Comment # 6 on bug 991334 from Stefan Dirsch

This really looks like you don't have the install medium/repo any longer
accessible in/from your system (possibly you removed the DVD or alike).
Otherwise zypper would simply install the Mesa packages, which provide the
necessary components. This needs to be fixed first.

In addition I suggest not to have the nvidia driver manually installed in
parallel to our packages, since this usually results in a messed up system.
Manually installed nvidia driver can be uninstalled via

  nvidia-installer --uninstall
