If I run a fedora based qube normally, all of those applications open and run completely fine, whether I launch them on their own or open files that would naturally use them as their default handlers. Gedit and Nautilus etc are perfectly willing to act at launch-starters for a fedora based qube, as long as that qube is a regular AppVM and not a DVM-template. It is *only* when trying to open those apps as launch-starters from DVM templates (such as fedora-26-DVM) that they refuse to open. Other apps like Firefox/Calculator open fine as launch-starters for fedora DVM's, and once open, I can run-terminal from the widget for that Disp8375 or whatever, and from that terminal launch Gedit or Nautilus or whatever, no problem. Only trying to start a new fedora based DVM with some specific apps (gedit, nautilus) fails, with the Disp7473 halting a minute or so after it initially launches, without ever opening the requested app. Debian/Whonix DVM's seem to have no such issue with any apps, at least that I've noticed. Only fedora. Honestly, it's a tiny bit of an inconvenience but at this point it's far more of an odd minor quirk than a major show-stopping issue, and thus I'm not sure I want to take up more of your or anyone else's troubleshooting time on something so relatively inconsequential. At the beginning I couldn't launch any DVM of any type no matter what, but I think that was more an available-memory issue than anything else. I appreciate all your assistance, as well as that of awokd. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
