The method or operation is not implemented.

Hi, I think the message "not implemented" comes from the Dashboard. I tried to remove the "Local Datasource", to force the "remote datasouce"
Now the RDM does not start anymore.

Error:

./RemoteDesktopManager

Hi,

Your dps data source contains data that try to load an image in a way RDM Linux doesn't yet support.
I've added this issue to the our priority list for the next release.

In the meanwhile, you can delete the .rdm folder in your home folder to reset RDM to its default state.

Regards

i'ts the same problem:

What version of RDM Linux were you using when this error occurred?

Hi, I tried the enterprise version today, with this version the problem does not occure. thanks BR Christian

@garygsv 2020.2.1.0 (either free or enterprise) has a fix for this problem. Could you please confirm you are using the latest version and still reproduce the issue?

@christianneuhold Glad to hear it is fixed for you.
