This used to work anywhere in the build phase (for older Xquartz and X11, anyway) but now I expect that using xvfb-run in a PostInstScript should work, since that is run as root, but will fail when run as fink-bld. > -- Oops. I think I misremembered the situation. I just tried using xvfb-run on my 10.7 machine (stock Apple X11) as my user and it failed. I guess we’ve always been relying on running it as root. It appears to suffice to run something relatively simple as root, like “xvfb-run ls”, so we could have the xvfb-run package add scripts to %p/etc/profile.d to run something trivial if /tmp/.X11-unix isn’t around. -- Alexander Hansen, Ph.D. Fink User Liaison ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
