Comment 22 for bug 1453538

Interesting, qkiz. This is what I experimented

1. Edit /etc/default/grub

Change the line –

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”

to

GRUB_CMDLINE_LINUX_DEFAULT=""

2. update grub

sudo update-grub2

3. reboot.

What I got:
1) plymouth seems to be disabled, there is no purple splash. In fact, the screen never go purple, it:
2) screen display black when lightdm started, black, with only a white movable mouse pointer.
3) Here I can type my password blindly, then the normal desktop shows up.
