Problem occurs with up-to-date Ubuntu 14.04.2 on Dell Inspiron 7348. Ctrl+Alt+F2 and service lightdm restart does the trick (with work lost of course).
1. Do you use a multi-head setup? If yes, using just one monitor fixes the issue? No multi-head 2. Can you reproduce all the time? If a session is opened, yes, apparently. If I loggout of session before closing the lid, it seems to work correctly 3. Do you use ldap? If yes, using gnome-screensaver fix the issue (see comment #115) can you still reproduce that? No 4. Please consider posting /var/log/auth.log (at least part of it, should not contain sensitive information) OK, posted as attachement 5. Please specify the unity version thierry@thierry-Inspiron-7348:~$ dpkg -l unity Souhait=inconnU/Installé/suppRimé/Purgé/H=à garder | État=Non/Installé/fichier-Config/dépaqUeté/échec-conFig/H=semi-installé/W=attend-traitement-déclenchements |/ Err?=(aucune)/besoin Réinstallation (État,Err: majuscule=mauvais) ||/ Nom Version Architecture Description +++-===============================================-============================-============================-=================================================================================================== ii unity 7.2.4+14.04.20150316-0ubuntu amd64 Interface designed for efficiency of space and interaction. ** Attachment added: "As asked, my /var/log/auth.log" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1311316/+attachment/4402904/+files/auth.log -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity in Ubuntu. https://bugs.launchpad.net/bugs/1311316 Title: After locking screen there is no input field to type password for unlock Status in Unity: Fix Released Status in Unity 7.2 series: Fix Released Status in unity package in Ubuntu: Fix Released Bug description: *** IMPORTANT ** *** The fix is not included in TRUSTY.
