Troubleshooting Horizon Agent on a Linux Machine That Is Not Responding

Horizon Agent that is installed on a Linux virtual machine is not responding.

Problem

The Horizon 7 for Linux desktop is not accessible, and Horizon Agent is not responding.

Cause

The Horizon Agent service might not be running, or the X session might not be active on the Linux machine.

Solution

1. On the Linux virtual machine, open a terminal window and stop and restart the Horizon Agent service.

   sudo service viewagent <stop/start/restart>
   

2. Verify that the X session is active.

   ps –A | grep X

3. Install the X11 Simple VNC server on the virtual machine and verify that the X session is active over VNC.
