This affects me as well. Adding my scenario which is similar. I'm running Ubuntu 15.04 on a Dell XPS 13. I installed with the encrypted LVM option. Typically, I boot, I get the purple screen asking for my encryption passphrase, I put it in, then it goes to the standard login screen.
Now, I boot, I get that purple screen for the passphrase, but I can't seem to type anything. Even if I type my password and click enter, the screen doesn't change. I hold the power button to shut off and then I boot again. This second boot goes straight into Grub. I choose to boot Ubuntu, and it goes to a purple screen for me to enter my passphrase. This screen seems to be a low quality text screen however. I can type my passphrase just fine on this screen and then it goes to Ubuntu's login screen from there. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1386005 Title: Password not accepted graphical boot for encrypted root system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/1386005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
