Bug Description
Steps to reproduce:
1. Leave laptop unattended in a cold room with a warm cat.
2. Cat will sit on laptop keyboard.
3. Wait 1 hour.
4. Lightdm will become unresponsive.
Symptoms:
Due to excessive password input by cat, lightdm acts oddly. I try to hit enter to try the invalid password and then type in the correct password, but enter has no affect. The cursor is not blinking, and hitting backspace has no effect. Using Ctrl+a or using shift+Ctrl+left arrow doesn't select the whole password to delete it. Hitting capslock causes the warning symbol to appear or disappear. The mouse moves, but clicking on the settings icon, date, sound icon, or language icon has no effect. One person suggested seeing if the cat had triggered scroll lock, but toggling between ctrl+q and ctrl+s had no effect. Logging in on a virtual terminal still works.
Alternative steps to reproduce if cat is unavailable or uncooperative about being placed on keyboard (see attached pictures):
0. Glare at cat.
1. Restart lightdm.
2. Log in as a normal user.
3. Lock screen with ctrl+alt+l (I'm running Ubuntu 15.10).
4. Weigh self. Weigh self + cat. Find books approximately equal to 10 lbs, and various household items to simulate cat paws (I used two large nail clippers, a fat key, and a bottle opener).
5. Put items on keyboard, avoiding function keys, backspace, and enter. Place books on top of household items.
6. Wait 1 hour.
