Full screen can be set on the command line specifically '-FullScreen -FullscreenSystemKeys. For more details consult the manual xtigervncviewer(1).

To set command line options on programs started from your window manager consult your window manager's documentation. (It may be as simple as right click and select properties but as I do not know which window manager you are using I cannot give exact advice.

I edited /usr/share/applications/xtigervncviewer.desktop
and added:
Exec=/usr/bin/xtigervncviewer -FullScreen -FullscreenSystemKeys
Does not work for me. Also starts in windowed mode

Try starting it from a terminal, this will both allow you to see messages and minimize window manager issues for the moment. Also note that some window managers may interfere with or not support full screen applications.

Another option if you are setting up a kiosk is to use a full-screen window manager like ratpoison. note that ratpoison does not like full screen applications and behaves oddly when apps ask for full-screen but as it is already full-screen and does not use typical system keys it just works without the options set.

Dunno how to setup kiosk. I launched /usr/bin/xtigervncviewer -FullScreen -FullscreenSystemKeys IP:port directly from command line and the result is the same (window)

BTW the viewer works properly on Debian 11 and 12

[hildred]

If you were trying to set up a kiosk you would know what one was there fore you are not and we can ignore that. So the only question is there something with Ubuntu's package or the window manager. Can you try the official tigervnc build?

I have seen the same issue on Fedora 39. I think it is a problem with GNOME, it started happening quite recently. I cannot reproduce the issue when running XFCE locally.

Yes, at least on Gnome, the parameter -FullScreen is dead.
