Xnview Kubuntu Wayland client buffer integration

[sacharja]

Hi,

got the following issue:
when using the deb file in a standard Kubungu 23.04 Wayland session, I just get the error "dependencies cannot be satisfied". After using the tar archive and executing ./xnview.sh , I get the following:

Does anyone have and idea what I'm missing here?

According to https://github.com/pyinstaller/pyinstaller/issues/6483 it's because "the Wayland Qt plugins are not included, so only Xorg is supported. If you do not force wayland to be ignored (unset WAYLAND_DISPLAY or set QT_QPA_PLATFORM=xcb) you get the error message".

Any chance to include the wayland QT plugins in the next version? Wayland can be tested in Kubuntu via settings > start & shutdown > behavior > automatically login with wayland

[xnview]

do you have checked this post

[sacharja]

Thanks, but all listed dependencies there are already installed. Installing the deb via console also works fine without error message:

sudo dpkg -i 1.deb
(Lese Datenbank ... 284934 Dateien und Verzeichnisse sind derzeit installiert.)
Vorbereitung zum Entpacken von 1.deb ...
Entpacken von xnview (1.4.5) über (1.4.5) ...
xnview (1.4.5) wird eingerichtet ...
Trigger für desktop-file-utils (0.26-1ubuntu5) werden verarbeitet ...
Trigger für mailcap (3.70+nmu1ubuntu1) werden verarbeitet ...

[sacharja]

BTW: in the same plain Kubuntu xnview is working well in an x session. But as soon as Kubuntu is being restarted in wayland xnview fails to start, so I guess this is indeed related to some missing wayland stuff (maybe it's working in plain Ubuntu because it's running there as xwayland).

EDIT: Setting this env leads to some progress when starting xnview from the console, but still no GUI visible and still the dependency error in qapt:

Code: Select all

export QT_QPA_PLATFORM="wayland;xcb" #workaround for xnview from https://wiki.archlinux.org/title/wayland

I have the same problem on gnome Debian 12 except that it runs in a Wayland session, but in X11 mode. Install through apt-get.

Here what happens when starting it normally:

Going by

qt.qpa.wayland: Attempted to load the following shells ("xdg-shell", "xdg-shell-v6", "wl-shell", "ivi-shell")

I think I found the requested shells though under /usr/lib/x86_64-linux-gnu/qt5/plugins/wayland-shell-integration/
file:///usr/lib/x86_64-linux-gnu/qt5/plugins/wayland-shell-integration/libivi-shell.so
file:///usr/lib/x86_64-linux-gnu/qt5/plugins/wayland-shell-integration/libwl-shell.so
file:///usr/lib/x86_64-linux-gnu/qt5/plugins/wayland-shell-integration/libxdg-shell.so
file:///usr/lib/x86_64-linux-gnu/qt5/plugins/wayland-shell-integration/libxdg-shell-v5.so
file:///usr/lib/x86_64-linux-gnu/qt5/plugins/wayland-shell-integration/libxdg-shell-v6.so

I am not too knowledgeable about linux, but doesn't that indicate that these shell-integrations actually exist but xnview for some reason doesn't find them?

The following packages and its dependencies concerning QT have been installed:
qtwayland5

I also tried adding these 2, no difference
qt5-gtk-platformtheme
qt6-gtk-platformtheme

The only other thought I have is that this is a fresh Debian installation that is very barebone without any software, not even system tools. For some reason it has a hard time to make apps run Wayland out of the box, I had to force many apps to run Wayland through setting and everionment variables, otherwise they prefer xWayland despite it being a Wayland session. Maybe something is missing which makes apps default to X11 despite it being a Wayland session.

In my opinion related observations to the Wayland issue and it running on X11:
1) XnView has no cursor in fullscreen. It functionally exists, but is not visible. That issue exists for all apps running on xWayland/X11 on my system. Once they run on Wayland the issue disappears.
2) Cropping images does not work, I can't draw with the rectangle mouse. I need to enter the coordinates of where to crop manually in the fields on top. The mouse seems to have no function in the image part of the window.
3) Watching videos fully crashes the computer, everything becomes unresponsive, the video never loads.

To me 1 and 2 at least are probably related to it running on X11 instead of Wayland. I assume 3 is related to it to, this Debian install doesn't take kindly to any app running X11 which tries to do anything visual or mouse related.

>I also tried adding these 2, no difference
Thanks, also thought about trying that one.

>Maybe something is missing which makes apps default to X11 despite it being a Wayland session.
you can put the following in your ~/.profile and it defaults to wayland and falls back to x11 if wayland is not working:

Code: Select all

export QT_QPA_PLATFORM="wayland;xcb"

Guess that xnview is never running as native wayland application, only as xWayland if it all possible.

[xnview]

ok, it will be fixed in next release...

[sacharja]

wow, that would be awesome (BTW: Kubuntu / KDE will default to wayland for the next release end of the year)

[sacharja]

Seems v1.5.0 deb is still not working with wayland. However, I found that the flatpak is currently working in Kubuntu Wayland

Then I tried to install it with apt:

Code: Select all

kubuntu@kubuntu:~/Desktop$ sudo apt install ./1.deb

Hinweis: »xnview« wird an Stelle von »./1.deb« gewählt.
Einige Pakete konnten nicht installiert werden. Das kann bedeuten, dass
Sie eine unmögliche Situation angefordert haben oder, wenn Sie die
Unstable-Distribution verwenden, dass einige erforderliche Pakete noch
nicht erstellt wurden oder Incoming noch nicht verlassen haben.
Die folgenden Informationen helfen Ihnen vielleicht, die Situation zu lösen:

Die folgenden Pakete haben unerfüllte Abhängigkeiten:
 xnview : Hängt ab von: libgdk-pixbuf2.0-0 (>= 2.22.0) ist aber nicht installierbar
E: Probleme können nicht korrigiert werden, Sie haben zurückgehaltene defekte Pakete.

Translated:

The following packages have unmet dependencies:
xnview : depends on: libgdk-pixbuf2.0-0 (>= 2.22.0) but is not installable
E: Problems could not be corrected, you have defective packages that were hold back

Within Kubuntu there's a library installed called libgdk-pixbuf-2.0-0 (with a minus before the 2).

EDIT: anyhow, I think the Flatpak version is currently the best for Unix, since this is the only one that automatically updates in Kubuntu (KDE Discover)/ Ubuntu (Ubuntu Software)(and might be the easiest to maintain in the long run).

Many thanks for making XnView Wayland capable.
