Changing Login Color
I didn’t really like the default shades of
purple that Ubuntu uses for boot-up, so I wanted to change them to a pretty shade of green.
Stuff that didn't work
I tried changing the other instances of the aubergine purple by changing one
of the instances of #2c001e, but to my knowledge, that did nothing.
To change the color of the login screen:
You know how there's a screen that appears before your lock screen? That
screen was still purple, so I wanted to make that green as well.
xhost +local: && sudo vim /etc/alternatives/gdm3.css
You can change the editor
to Emacs or whatever you like.
Go to the block that begins with #lockdialogGroup, and change
the hex color from
#2c001e to whatever you want. I’m using
When I boot up, there's a quick flash of purple that still appears, but
I haven't yet figured out why that is.
Go to the lines beginning with Window.SetBackground.
There’ll be two of them.
The default color on these lines is (0.16, 0.00, 0.12), which
corresponds to #2c001e.
Change this (on both lines) to whatever you want (these are ratios).
I’m using (0.04, 0.21, 0.13) .
sudo update-initramfs -u
That should be it!
