I am using vncserver to connect to a CentOS7 machine in the network. In order to make use of 3D graphics accelerations I am using VirtualGL <https://virtualgl.org/>. So any OpenGL program needs to be launched with *vglrun * to make use of OpenGL.
This works like a charm but only if I log myself in on DISPLAY 0 and launch at least one OpenGL application beforehand. In other words: If I - reboot the machine, - directly start a vncserver and - connect to it with a client, no OpenGL application is working and I get the error [VGL] ERROR: Could not open display :0. As soon as I log myself in on DISPLAY 0 and start an OpenGL application the error does not occur anymore until the machine is rebooted again. My question: How can I run OpenGL applications with *vglrun* without first running an OpenGL application on DISPLAY 0 after rebooting the machine? -- You received this message because you are subscribed to the Google Groups "VirtualGL User Discussion/Support" group.
