Wayland: 'GDK_IS_X11_DISPLAY (display)' failed

[fredfortier]

I'm using Fedora 29 with Gnome and Wayland and a fractional screen resolution. I built the project from sources. I can run headless modules but get this error when starting the bisq-desktop. This seems to indicate that the app expects an X11 server but I'm not sure. If so, is there a way to build for Wayland.

getting this exact same error.

yes, I have stumbled over the issue as well. see bisq-network/roles#78 (comment) for reference.

not sure what we can do about that. sounds to me as if the jdk is at fault.

On manjaro gnome (Arch linux + gnome-wayland), I get the same error with the AUR package bisq (0.9.3-1) and the app crashes.
But with the AUR package bisq-bin (0.9.3-2), by executing the app from the terminal by typing bisq, I see that some errors are still there, but the app displays on the screen and is usable.

I found a proposed fix which has been rejected.

However, adding a -Djdk.gtk.version=2 to the VM arguments does the trick for me!

Closing as complete based on #2279 (comment).

I have the same crash issue running on Debian with GNOME 3 (Wayland). See bisq-network/support#896. Please could you re-open this issue (perhaps the resolution involves javafx upgrade as per #3630)

@pandascrape can you please retry with the latest version (v1.6.4)? It includes the JavaFX upgrade mentioned above.

Hi, 1.6.4 works on Wayland.

Thank you Bisq :)
