Hello,

I have installed rocky linux 8.9 VM, where I have installed x2go server, Xfce desktop, to connect to the machine and installed mesa-libs. Testing OpenGL with the command `glxgears` I get:

`Error: couldn't get an RGB, Double-buffered visual`

I do not understand why I getting this error.

Here the outputs

```auto
glxinfo | grep OpenGL
Error: couldn't find RGB GLX visual or fbconfig

```

```auto
sudo lshw -c display

X2go has only mossy support for OpenGL/GLX. Try some vnc solution oder xrdp instead. Or this: [wiki:development:glx-xlib-workaround [X2Go - everywhere@home]](https://wiki.x2go.org/doku.php/wiki:development:glx-xlib-workaround)

Thanks for you reply. Do you have VNC solutions that work well on Rocky? I’m not expert on VNC I have only used x2go in the past.

I personally use TurboVNC ([https://www.turbovnc.org](https://www.turbovnc.org)) but TigerVNC (available from Rocky 8 repos) should work too.
