This is port of the:

It is first part of the Wayland migration patches to Fedora.

Resolves: https://fedoraproject.org/wiki/Changes/Anaconda_As_Native_Wayland_Application

TODO:

Ready for review

  • Tested on boot.iso - works as expected
  • Tested on KDE Live - works almost as expected (there is minor bug when switching keyboard layout in system)
  • Tested on Sway Live - works with additional fixes (new sway-config package needs release + Remove variant before setting new localed layouts alebastr/sway-systemd#30)
  • Tested on Fedora Workstation - works as expected (not impacted by this change from my testing)

Can we please put the VNC stuff back? GRD supports VNC and RDP, and there are many more high quality VNC clients than there are RDP clients for Linux. And even the first party Mac remote desktop client is VNC-based, not RDP.

@Conan-Kudo as said a few times. I won't do that from start. This is already quite heavy patch set and getting into this VNC would make it just heavier.

Also based on the GRD maintainer reply it doesn't sound wise move in the current situation https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/G4DFKOUDDDDYHNQBNYRH52XVYKWK5X2U/

Added support for localed. Unfortunately we can't merge this until this is resolved https://pagure.io/releng/issue/12275 because it's blocking one of our new dependency.

Also I need to do testing on Live to find how it behaves there.

Because of the switch to Wayland Anaconda has to change compositor
keyboard manager because libxklavier doesn't work on Wayland.

To fix that we migrated to Gnome Kiosk DBus API in RHEL-10, however,
this solution can't be used outside of Gnome Kiosk. For that reason,
we are switching to Localed which we set as the default to enable
Anaconda to control keyboard switching.
This code is not used since migration to Wayland. We need another
solution for this feature.
The GRDServer class have checks in the __init__ method which starts to
complain about missing GRD in the system. That doesn't apply in Live
environment where we don't support GRD in the first place.
This logic was used to disable keyboard switching for given system.
However, we we support even Wayland systems with the new solution, so
let's remove this.
Previously it was vnc but we switched to RDP instead.
If Anaconda will set keyboard layouts to compositor but options are
missed then we shouldn't change the compositor options but rather use
what is already set.

This will avoid problematic behavior of changing what user has defined
in the system or similar cases. Also we have this tested in
kickstart-tests, so this commit is fixing these tests.

Also fix existing tests and cover this functionality by tests.
We need to disable these repositories to avoid dependencies from it.

With this changeset we depends on gnome-remote-desktop which depends on
librdp which depends (Fedora only) on openh264. However, if fedora-cisco
repository is not enabled it will instead install noopenh264 package
which is a stub package in the main repositories.
Move the GRDServer class creation to the end of the `setup_display`
method. This class have checks for binaries in the `__init__` method
which is causing early failures. Also do not create the class if it is
not really used.
The Wayland/RDP support broke the installer running on s390x z/VM and LPAR.

Resolves: RHEL-45516

There is a new patchset to migrate Anaconda to Wayland native
application. This patchset is unfortunately quite big and complicated.
rhinstaller/anaconda#5829

Current Web UI testing depends on updates image creation from the
Anaconda RPMs which are downloaded from Rawhide and/or COPR repos.
However, we are hitting issues for updates images in this case.

- Removal of spoke in Anaconda will not be covered by updates image.
  This is expected because RPM don't have information that some file
  was removed. Usually this is not an issue because the removed code is
  not imported. Unfortunately, here the code is imported by our
  dynamic spoke importer. That will result in traceback because
  of missing imports in the removed spoke.
- The patchset in Anaconda is adding new dependencies required to be
  able to start the Wayland environment, however, these are not covered
  when an updates image is created because we can't tell which deps are
  new and should be part of the ISO.

We should resolve this somehow by improving the workflow in the future.
For now we can continue with this hotfix.

We have agreed that although the Web UI tests are broken on this PR - we need to merge it - and wait for the new ISO to include the new deps for wayland for the Web UI CI to consume.

All the efforts we did to make this work ended unsuccesfully (Manual testing of Web UI happened - it looks fine).

For the reference, these kickstart-test flakes / issues started to appear also on daily-iso after merge of the PR (used to be seen only on rhel-10 before):
