I recently enabled SELinux on my Debian Wheezy system, in permissive mode (I have confirmed that it is indeed operating in permissive mode). However, after the file labelling double-reboot, gdm3 doesn't seem to start properly. The SELinux setup details are in What's missing with my SELinux installation? (until there is a proper answer on that question, make sure to also check the comments on the question as they contain vital information).Specifically, gdm3 just sits spinning the doughnut wait mouse cursor. I can move the mouse around, but even several minutes (fifteen minutes and counting at the time of this writing), I don't get the login dialog box.Logging into a text-based shell and issuing startx with an old-school ~/.xsession does give me my usual desktop virtually instantly, so it's not a general problem with X, although it did give off a complaint about unable to start something that had to do with notifications. (That might be related simply to running multiple unrelated X client sessions on the same host.)I checked /var/log/messages and there's a small handful of selinux denied entries in there from during the boot, but nothing that seems related to either X or gdm3. I also don't see anything out of the ordinary in /var/log/X* or /var/log/gdm3/*. Considering that I'm running in permissive mode, SELinux shouldn't be getting in the way.How do I figure out what's wrong? How do I fix it? (I have no particular reason to use gdm3 other than that it's what was enabled by default on Wheezy; if the fix is use some other display manager, I'm perfectly fine with that, but if so I appreciate specific steps to change that.)The question Debian 7 black screen after loading OS appears to be about a similar issue but indicates there is no mouse cursor either, but it has no answers, no comments, might have nothing at all to do with SELinux (which I feel is likely to be the culprit here, somehow), and hasn't seen any activity for half a year.
