Supply custom .desktop file for .deb builds to fix icons under GNOME

[nabijaczleweli]

StartupWMClass was "Haveno", which didn't work under GNOME (see screenshots under #1906). Specifying it to be the full class name correctly associates the windows to the icons.

This also merges some non-functional/display-only wording from the hand-written desktop files: Name/GenericName/Comment are fixed from "Haveno"/(not present)/"Haveno".

Closes #1906

Hm, I installed it with:

sudo dpkg -i ~/Downloads/haveno-v1.2.0-linux-aarch64-installer.deb 

And run it with:

/opt/haveno/bin/Haveno

But for some reason still missing the icon:

Hopefully you are able to see the same. I'm running Ubuntu 24.02.

I can't reproduce this on GNOME (dpkg -i, no additional postprocessing, but launching from the launcher since launching directly fails mentioning $DESKTOP). I'll try installing Ubuntu.

Default settings fresh Ubuntu 25: app search, launched from app search, launched from xterm:

This is the type of thing that feels like it would be affected by running xorg vs xwayland? So I logged into "Ubuntu with Xorg" and it also works there:

I'm using the deb from https://github.com/haveno-dex/haveno/actions/runs/16974013546?pr=1917 for testing (and unpacking shows that both arches have StartupWMClass=haveno.desktop.app.HavenoApp), are you sure you got the right debs?

It's working :). There was some problem with my Ubuntu VM, but it works fine on a fresh install.

Please reply or DM an address for payout. Thanks for your help.

I really shudder to think what the problem could actually be in that case 🥴

Guessing it was just some caching issue with the icon. I found that Ubuntu caches icons aggressively, and needed to clear some caches on my fresh VM install in order to update the icon there too.

Payout made. Thanks again.
