This looks like a lightdm issue more than xfce-session? If you switch to gdm does it work? This looks like it might be a duplicate of bug 903828 in selinux-policy. *** This bug has been marked as a duplicate of bug 903828 *** |
Description of problem: When a user confined with SELinux to the user_u context, you are unable to log into XFCE. Version-Release number of selected component (if applicable): xfce4-session-4.10.0-4.fc18.x86_64 How reproducible: Always Steps to Reproduce: 1. Create a user confined as user_u on Fedora 18. 2. Log out as current user and attempt to log back in as confined user. Actual results: Screen blanks for a second and you end up back at the login screen. Expected results: Log in to the system normally.

The first thing is the being kicked out and not logging in. The other issue is that there is no error message (for example "Access Denied") or anything before being punted back to the desktop manager.
