I was using Ubuntu Unity and today, I tried gnome desktop. However, I didn't like it. Then I removed gnome-desktop and gnome-shell packages. It has successfully removed but still my login screen's splash is the gnome splash.
it was the same for logout (turn off the computer) screen but I've changed it with this command:
sudo update-alternatives --config default.plymouth
then I selected the Ubuntu's default splash. But it was only affect to the logout screen. My login screen still has the gnome splash logo.
Also, my grub screen's color changed to gray from Ubuntu's default purple color (Canonical Aubergine color).
How can I revert it completely? I've tried all presented solutions on the askubuntu, related to my problem.
Edit: I've found a solution to login screen too!
Here is my commands and outputs:
anonymous:~$ sudo update-alternatives --config default.plymouth && sudo update-initramfs -u

The only problem has left behind this solution: grub screen's color. it is still gray.
