I installed an encrypted version of Ubuntu on my PC. If I start my computer appears this login screen: 
I'm unable to type in the passcode. Nothing appears. Also if I type in the correct passcode and hit enter nothing changes.
I solved this Problem by pressing the restart button. Now this screen appears and I'm able to enter my passcode: 
Is there a possibility to get the second screen at normal boot?
I'm using Ubuntu 16.04 with LUKS. Im using Nvidias 367.27 graphics driver. My /etc/default/grub file looks like that:
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
GRUB_TIMEOUT_STYLE=menu
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
If you are missing anything just ask.
