Symptoms are the same as #1508146 (but I'm not sure it's the same cause).
alt+left/right sends me to another tty (terminal shell). Although I'm still trying to determine if its window manager / keymapper kind of issue or what. I use ubuntu because I don't typically like to get to this level. This seems to be a regression error, I installed updates yesterday (same day I noticed: Apr-11 and also updates on either Apr9/10). Also of note, (out of ordinary), I had to kill an out of control evolution-addressbook-factory-subprocess process using System Monitor. System lost a lot of window manager features and led me to switch tty to reboot.
