Arch Linux User Repository

This package currently has two problems:

First: Running this package on KDE Plasma on pure Wayland will not show the correct application icon (the one in the title bar).

Second: Besides the app icon, the package does not work correctly when using pure Wayland anyway, the preview of the PDF to place the signature is not shown.

The first problem is because the *.desktop file name is wrong. Currently it is pdf-over.desktop but it should be PDF-Over.desktop. Why? Because wayland is looking for information about the application in it's corresponding desktop file. And to look up the desktop file it uses the applications app-id. You can find that app id by running (under wayland!)

$ WAYLAND_DEBUG=1 GDK_BACKEND=wayland /usr/lib/jvm/java-21-openjdk/bin/java -cp '/usr/share/java/pdf-over/*' at.asit.pdfover.gui.Main "$@"
...
[ 583800.618] {Default Queue}  -> xdg_toplevel#37.set_app_id("PDF-Over")
...

So that's why the correct name of the desktop file here is PDF-Over.desktop. Actually if you install PDF-Over from their download page the name of the desktop file is correct, it will be placec under ~/.local/share/applications/PDF-Over.desktop.

For the second problem, we need to run the app with GDK_BACKEND=x11,wayland to force it to use Xwayland when running in a pure Wayland environment. Actually if you install PDF-Over from their download page, their start script does exactly that. See https://github.com/a-sit/PDF-Over/blob/pdf-over-4.4.7/pdf-over-gui/src/main/resources/scripts/pdf-over_linux.sh#L3

Here are the corresponding commits:

https://github.com/a-sit/PDF-Over/commit/4f6465b50e61ddbd36a1a113078fbe1247192b46

To make things easy for you I pushed the fixes to a pdf-over-fixes branch here: https://github.com/mkurz/aur/commits/pdf-over-fixes/

That branch contains two commits on top of the current master branch:

https://github.com/mkurz/aur/commit/bff50da02b2cac67228db5608f1f50fd8c8a7c5c

https://github.com/mkurz/aur/commit/be4a58cfcddf9e06b087e945a28e587375f213f7

You can apply them easily with:

git remote add mkurz git@github.com:mkurz/aur.git
git fetch mkurz pdf-over-fixes
git merge pdf-over-fixes

Afterwards to release a new version please do not forget to bump pkgrel to 2.

Thanks
