Re: [VirtualGL-Users] Problem VirtualGL TurboVNC and Chromium

I have no idea.  If the X server is headless, then how do you even know
that it is starting up properly?  It may not be.  Check your X server
error log.

 Hi, I used your recommendation but I got the same results on both nodes
 
 [VGL] ERROR: Could not open display :0.
 
 
 I suspect that this error is produced because I don't have connected 
 monitors, keyboards and mice to the render nodes,
 
 
 I made a test
 In the server node pc1, I installed turboVNC, VirtualGL and Chromium were 
 already installed, 
 VirtualGL is configured answering NO to the three questions of 
 vglserver_config
 
 I opened a new session of TurboVNC on the pc1
 
 
 I connected remotly to the pc1 from a netbook with TurboVNC viewer
 
 I opened a console in pc1
 
 I ran
 cd /home/cluster1/cr-1.9/mothership/configs/
 python crdemo.conf atlantis
 
 I opened other console and I ran
 
 
 vglrun crserver
 
 I opened other console and I ran
 
 crappfaker
 
 
 here I got two results:
 
 If I had connected monitor, keyboard and mouse 
 The chromium example runs ok, it is not important if the monitor is turned 
 off or turned on
 
 
 If I didn't have connected monitor, keyboard and mouse
 I got the same error when ran 
 
 vglrun crserver
 [VGL] ERROR: Could not open display :0.
 
 
 Please If you know what to configure to avoid this error please help me, I 
 had just one monitor, keyboard and mouse connected to the appnode (pc5) of my 
 rendering cluster.

Please follow the procedure in the User's Guide, which includes
restarting the X server after running vglserver_config.

Yes, I did it
First intalled virtualgl with
rpm -i VirtualGL
init 3
/opt/VirtualGL/bin/vglserver_config

I answered no,no, no to the three questions and restarted the x server
with the command
init 5

Also I configured the /etc/ssh/sshd_config
enabled de X11Fordwading and disabled UseLogin
