issues of how to share the desktop aside (i second the vote for VNC, but that won't do what you want in terms of using your already-running desktop remotely), GL apps are notoriously hard to do well remotely--hell, SGI invented a proprietary protocol to do remote-GL and even it wasn't particularly speedy, though at least it worked between two SGI's (caveat, last time i used this was in 1999.) if you're using hardware-accelerated GL to run scilab on your desktop, it seems highly unlikely to me that you'll be able to attach remotely and meaningfully interact with the display. non-GL programs should be fine once you get the sharing working. scilab itself has instructions for disabling hardware acceleration to get around rendering problems at the cost of speed (and if you end up using VNC, the suggestions here will effectively happen automatically since VNC is a software-only display, no hardware access used): http://wiki.scilab.org/Graphical_issues_with_Scilab_5.0 While windows may Just Work with remote view of GL-type programs, I can't believe the speed would be usable for something nontrivial. Is that really the case? _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
