  • Based on https://gist.github.com/mdziekon/221bdb597cf32b46c50ffab96dbec08a
  • Installation date: 16-08-2019
  • Additional notes based on my own experience
  • EFI boot
  • Ubuntu 19.04
  • This should work on any computer. Only the RAID > AHCI change described below and the device name for the nvme ssd drive are specific to this laptop.
  • The process describes a completely fresh installation with complete repartitioning, however it should work fine when Windows is already installed (eg. brand new machine with Windows preinstalled) as long as Windows already boots with EFI.
  • The process was conducted on Dell's XPS 15 9560 (2017) with specs:
    • CPU: i7-7700HQ

Brother DCP-7055 scanner on ubuntu bionic 18.04
View README.md

DCP-7055 scanner (brscan4) fix

The printer has always worked in Ubuntu out of the box.

The old driver page at the Brother website contains drivers that won't work on Bionic no longer though. You need to use a newer version provided here: http://support.brother.com/g/b/downloadlist.aspx?c=us&lang=en&prod=mfcj470dw_us_eu_as&os=128

The old page has the 0.4.2 version of the driver, but Bionic needs 0.4.5 dated May 2018 on that page above. Best to use the installer script at the top of that page (it will add a second printer you can delete, but fixes the scanner).

# I recommend you first install ubuntu-unity-desktop, do not clean off apt cache, then sudo apt autoremove --purge "gnome*"
# then install again ubuntu-unity-desktop without rebooting once and with a network connection. This gets rid of Gnome
# entirely except for what unity needs to function
# Run this if the background image on the login greeter for your user doesn't change as you change desktop backgrounds
gsettings org.gnome.settings-daemon.plugins.background active true
# This will install a patched version of nemo without cinnamon deps, then make it the default
