I'm currently facing this issue on Ubuntu 16.04 too, on a GTX 980 with nvidia-364 driver (tough its the same on all versions I tried).
I can boot with fail safe graphics mode, but not normally. Trying to fix this with GRUB_GFXPAYLOAD_LINUX=wxh or GRUB_GFXPAYLOAD_LINUX=text has no effect, I'm left with a passphrase entry screen that displays all entered text on the top left, entering my passphrase here does not work. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kubuntu-debug-installer in 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 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
