I think it's very likely this is (at least in some cases) related to nvidia drivers.
I first got this problem while trying to fix a problem with ubuntu freezing after initial login described [here](http://askubuntu.com/a/760935/207604). I did "update" > "upgrade" > "upgrade nvidia drivers" as per the answer I've highlighted. Unfortunately this upgraded the kernel from .36 to .38 as well as upgrading nvidia drivers from 364 (I think) to 370, so I don't know which caused the problem. For anyone else with this problem: the only solution/work-around I found was to set GRUB_CMDLINE_LINUX="" GRUB_CMDLINE_LINUX_DEFAULT="" in "/etc/default/grub", then "update-grub". Not sure if both are required but that worked and I'm not touching it any more. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1359689 Title: cryptsetup password prompt not shown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kubuntu-debug-installer/+bug/1359689/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
