Now is a difficult period when both gtk4 and old gtk3 plugins are
relevant. Let's add a list for gtk4. Needed for gnome 45.
New target will be used for gtk4 gui. For now this is
gnome-control-center in Sisyphus and in the future p11 branch.

Oh those tags. Let's just make lists so we don't have to rack our brains.
Lists are perceived much easier.

It is correct to run them with native systemd units, and not through
prefdm.

It is not needed, since priority is given to kde5-display-manager-lightdm.
Besides, it never worked.

No plans to build image with kde5 and sddm.

This is necessary to remove the /lib/systemd/system/display-manager.service
from xinitrc in the future.

See: https://bugzilla.altlinux.org/48305

Causes:
1. overriding synaptic-usermode does not work when using the main
repo and installing from packages. use/live-install is affected
by this bug: https://bugzilla.altlinux.org/47862
2. synaptic is not part of kde5. And in the regular-kde5 can use
synaptic-usermode package.

Removed from Sisyphus.

This list has nothing to do with lxqt.

too big for live.

There are no proprietar videodrivers for Radeon in the repository.
The variable is needed to switch between proprietary and its free
video drivers. No longer needed.

use/x11/xorg is also used to build VM images that are intended for
virtual machines and SBC. For VM targets do not need support for
discrete video cards, as a rule.

Enlightenment uses acpid for power management.

xscreensaver has more than its main package and the details
of what to get where might be confusing for some of us;
in particular, there are 2D and 3D hacks collections
(and some arches would rather prefer to avoid 3D for now),
desktop file sets aimed for MATE/Xfce, and the frontend.

So let's provide some basic reusable targets.

Looks like a plain omission.

Rollback from use/x11/nvidia/optimus to plain use/x11/nvidia
for now as I don't have a proper x86 stand to test it now;
feel free to revert this part if you do and bumblebee works.

xmonad not available for p10 and newer branchs.

sugar not available for p9 and newer branchs.

This target can be used for more than just regulars builds.

primus removed from Sisyphus.

Protection against apt-get autoremove.

NB: deepin-polkit-aget not worked, so replaced to polkit-gnome.

Raising the priority of a targeted package does not help, and
lowering the priority of a non-targeted package helped.

With kde5-maxi image is too large (over 2 GB).

This is base target, drm not needed.

Suggested by lvol@

The drm feature solves the problem of creating a common entry
point for adding kernel drm modules for different package lists.
The need for allocation into a separate feature arose from one
parties to the need to make a switch between free and proprietary
NVIDIA driver, on the other, because of the need to add only drm
modules kernels for purposes such as use/stage2/kms and use/plymouth.

Also no more switch needed for RADEON, as only the free video driver
remains.

Tested to work in practice.
