The kubernetes module does no longer add the kubernetes package to

The <literal>intel</literal> driver has been removed from the default list of
<link linkend="opt-services.xserver.videoDrivers">X.org video drivers</link>.
The <literal>modesetting</literal> driver should take over automatically,
it is better maintained upstream and has less problems with advanced X11 features.
Some performance regressions on some GPU models might happen.
Some OpenCL and VA-API applications might also break
(Beignet seems to provide OpenCL support with
<literal>modesetting</literal> driver, too).
Users who need this functionality more than multi-output XRandR are advised
to add `intel` to `videoDrivers` and report an issue (or provide additional
details in an existing one)
