Hi,

After installation, when I start AFNI on WSL2 (Ubuntu 20.04), it gives me the following error:

Initializing X11 Error: Can't open display: 0.0
++AFNI is detached from terminal


I've launched VcXsrv before starting terminal and I've tried switching to WSL1 too (as advised in other threads).

The output of afni_system_check.py -check_all is following:
