I note that Synaptic, in doing a search on xserver, shows, among the
list of various packages apparently installed (as I can not copy the
list, as a block copy, a command line command to so list the packages,
would be useful, eg "apt-get list-intalled | grep xserver"), are the
following two packages;
"
X.Org X server -- NV display driver
This driver for the X.Org X server (see xserver-xorg for a further description)
provides support for NVIDIA Riva, TNT, GeForce, and Quadro cards.
Note that this is not the same as the binary-only 'nvidia' driver, which
adds 3D support, but is binary-only and not supported.
More information about X.Org can be found at:
<URL:http://www.X.org>
This package is built from the X.org xf86-video-nv driver module.
"
and
"
X.Org X server -- Nouveau display driver (experimental)
This driver for the X.Org X server (see xserver-xorg for a further description)
provides support for NVIDIA Riva, TNT, GeForce, and Quadro cards.
Although the nouveau project aims to provide full 3D support it is not yet
complete, and these packages do not include any 3D support.
Users requiring 3D support should use the non-free "nvidia" driver.
This package is built from the FreeDesktop.org xf86-video-nouveau driver.
"
>From the information that I posted in my last previous message, I
assume that these packages, like other xserver packages that are
apparently installed but irrelevant, are not being used?
