Likewise, `services.xserver.defaultDepth' defaults to 0 to let the X
server figure it out.
* Removed some options from xorg.conf that no longer appear needed
("Composite" and the DRI "Mode").
