I've replicated the problem. Started with a relatively clean Jessie, did the upgrade to Stretch, logged in to a panel at the top of the screen (ala Jessie). ran xastir. lxpanel went away. ~/.cache/lxsession/LXDE/run.log has some rather unhelpful error messages.
for grins, ran lxsession from the terminal window. Got a different style of panel at the bottom of the screen. ran xatir, got several "error in lxpanel: corrupted double-linked list". as part of the upgrade process I did an apt-get autoremove, which apparently removed a bunch of the development packages required for an install, since there are now .h files missing. did another apt-get update, only sees 2 sources (used to have ~20?) this update process is very suspect. not sure I have a working system anymore. IMO, if you have a burning desire to upgrade to stretch, stifle it. -Jason kg4wsv _______________________________________________ Xastir mailing list [email protected] http://xastir.org/mailman/listinfo/xastir
