OwnCloud Client not visible using xrdp to connect to Raspberry Pi

[Chucko]

I’m running OwnCloud Client 2.2.4 on a Raspberry Pi running Raspbian Stretch. All works fine but …

When I connect to the Pi from a Windows client using Windows Remote Desktop (the Pi is running xrdp v0.1.9-9) the OwnCLoud Client is not visible on the Remote Desktop! Neither the displayed client GUI nor the Notification Tray icon appear. I can do pretty much everything on the Pi using the remote desktop EXCEPT manage the OwnCloud client. I’m thinking this is an issue with the X-server display not being properly “exported” to/through the remote desktop display.

Any suggestions?

Did you have a look at this? Maybe a similar problem?

Client (GUI) does not start on Ubuntu 18.04

Beginning with Ubuntu 17.10 and now on 18.04 the owncloud client does not start. When clicking on the application or starting from cmdline, nothing happens. No error message, nothing, it just does not show up on the screen. But when I try it again using the cmdline (> owncloud &) a message appears: gui.application: Already running, exiting… But it does not run, no sync happens. The command line utility owncloud-cmd is working. Also, the clients on my other machines (Windows) are working well. …

Thanks for the suggestion, but I don’t think that’s the issue. The client starts and works just as expected when I’m sitting at the Pi with a display and keyboard connected. But even when I know the client is running, if I connect to the Pi using the Remote Desktop Protocol from a Windows host, the OwnCloud client is simply “invisible.” OwnCloud DOES get listed in Task Manager and with the “ps -A” command. But there’s no GUI on the Remote Desktop display.
As I indicated in my post, I believe it’s related to the X-session that OwnCloud is using being different from the session that is being “exported” to the Remote Desktop. So, I guess this may not technically be an OwnCloud issue per-se. But it’s maddening, and any help would be appreciated.
