TUTORIAL : How to install VirtualGL and TurboVNC on Jetson Nano

Hello. I done again the tutorial,trying to fix the problem that I have. Basically,suddenly when I’m doing something on my jetson nano,I lose the connection between the vnc server and the client. At the beginning I believed that the Xvnc process crashed. But it’s not true. What I did to understand what stops working has been to create an Ubuntu virtual machine on Ubuntu 21.04 with virt-manager and I created a script like this :

ssh -Y root@192.168.1.3 startlxde

basically I’m using the ssh port forwarding on a virtual machine to interact with the lxde desktop manager running on the jetson nano. And I found this :

as u can see turbovnc + virtual gl is still running on the jetson nano. But If I try to connect the vnc viewer to the server,it won’t connect anymore. This is what happens :

nothing. this problem happens often. Someone of you can imagine where could be the problem here ?

ping is working :

ping 192.168.1.3
