Bug Description

I'm not sure if this is a plymouth bug or xserver-xorg-video-cirrus, but if I install 13.04 on a kvm VM (via libvirt) with the cirrus video driver using the livecd (server install is ok) and choose to encrypt the entire disk, on reboot I get a flash of purple then it goes to a black screen. I thought it might be just that the prompt was not displayed, but typing the password simply echoes the password to the screen and does not open LUKS.

Any of the following works around the issue:
 * use the vmvga driver instead of cirrus
 * adding nomodeset to the kernel command line
 * removing splash from the kernel command line

If I remove 'quiet', then the boot stops (see attached screenshot).

With Lubuntu 14.10 and Radeon same problem. Work around by deleting the splash option in the Grub command line.

Edit /etc/default/grub
Change:
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT="quiet"

Now an old fashion text message appears and the passphrase can be entered.
