I uninstalled the transformation pack, but the bootsplash didn't reverted back to default Ubuntu. T_T
I tried to do the manual terminal changing of it, and it worked halfway. The bootscreen when booting is still the (although awesome, I need to change) windows logo. But when shutting down or restarting, it worked.
You have to change default plymouth theme manually. You can do this by typing
sudo update-alternatives --config default.plymouth
in terminal and choose the number, where the/lib/plymouth/themes/ubuntu-logo/ubuntu-logo.plymouth
is(this is the default ubuntu plymouth theme). Now typesudo update-initramfs -u
in terminal and you have the default plymouth theme back.
