You should use SGD's Kiosk option and start GNOME directly or some other window environment. SGD provides its own X server for applications to connect to which is why it says an X server is already running. I think you can look at the default-shipped 'My Desktop' object for how your object should be structured.

Urgent help needed please. Guys, I am trying to connect a customer to Ubuntu desktop using SunRay Thin clients. I am running SRSS 5 and SGD 4.5. Ubuntu desktops are VMware VMs. Right now I am trying to present an SGD login page to DTU, have them logon and click on Ubuntu desktop link to launch the desktop. SGD server is running on CentOS. I have Ubuntu application object setup using ssh -X. For some reason I am unable to launch the display of Ubuntu desktop. Session starts, but nothing is displayed. I have done this before connecting to Solaris VM, but Ubuntu must have something different. The current error is an X error stating that an X server is already running. There is a sane way to request a new screen from X but I'm not super savvy with the desktop side of Linux so I'd have to do some digging. In theory, the startx binary should just claim the next highest screen number but that doesn't appear to be the case here. I think I need to figure out the proper commands to pass to the already running X server to get it to claim a higher screen number. I tried to do this manually and got a bit further (/usr/bin/startx -- :1) but it claims to not find any listening sockets. Alternatively, is there an easier way for me to have certain DTUs launch Ubuntu desktops? I know I can try to create a Kiosk session using Xnewt (I think) and use Other Info field to point certain DTUs to that session. Is this correct? If so, how do I do that? I have never created a custom Kiosk session. Thank you in advance for all your help! Please feel free to contact me if you have any questions. Thank you! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Vitaly Tsipris Systems Engineer
