Hi All,
I have a user on a compute cluster trying to run VMD remotely from head node. GLX is loaded by X on head node ...
I also have a linux desktop with GLX loaded but we continue to see the error of lacking GLX extensions using ssh with x forwarding enabled.
Any ideas?
-Henk

Siong,
At the console after typing 'startx', as root I can launch VMD and I see the gui windows. So on swallowtail all is fine. I ran the glxinfo command (output below) and GLX is loaded by X ...
So it must be in the ssh connection. Not sure. I have a desktop linux client with the same info as swallowtail. When I start VMD there I get the same error as you.
I'll ask the list.

Subject: RE: VMD & OpenGL GLX Extension
Hi Henk,
I typed vmd in bash and a few windows including two GUI for VMD should pop
up. I have set vmd up in my local windows machine and OpenGL is required,
which was installed along with cygwin. Not sure about Unix system though.
