Customising Grub, Plymouth, Lightdm and the Mate Desktop on Debian

A brief how to showing what I do to customise the look and feel of my Debian install.

Commands used:

1. Lightdm configuration:

Install slick-greeter

Add/uncomment the following entries in etc/lightdm/lightdm.conf:
greeter-session=slick-greeter
greeter-hide-users=false

Then save your preferred background in /usr/share/backgrounds

Create /etc/lightdm/slick-greeter.conf and add the following to the file:
[Greeter]
draw-user-backgrounds=false
draw-grid=false
background=/usr/share/backgrounds/nameof.jpg (or whatever you want to call it).

2. Grub configuration:

Use Gimp to rescale your image to 640×480 and save as a tga file
Copy tga file to /boot/grub
sudo update-grub

3. Plymouth configuration

Delete the word splash from this entry in /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT=
sudo update-grub
