May improve stability for X11 applications. Chase ports r525681.

Disclaimer: I've never used KDE on FreeBSD, let alone with Wayland.

Thanks, we are in the process of trying to get plasma-wayland to work/test/use it -- so that may be integrated into that work.

Can you test plasma-wayland with an NVIDIA GPU? Apply the patch in bug 244087, enable NVIDIA option in x11-servers/xwayland-devel then check if hardware acceleration works in X11 applications.
Comment 4 Jan Beich freebsd_committer 2020-12-16 12:20:06 UTC
Ping. Without this helping kde@ (e.g., bug 251836) is PITA for those who dogfood Wayland.

Are there any negative side effects when switching to the -devel port?

Comment 6 Jan Beich freebsd_committer 2020-12-17 17:18:11 UTC
None after years of dogfooding. Sway package switched when released version of Xwayland (1.19.1) was actually less stable than snapshot. Later I've applied a WIP patch written by a KDE developer and extended by others (see PATCHFILES) but it is nop for unaware consumers like cage/hikari/wayfire.

non-devel version currently lacks https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/515 which is critical for hardware acceleration.
Comment 7 Jan Beich freebsd_committer 2020-12-17 17:34:14 UTC
xwayland-devel is updated frequently (usually once a week), so poudriere will rebuild plasma5-kwin, plasma5-plasma-workspace, etc. which maybe a bit annoying. If you only rebuild plasma5-kwin then poudriere won't obsolete indirect consumers. I often use the trick with qt5-webengine to quickly test yuzu-qt5 (one of my ports).

poudriere supports -S flag to reduce rebuilds but it's partially broken atm. See also https://github.com/DankBSD/ports/commit/e0bf02a902b2

I would suggest using an option, what do you think?

Non-default options have no impact on binary packages e.g.,

  $ pkg install sway kde5

    - xwayland-1.20.9_2,1 conflicts with xwayland-devel- on /usr/local/bin/Xwayland
  Cannot solve problem using SAT solver, trying another plan

Comment 10 Max Brazhnikov freebsd_committer 2020-12-18 21:46:11 UTC
Is there a reason to keep both xwayland and xwayland-devel in the ports at all?
Comment 11 Jan Beich freebsd_committer 2020-12-18 22:36:53 UTC
Probably no, see bug 251947. From wlroots package POV I need xwayland fresh enough to support new features e.g.,
Comment 12 Tobias Kortkamp freebsd_committer 2021-03-15 22:09:48 UTC
Please do this because the status quo causes some silly and unnecessary
problems.  For example, I cannot install x11-wm/sway alongside

Number of packages to be removed: 5

For now I have resolved this by monkeying around with pkg set but
I really should not have to do this.

New revision: 568609
URL: https://svnweb.freebsd.org/changeset/ports/568609

  Switch KDE Plasma kwin (the WM & Compositor) to xwayland-devel

  This makes Plasma co-installable with sway and river and other
  Wayland-based compositors and makes life much easier for the
  folks working on Wayland bits, since then all the "current"
  compositors depend on the same wayland, rather than conflicting
  over xwayland vs. xwayland-devel.

Comment 14 Adriaan de Groot freebsd_committer 2021-03-16 20:44:27 UTC
For what it's worth, I spent a day last week wrestling with exactly this and locally patched the kwin port to build against xwayland-devel. I think it's a fine stopgap measure for getting all the "current" Wayland compositors and things building and installed at once, for comparison purposes. Once things settle down, we can step the non-experimental ports back from -devel and stick to release versions again.

I did write up my experiences at https://euroquis.nl/freebsd/2021/03/16/wayland.html , which come down to: well, kwin doesn't work with Wayland on FreeBSD anyway.
