Hello, I installed vglrun and turbovnc, but I can't get past the error below, what could be the cause of this error?
thankyou for support. vglrun /opt/VirtualGL/bin/glxspheres64 Polygons in scene: 62464 (61 spheres * 1024 polys/spheres) No protocol specified [VGL] ERROR: Could not open display :0. I also get the following error when I run this command by connecting with vnc and ssh. xauth merge /etc/opt/VirtualGL/vgl_xauth_key xdpyinfo -display :0 /opt/VirtualGL/bin/glxinfo -display :0 No protocol specified Error: unable to open display :0 'DRC' via VirtualGL User Discussion/Support < [email protected]>, 4 Nis 2024 Per, 17:17 tarihinde şunu yazdı: > The best reference is the VirtualGL User’s Guide and the TurboVNC User’s > Guide.
