Xpra: Ticket #87: Error visualizing data in Visit

Hi,

yesterday I reported about starting VisIt under Xpra. With the -nowindowmetrics option, VisIt starts apparently OK (see #85), but when I try to display something I get the following error:

angelv@carro:~$ visit -nowindowmetrics

Any idea what could be wrong or if there is a workaround?

Thanks, Ángel de Vicente

You probably need some X11 display extensions which are not available in your xvfb implementation (which is /usr/bin/Xvfb by default), try using Xdummy (the example given has GLX extension - which may or may not be enough to run your application)

Also note that the GL extension it tries to load is 'NV-GLX', hopefully this won't be the case when you use Xdummy as this would not work. I don't know how badly the NV driver messes up with the GL setup.

Not heard back, closing.
