Public bug reported:
$lsb_release -rd
Description: Ubuntu 18.04.3 LTS
Release: 18.04
Today I ran an apt update of my WSL2 Ubuntu 18.04.2 LTS installation on
Windows 10 insider build 19037.1. I then noticed when I launched the
WSL2 Ubuntu shell that it took about 38 seconds to get a shell prompt.
This was not an issue until after I did the update. After some
troubleshooting I found out this delay was because of wsl-
integration.sh, that the wslu update appears to have added. The
following two commands:
env DISPLAY=${WSL_HOST}:0 xvinfo
env PULSE_SERVER=tcp:${WSL_HOST} pactl info
in this script are both timing out on my computer. Because both commands
are timing out, that accounted for the 38 seconds it took to get a shell
prompt.
In my case, my WSL_HOST IP was 172.24.144.1 and so I ran these two
commands:
env DISPLAY=172.24.144.1:0 xvinfo
env PULSE_SERVER=tcp:172.24.144.1 pactl info
and sure enough it took a combined time of about 38 seconds for them to
timeout. This is only an issue when running Ubuntu in WSL2, not WSL1.
WSL1 launches fine. In the case of the my WSL1 instance, the WSL_HOST
appears to be null when running your script, so it assigns localhost to
WSL_HOST, and both of these commands timeout without delay.
