Please attach .xsession-errors. I can confirm this bug. Downgrading gdm fixes the problem. (In reply to comment #1) > Please attach .xsession-errors. can't login. Disable SELinux ( add kernel parameter selinux=0 ), this issue doesn't happen. So, find messages in /var/log/messages. ...

Is this bug selinux-policy issue? --- selinux-policy-3.10.0-21.fc16.noarch cc'ing dan walsh for comments Did pam_selinux get removed from the pam config? gnome-shell should be running under a user context like unconfined_t or staff_t. Dan: This is gnome-shell running as a GDM greeter session, no actual user is logged on. That's why the xdm_t context. Dan, recent versions of gdm use gnome-shell as a platform for the greeter. I would prefer that this be done in /var/run rather then /var/tmp, but not sure we can get gnome-shell to do that. My concern is users are able to screw around in /var/tmp and could cause xdm_t to do something bad. Should be fixed in selinux-policy-3.10.0-25.fc16 (In reply to comment #8) ....... > Should be fixed in selinux-policy-3.10.0-25.fc16 It semms not be fixed in this version. Downgrading gdm works around... Steve are you seeing additional AVC messages? Created attachment 522339 [details]

I'm not sure, here's the output from messages.
I seems to be fixed now with today's update. I'm experiencing a similar issue but SELinux is disabled. GDM wont start. Same error message on the screen, after upgrading from F15.
