You need to run terminator in an X environment. Make sure $DISPLAY is properly set

$ wslusc --gui terminator
[info] Create shortcut terminator.lnk successful

C:\Users\username\Desktop>terminator.lnk

Looks like DISPLAY propery is not set correctly by the underlying script:

$ pwd
/usr/share/wslu
$ export DISPLAY=SHOULD_BE_SET
$ . wsl-integration.sh
$ echo $DISPLAY
SHOULD_BE_SET
