The pop-up message of the starting VM appears, then nothing. The VM gets started and the disk is whirring away, but the app never appears. If I launch the same app again sometimes both instances of that app appear one right after they other. Between those two invocations I might even wait until all the disk activity settles down and everything works fine. If for instance I use Qubes Manager to "update qube" the window almost never comes up the first time. The second time it will. If I start the template first and then select "update qube" it almost always comes up correctly, unless something is chewing up all the CPU or hitting the disk pretty hard. My issue seems to be related to too much activity of the AppVM's services creating enough lag to the system that the qrexec either times out or gets slowed down to the point of not completing the launching of the app. This is frustrating because after the first launch it seems to work better, so testing of why it isn't starting clearly needs to be planned in advance. Perhaps some resources get cached in memory the firt time so it starts that VM quicker, and thus the qrexec doesn't time out? I would suggest turning on the "Run in debug mode" option in the Qubes Manager's AppVM configuration so you can collect better logging information and see if that tells you anything. That is what I am planning to do tomorrow morning before launching anything. I had just turned it on for one VM this morning that sometimes acts up, and wouldn't you know it, it has not repeated that problem launching that VM the second time. Maybe tomorrow, or if I leave the machine alone for a while I might get it to repeat again. I think I will make a habit of turning on the debugging before launching any new VM's just in case I can catch it in the act of not acting properly. Thanks for pointing out where to turn the logging on. Questions though, I was attempting to look through the three logs of two different appvms but was not really sure where to start (was just shy of 6k lines). 1) Would posting the output to like a pastebin be useful/appropriate? 2) How sensitive is the info in the logs?

If there are dom0 logs that would be of use then please let me know. https://pastebin.com/LAXPSyBc What I see in the log that looks suspicious is: domain dead Failed to connect to gui-agent if it connected you would have seen something like: [ 18.849522] audit: type=1130 audit(1576676114.676:22): pid=1 uid=0 auid=4294967295 ses=4294967295 msg='unit=qubes-gui-agent comm="systemd" exe="/usr/lib/systemd/systemd" hostname=? addr=? terminal=? res=success' And that "audit:" message is not anywhere in your logs, so I think your AppVM's
