Executing Shortcut doesn't produce any visible output

Describe the bug
Executing the created Shortcut shows the Windows Hourglass cursor for a brief second before returning to the default Cursor. No other actions happen.

To Reproduce
Steps to reproduce the behavior:

• Create Shortcut

[artman41@DESKTOP-TQGCI07 bin ]$ wslusc -i `pwd`/idea.png -g `pwd`/idea.sh
[info] You choose to use custom icon: /home/artman41/idea/current/bin/idea.png. Processing...
[info] Converting png icon to ico...
[info] Create shortcut idea.sh.lnk successful    

• Execute Shortcut

Expected behavior
Application to load via X11 similar to a native app

Additional context

• This was tested in response to WSL Path is incorrect with Custom built Distro #138 being fixed in v3.2.0 (Environment has not changed since raising the issue)
• Executing idea.sh from the terminal loads the GUI as expected, whereas the shortcut doesn't have any visible effect
• Other applications such as gedit load when ran from the terminal but not when executed via shortcut

The 'target' of the shortcut is as follows

C:\Windows\System32\wscript.exe C:\\Users\\Tyler\wslu\runHidden.vbs C:\\\\\\Windows\\System32\\wsl.exe -d fedora -d fedora -e  /usr/share/wslu/wslusc-helper.sh "/home/artman41/idea/idea-IC-202.6397.94/bin/idea.sh "

Same issue here.

Further testing shows that the bug is due to the wsluc-helper.sh script setting the wrong value for the DISPLAY environment variable.

On the test system, the correct value for DISPLAY (resulting in 172.22.112.1:0.0 in my case) is obtained by:
wsl2_d_tmp="$(grep nameserver /etc/resolv.conf | awk '{print $2}')"
export DISPLAY=${wsl2_d_tmp}:0

However the script erroneously sets the DISPLAY (resulting in 192.168.43.50:0.0 in my case) value by using the lines in the script:
set +H
wsl2_d_tmp="$(eval "$ipconfig_exec" | grep -n -m 1 "Default Gateway.*: [0-9a-z]" | cut -d : -f 1)"
wsl2_d_tmp="$(eval "$ipconfig_exec" | sed $(( wsl2_d_tmp - 4 ))','$(( wsl2_d_tmp + 0 ))'!d' | grep IPv4 | cut -d : -f 2 | sed -e "s|\s||g" -e "s|\r||g")"
set -H
export DISPLAY=${wsl2_d_tmp}:0.0

A quick hack to get the script to work is to cut and paste the following two lines just before the last 2 lines in the script (i.e. lines "cd ~ || exit" and "bash -l -c "$*"):
wsl2_d_tmp="$(grep nameserver /etc/resolv.conf | awk '{print $2}')"
export DISPLAY=${wsl2_d_tmp}:0

Did not pursue further debugging to test why wrong path in script is being selected in setting the DISPLAY env var.

Hi @artman41 ,
Can you try to remove ~/.config/wslu folder? I will try to make a quick patch.

Hi @gerardvt ,
what system language you are using? Thanks

[gerardvt]

Just referring to wsluc-helper.sh bash script installed as part of wslutilities on ubuntu 20.04 wsl 2

[patrick330602]

@gerardvt Just to confirm, do you install the PPA version or the version that in the main?

[gerardvt]

Sorry I was not clear. I installed wslu via apt on ubuntu 20.04. Version details below.

$> apt-cache policy wslu

@artman41 I have fixed and the fix will be available for 3.2.1
@gerardvt Please use the Ubuntu official PPA instead of the Debian one for the latest release: https://launchpad.net/~wslutilities/+archive/ubuntu/wslu

@patrick330602 when are you planning to release 3.2.1? 😊

[patrick330602]

@romanlex There is a blocking bug I am currently fixing, hopefully it will be fixed today
