I installed Ubuntu with a fully LUKS encrypted LVM.
It works fine with one issue: After selecting Ubuntu in Grub while booting, the "enter passphrase to unlock disk" screen does not show up. I can (blindly) type my password into the black screen and it works. After a few seconds the normal boot stuff happens and everything is fine.
But I wonder why I get nothing on my screen.
The first 2-3 times after installation it worked as expected but at some point the over the last few days the screen stayed black. (I can't really say what I've done that caused it..)
