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?

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.

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.
