[PD] Name of the "Pd console window" for [hcs/sys_gui] (Debian / ubilinux)

[Ingo]

Hi everybody,

I'm trying to move and resize the Pd console window with [hcs/sys_gui].
This used to work fine with pd-extended. The name of the console window used
to be "." in pd-extended.

With pd vanilla or purr-data this does not work. Probably due to the fact
that the console window is not named "." here.

Can anybody tell me the name for that window in vanilla or purr-data for the
use with [hcs/sys_gui]?
How can you find out what the name is?

I'm on Debian (ubilinux) 9.

Thanks!
Ingo
