Manual boot Time Encryption Too Long

My OS currently is KDE Arcolinux , and I have manually encrypted my hard drive, and it only takes about 7 seconds to get into the login screen after I enter the password.
I also have tested Bluestar linux, and it also takes about the same time to boot into the login screen, and they both are based on Arch!

I have been trying to install Manjaro with encryption for many months now. I try it every time Manjaro comes out with a new ISO, but get disappointed every time!

It takes 40-50 seconds just to get into the login screen if you encrypt the hard drive manually or encrypt it through the system. In other words it's not feasible to install Manjaro if you need to encrypt the hard drive. I have noticed other people have raised this issue as well in the past. Is this problem ever going to get fixed any time soon?

Do you get the password screen before or after grub in arcolinux? Because you can setup manjaro to decrypt the system in 7 seconds instead of 50. Password prompt before grub=long boot. Password prompt after grub=short boot time.

I set the boot with no encryption. Then the root with encryption. Similar to this.

I've done the same thing with Manjaro, but it takes for ever to boot into the login screen.

With this setup, the decryption should not take that long. If you have GRUB_ENABLE_CRYPTODISK=y in your /etc/ default/grub, comment it out and update-grub.

I switched it to comment GRUB_ENABLE_CRYPTODISK=y, and updated the grub, but that didn't fix the long delay. I'm not quit sure what you mean by comment it out.
Do you mean delete that line all together, and then sudo update-grub?
I've tried several different things, like deleting, ignoring the line, but none has worked so far. Could you give me specific instruction as how to do this?


Deleting it should also work. You can also prepend the line with # or replace the y in the end with n.

The issue seems quite odd. Can you post the output of lsblk and the contents of /etc/default/grub?

I tried both and replaced with the "y" with "n". Didn't make any difference. Then I deleted the entire line, and still no difference.
When I turn on the computer I get the "Attempting to dycrypt master key (40 seconds). Then you get to the second screen that says "Password is required to access the luks xxxxx volume. Then you finally get to the login screen 8 seconds later that where you an enter your user name and password. The boot is not encrypted at all. I don't understand why it's doing this only on Manjaro, and not on Arcolinux, or Bluestar linux.
Output of lsblk:
sda 8:0 0 223.6G 0 disk
├─sda1 8:1 0 700M 0 part /boot
└─sda2 8:2 0 222.9G 0 part
254:0 0 222.9G 0 crypt /
sr0 11:0 1 1024M 0 rom

Contents of the /etc/grub.
Please keep in mind that I deleted line 15 and 16 where had the grub-enable_crypodisk=y.

GRUB_CMDLINE_LINUX_DEFAULT="quiet cryptdevice=UUID=80f75ac1-3494-4596-98dd-788308b87d08:luks-80f75ac1-3494-4596-98dd-788308b87d08 root=/dev/mapper/luks-80f75ac1-3494-4596-98dd-788308b87d08 resume=/dev/mapper/luks-80f75ac1-3494-4596-98dd-788308b87d08 apparmor=1 security=apparmor udev.log_priority=3"

If you want to enable the save default function, uncomment the following

line, and set GRUB_DEFAULT to saved.


Preload both GPT and MBR modules so that they are not missed

GRUB_PRELOAD_MODULES="part_gpt part_msdos"

Uncomment to use basic console


Uncomment to disable graphical terminal


The resolution used on graphical terminal

note that you can use only modes which your graphic card supports via VBE

you can see them in real GRUB with the command 'videoinfo'


Uncomment to allow the kernel use the same resolution used by grub


Uncomment if you want GRUB to pass to the Linux kernel the old parameter

format "root=/dev/xxx" instead of "root=/dev/disk/by-uuid/xxx"


Uncomment to disable generation of recovery mode menu entries


Uncomment and set to the desired menu colors. Used by normal and wallpaper

modes only. Entries specified as foreground/background.


Uncomment one of them for the gfx desired, a image background or a gfxtheme


Uncomment to get a beep at GRUB start

#GRUB_INIT_TUNE="480 440 1"

Is this before grub? It sounds very much like what GRUB_ENABLE_CRYPTODISK=y does. I see you still have it in the bottom of your config. Remove it and turn sudo update-grub . That line is only needed with encrypted /boot

Please edit your post and quote terminal output properly by using </> button or insert the ``` above and below directly.

That worked! Thanks a lot for taking the time and walk me through this step by step. I really appreciate it. :slightly_smiling_face:


Could you tell me how to post the terminal the way you were saying? I can't figure it out!

I just did that, and it copied the whole thing in as a text!

That's exactly what was being requested. It's much easier to read this way. :+1:

I see!



I made the same experience and my system is not encrypted.
Arcolinux boots ultra fast (about 7-10sec) and Manjaro takes about 30 seconds until the login screen appears.
Strange but true
