Hi,

there is no separate cygwin or Subsystem for Linux here.

In user's homedir in file ".x2go\etc\sshdconfig" if you change the line:

Subsystem sftp C:/Progra~2/X2GOCL~1/sftp-server

to

Subsystem sftp internal-sftp

it works for one session. However, you can't change this permanently in 
X2Go client.
