I have very little experience with Linux. I'm trying to install the Unattended client on a Zorin OS 12 (Ubuntu) box but all I get is a black screen and the mouse does nothing when I connect to this Linux box from another PC. I do see the session in the SC control panel but, again, it displays a black screen instead of the actual desktop. It shows the user is root and the computer specs but the OS is listed as Linux (

I can, however, connect to other clients and control them from this Linux box.

I don't know where to begin. Can someone please help me troubleshoot?


java -version (previous):
openjdk version "1.8.0_111"
OpenJDK Runtime Environment (build 1.8.0_111-8u111-b14-2ubuntu0.16.04.2-b14)
OpenJDK 64-Bit Server VM (build 25.111-b14, mixed mode)

I followed these instructions to manually install Java 7u121 but I get the same results.
java -version:
java version "1.7.0_121"
OpenJDK Runtime Environment (IcedTea 2.6.8) (7u121-2.6.8-1)
OpenJDK 64-Bit Server VM (build 24.121-b00, mixed mode)

After more testing, I do see some screen changes in the SC control panel when I reboot this Linux box. It does show the login screen but it goes black once the desktop is loaded. Presumably, SC cannot interact with the desktop but it is connecting properly.

What's the output of the following command:


tail -150 /var/log/screenconnect-xxx

Where the xxx is your server's public key thumbprint. (you can use tab to auto complete after typing /var/log/screenconnect- )
