we’re using Alma Linux 8.5 and have built an NVidia graphics card into our servers and installed the appropriate drivers. In order to be able to use the graphics performance remotely with TigerVNC, we have installed and configured VirtualGL. However, when starting our OpenGL applications, the following error always occurs:
[VGL] ERROR: Could not open display :0
Maybe you have a solution for me to fix this error.
Thanks in advance.
