Xlib: extension "Generic Event Extension" missing on display "localhost:10.0"

This occurred with a fresh installation of ubuntu 9.10 (karmic). The machine had an ATI graphics card. The error listed below occurred with

ssh -x ipaddress

and then running gmsh on the remote machine. Firefox worked ok, forwarding graphics as hoped.

The fix was to install the restricted drivers for the card, an operation achieved from gnome on prompting that there were restricted drivers available.

Error follows:


Xlib: extension "Generic Event Extension" missing on display "localhost:10.0".
