===== drm_kms_helper =====
Got these errors after installing Devuan Beowulf on an old Toshiba laptop. Found answer [[https://askubuntu.com/questions/893817/boot-very-slow-because-of-drm-kms-helper-errors|here]].

  # nano /etc/default/grub

Add **video=SVIDEO-1:d** to grub command line:
<file>
GRUB_CMDLINE_LINUX_DEFAULT="quiet video=SVIDEO-1:d"
</file>

  # update-grub
  # reboot
