Title:
  Login screen missing, only black screen

Status in Ubuntu:
  Incomplete

Bug description:
  New version of plymouth (after 0.9.5git20210323-0ubuntu1) makes login
  black screen and does not return a picture. Only the mouse cursor is
  visible on the black screen.

  Previous plumouth combination of packages:
  libplymouth5_0.9.5git20210323-0ubuntu1_amd64.deb
  plymouth_0.9.5git20210323-0ubuntu1_amd64.deb
  plymouth-label_0.9.5git20210323-0ubuntu1_amd64.deb
  plymouth-theme-ubuntu-text_0.9.5git20210323-0ubuntu1_amd64.deb
  work perfect.

  In logs after black screen we have this nouveau errors:
  kernel: nouveau 0000:02:00.0: fifo: write fault at 000026c000 engine 00 [PGRAPH] client 05 [CTXCTL] reason 06 [PAGE_READ_ONLY] on channel 2 [003fc70000 Xorg[2075]]
  kernel: nouveau 0000:02:00.0: fifo: gr engine fault on channel 2, recovering...
  kernel: nouveau 0000:02:00.0: DRM: base-0: timeout

  I think one of these patches in package 0.9.5git20210406-0ubuntu1 breaks video system:
      - details-remove-separator.patch
      - details-update-status.patch
      - initramfsless-boot.patch
      - misc-changes.patch
      - ubuntu-default-devicetimeout.patch
