I think it was LibreOffice in all three cases. When I had this issue on a second machine, all it needed to log in to lxqt, print (successfully), log out again, log in to KDE and print again (successfully). So the "good" change that lxqt did was actually a persistent change that also "repaired" KDE. > I think print-manager contains the gui bits that lets you handle a > printer in a plasma desktop, but I don't think it tries to set anything > up on login. What package is that from? I am not aware of using any graphical printing interface. If I remember correctly, KDE 3's really nice graphical printer management capablities went away during the KDE 3 => KDE SC 4 "migration" and didn't return ever since. Is there a package I should have installed for graphical printer management in Plasma 5? > Other possibilities, but this is more like guessing/brainstorming: > - cups has some kind of security pattern where you need to register > specifically with logind / policykit in order to get printer access In that case, the "repair" done by lxqt shold not survive a reboot. > - cups has some subservices that needs to be invoked in a special way > (dbus activation of some sorts) that for some reason doesn't happen > in your case until you visit with other-desktop. Also, that doesn't explain the persistence of the repair. Greetings Marc -- ----------------------------------------------------------------------------- Marc Haber | "I don't trust Computers.
