Can't connect to Ubuntu 20.04 after reboot

Hi there,

I am having problems connecting to an Ubuntu 20.04 machine running TeamViewer 15.10.5. I am running the same version locally, but on Windows 10.

When the Ubuntu computer is started, I can see it appear in my Computers & Contacts list, but I cannot connect to it using either the IP address or its TeamViewer ID. It just shows "Connecting..." and nothing happens.

I have these TeamViewer options set:

- "Personal password (for unattended access)" is set up
- The "Grant easy access" box is checked
- "Access Control" is set to "Full Access"
- "Random password after each session" is set to "Keep current"
- "Incoming LAN connections" is set to "accept"
- The device is assigned to my account

...are there any relevant settings I'm forgetting?

If I physically go to the Ubuntu computer and login, I am then able to connect with TeamViewer from my PC. If I lock the Ubuntu screen, no problem, I can still login remotely. The problem only returns if I log out of Ubuntu (or reboot).

Another alternative I've found is to connect first using Xrdp + Windows Remote Desktop. This seems to wake something up on the Ubuntu machine. Then I can close the Xrdp connection and TeamViewer will now be able to connect successfully.

Interestingly, the computer seems to have two different TeamViewer IDs, depending on whether I login to Ubuntu in person or using Xrdp. I have tried both IDs trying to test the connection, both just hang until I first login as described.

If I check teamviewer info in the terminal I get:

TeamViewer 15.10.5 (DEB)

grep: /opt/teamviewer/config/global.conf: Permission denied
TeamViewer ID:  ***(nothing shows up here)***
Try restarting the TeamViewer daemon (e.g. teamviewer --daemon restart)

My /etc/gdm3/custom.conf file has "WaylandEnable=false" uncommented.

Any suggestions would be much appreciated!
