[Solved] Unable to launch Chromium under Wayland/Sway

When I try to launch Chromium (Chromium-ozone), I'm getting following error:

 (chromium:368931): Gtk-WARNING **: 12:15:33.180: cannot open display: 

I tried to get more meaningful output like this:

 $ DISPLAY=wayland-0 chromium --no-sandbox --enable-logging=stderr --v=1
[485720:485720:1116/124819.831582:VERBOSE1:breakpad_linux.cc(2041)] Breakpad disabled

(chromium:485720): Gtk-WARNING **: 12:48:19.867: cannot open display: wayland-0 

My environment variables are the following:

$ printenv
SHELL=/bin/bash
COLORTERM=truecolor
I3SOCK=/run/user/1000/sway-ipc.1000.366847.sock
XCURSOR_SIZE=24

DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus
MAIL=/var/spool/mail/niklas
_=/usr/bin/printenv 

While trying to solve this error, some stated that this might be a permission problem (i.e. my home belongs to root), but this doesn't seem to be the case:

$ pwd && ls -la
/home
total 12
drwxr-xr-x  3 root   root   4096 Jul 25 03:21 .
drwxr-xr-x 17 root   root   4096 Nov 14 12:08 ..
drwx------ 10 niklas niklas 4096 Nov 16 13:07 niklas 

I've tried fixing this problem for some time now, at some point I also tried Firefox, but also couldn't get it to start.
Any of you have an idea what I could try next?

Re: [Solved] Unable to launch Chromium under Wayland/Sway

You have to have xorg-server-xwayland installed for running xwayland applications. Neither chromium nor firefox are native on wayland by default yet.

Re: [Solved] Unable to launch Chromium under Wayland/Sway

Oh ok, so the ozone version of Chromium just enables it to run via xwayland? I thought I wouldn't need xwayland as long as I'm using the ozone version.
Well, that explains a lot
Thank you for your quick help, I'll try it.

Re: [Solved] Unable to launch Chromium under Wayland/Sway

firefox works with wayland, copy the firefox.desktop file under ~/.local/share/applications

replace Exec=firefox-beta %u

with

Exec=env MOZ_ENABLE_WAYLAND=1 firefox-beta %u

once
