However, with 4.15.0-20-generic, when I power on the computer, the kde plymouth does not show the textbox to enter the root volume crypts luks password. The logo just stays there like in the attachment. If I uninstall plymouth and remove quiet and splash from GRUB_CMDLINE_LINUX_DEFAULT= && update-initramfs -u it boots in text- only mode and then can enter the password perfectly.
