[Bug 1971054] [NEW] Firefox fails in VNC (not a snap cgroup).

[Andy Ruddock]

Public bug reported:

Clean installation of Ubuntu 22.04.
Installed xtigervnc-standalone-server and dbus-x11
Started VNC server with vncserver -localhost no -geometry 1366x768

$HOME/.vnc/xstartup is :
  #!/bin/sh
  [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
  xrdb $HOME/.Xresources
  vncconfig -iconic &
  dbus-launch --exit-with-session x-session-manager

>From another machine, launched vncviewer ip_of_vnc_instance:1
I get a desktop which is functional.
Open a terminal.
$ firefox

What happens:

Get error
/user.slice/user-1000.slice/session-5.scope is not a snap cgroup

Same error if I try safe mode.

What I expect to happen:

firefox window to open in VNC.
