[Bug 1038055] Re: graphics fail to initialise correctly, in kvm with cirrus graphics (after LUKS install)

[Stefan Bader]

I wonder whether that is to some degree related to the doings of the x
driver, too. When there still was a clash, I got a drm'ed console as the
fallback of lightdm not starting (slightly unusable because it chooses
quite a high resolution). I can confirm now that lightdm comes up
readable but the desktop won't start and switching to the vt causes
corrupted output. Switching back to vt7 and lightdm is possible (sure it
is not very helpful).

  graphics fail to initialise correctly, in kvm with cirrus graphics

Bug description:
  reproducible with ubiquity or alternate installer in KVM virtual machine:
  1) select lvm + encrypted instalation

  
  it fails to boot, in a way that I get "no video mode activated" and I cannot type the password in to unlock the drive.

  As a workaround, I had to:
  1) force reboot machine
  2) then grub options come up
  3) select recovery mode
  4) then I can enter the password using text interface
  5) resume normal boot

  Disabling splash, brings up text interface to unlock the drive &
  allows to boot.
