Hi there, after all, this is great news! Thank you for this solution.
I am running Kubuntu natty 11.04 64bit. The installation was absolutely smooth and worked as in described in the HOWTO. Still, for some reason, the display export does not work here. I appended the two lines to my /etc/profile and rebooted. System comes up with gui (kde). But running applications with e.g. vglrun ./pslaunch reports: [VGL] ERROR: Could not open display :0.1. What have I missed? peter Am Dienstag, 3.
