[quote=“gortchak”]3)My PC is under MS Windows and I connect lxplus via Hummingbird(Exceed).

I haven’t used eXceed in years. I just tried gl/gltf3.C and it displayed fine using XMing-Mesa 6.9.0.31 (straightrunning.com/XmingNotes/).
I recently ran into troubles with another GL program and found that regular XMing doesn’t work (XMing-Mesa does as it’s specifically designed for OpenGL). The Cygwin X-Server does also work. All of these are free.

Ok, I think the problem clearly is not in ROOT, as soon as you are not able to start any OpenGL application.
[quote=“gortchak”]Xlib: extension “GLX” missing on display “lxplus226.cern.ch:25.0”.
[/quote]It has nothing to do with lxplus (aka x-client). It says, your X-terminal (aka X-server) can not accept the remote OpenGL client command. What is your X-terminal?
[quote=“cplager”]Ummm… I thought I said this three posts up. [/quote]Sorry . [quote=“cplager”]In case it wasn’t clear: Instead of eXceed, try one of the X servers I mentioned.[/quote]You need to install “eXceed 3D”. 'The basic eXceed does not support GLX protocol indeed

as I installed Hummingbird 3D several days ago but I’ve found that OpenGL in my Hummingbird was disabled. I’ve done Enabled and now
that tutorial example is woRking when I am on LXPLUS.
