Getting consistent messages preventing loading GUI apps for Ubuntu WSL2

Have latest W10 on old lenovo laptop.

• Enabled WSL2
• Installed Ubuntu - icon appears in start menu
• Installed ubuntu desktop, gtk2 engine, XcVserv, gedit, Firefox

Ran these in bash terminal, supposedly to show Ubuntu where X server is on W 10

export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2; exit;}'):0.0export LIBGL_ALWAYS_INDIRECT=1sudo /etc/init.d/dbus start &> /dev/null

At install I forced name because I didn't know how to setup a user account, so this is my "DOS prompt"

root@DESKTOP-0JQT19T:~#

I get...

root@DESKTOP-0JQT19T:~# firefox Authorization required, but no authorization protocol specifiedUnable to init server: Broadway display type not supported: 172.20.96.1:0.0Error: cannot open display: 172.20.96.1:0.0

Same happens when I run gedit.
