Ok, now it's weird. I created a new user accout, so as to test whether it was system-wide or user settings-related. It worked fine (for this test and the further ones, I tried 3 logins).
I removed ~/.config/xfce from my user files (I'm talking about the usual user, not the new one) -> issue still happened. I removed all ~/.config/ from my user files -> no issue I put back all the stuff piece by piece, trying to log in from times to times. I had no issue and I finally ended up with all my former config back and still no issue ! In the end, I couldn't isolate the guilty config file. I suppose something was screwed in my panel config or something (which I believe is a bug in the first place since I don't remember messing much doing dodgy stuff with the command line), and while going through the process of isolating the bad file, I took the whole thing through a state where it got "cured". Sounds kinda silly, doesn't it ? Anyway, while the issue was almost systematic, it has not happened since. So long, bug. I guess I can close the report. I'll reopen if needed. Again, I know the information provided is not worth much to the developper, but please tell us (users) what else to provide to help in such cases. ** Changed in: xfwm4 (Ubuntu) Status: Triaged => Invalid -- [Xubuntu] No window manager at startup https://bugs.launchpad.net/bugs/495361 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
