I'm on Ubuntu 14.04.4 LTS Trusty. This report applies to a few weeks back (was at least 14.04.3). If I recall, I did get the input field (but months earlier I got no input field onces in a while). Sorry, I forgot to report, but then could reproduce easily, since memory was low. If I locked the screen, then I couldn't get back in, but realized if I got into a virtual terminal and killed one of the chrome processes, to make some room, I could get in. Since then I've given up on the Chrome browser and went back to Firefox. I'm not saying this has happened always with Chrome or it is the cause (or Firefox the solution), just that it is an example of a program that can fill the memory so it can be done manually reliably in other ways to reproduce my bug. Sorry if this is not the same bug, do say if you want it reported separately. I find it very likely that memory low could be the same problem, even when the symptom is slightly different. 1. Do you use a multi-head setup? I think not.. I do have another monitor, have set up dual in the past, now the other is unconnected, and the mouse pointer does not go "off" to either side. If yes, using just one monitor fixes the issue? Not sure, I must work with 2 screens 2. Can you reproduce all the time? Frequently every day, under conditions above. 3. Do you use ldap? If yes, using gnome-screensaver fix the issue (see comment #115) can you still reproduce that? I'm not sure if I'm using ldap, I guess Thunderbird may be, we do have ldap at work, not sure I'm using it for a "address book". [Seems strange that ldap would be the cause.., what could I likely be using else, that uses ldap?] Not sure what #115 is telling me to do or if asking for this info: ps -ef | grep -i screensaver qwerty 32042 30834 0 17:09 pts/27 00:00:00 grep --color=auto -i screensaver 4.
