This is a bit of a bikeshedding thing IMHO, but I'm not entirely sure whether it's a good idea for a guest session to start screen sessions. I'll let Jamie/the security team have the decision, though.
But AFAIR lightdm kills all guest session processes at session close anyway, right? Then it's probably harmless to allow this. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1442611 Title: Guest session can't write on /var/run/screen Status in Light Display Manager: Triaged Status in lightdm package in Ubuntu: Triaged Bug description: I'm customizing guest sessions in Xubuntu 15.04 in my school computer lab and dicovered that I'm unable to open user terminal in epoptes. The main reason for this problem is that epoptes uses screen for opening client terminals remotely on server session, but screen is currently unable to write on /var/run/screen for guest sessions. Could you please review current apparmor profile for lightdm-guest- session so it can get write access to /var/run/screen?
