Help with Booting time

[Aditya1999]

I had installed Pop OS in my laptop (dual booted with Windows). However the booting took too long and I decided to reinstall Pop OS. Even now it takes a long time. I have attached a screenshot of the "systemd-analyze blame" command output. Please tell me how I can improve it. (I have an 8GB Ram with 8GB Swap, no SSD)

G'day @Aditya1999 and welcome to linux.org

To help us a little to help you, you could try copying and pasting output from Terminal into your Reply Pane here. You can do that with the Toolbar above where you type here - under the + sign are options including "Code" and "Spoiler".

So for example if I issue a command

cat /etc/fstab

I can then issue its output, by in Terminal choosing Edit - Select All, and then right-clicking choose Copy

chris@BeaverMATEdot1-SSD:~$ cat /etc/fstab
# <file system> <mount point> <type> <options> <dump> <pass>

UUID=e3161b45-fa4a-413d-b4b4-2ddd2348bee2    /    ext4    errors=remount-ro    0    1
UUID=C802-1F4A    /boot/efi    vfat    umask=0077    0    1
#/swapfile    none    swap    sw    0    0
chris@BeaverMATEdot1-SSD:~$

For something long such as log output or your systemd command, the Spoiler is good and you can give it a Title or not

Then it is easy for us to copy a line and say "No, this should read that", better than a screenshot of Terminal.

That being said

Can you give us the output of

cat /etc/fstab

?

Sure, I'll keep that in mind. Here's the output :

[adityapc@aditya-pc ~]$ cat /etc/fstab
# /etc/fstab: static file system information.

I have to go for my Aussie evening, momentarily, but to keep you going, and given you have 8GB RAM, I would first try editing fstab to "comment out" swap.

I don't have Pop OS, but being Ubuntu-based you could likely do it with gedit if you prefer GUI, or nano if you prefer Terminal.

For gedit

sudo gedit /etc/fstab

Change the line with swap in it to place a comment (#) at the start, so it becomes

#UUID=c4ae677c-23a8-46b4-881f-0ea6dc3600bb swap           swap    defaults,noatime 0 2

Save, reboot and report back.

Cheers

Thanks a lot, man! Booting time is certainly down. Here's the breakdown :

Spoiler: systemd-analyze blame

Startup finished in 6.711s (firmware) + 7.585s (loader) + 9.276s (kernel) + 20.901s (userspace) = 44.475s

I was also wondering if this is okay for a system like mine, ie, with an 8GB RAM and no SSD? Or is it still too long?

I'm also having the same problem with my newly installed pop os. Please help me out

G'day @Raju1990 and welcome to linux.org

The line

/dev/mapper/cryptswap none swap defaults 0 0

1. ... indicates to me that you have likely chosen at install to encrypt your Home partition. Is that the case?

2. How much RAM do you have?

3. What size is your Swap partition?

4. Can you print us the output, as was done above, of

systemd-analyze blame

?

Cheers

[Raju1990]

Thanks for your response
I have 4 GB of DDR4 ram and the processor is AMD A6
The swap partition consists of 3.91 GB

 

[wizardfromoz]

@Raju1990 thanks for the prompt response and the information.

plymouth-quit-wait.service is obviously the greatest consumer of time, on the face of it.

I am working on Kali issues at the moment, and then have to answer some questions and post a Thread on Linux Mint 20 changes, but I will come back to pop-os next 48 hours with more information.

Thanks for your patience.

In the meantime, if you have not already made the acquaintance of Timeshift, I would suggest you do.

You can read about it at my Thread here

https://www.linux.org/threads/timeshift-similar-solutions-safeguard-recover-your-linux.15241/

or Linux Lite have a good guide here

https://www.linuxliteos.com/manual/tutorials.html#timeshift

Before we implement any changes to your system addressing the boot time issues, I would advocate taking a full, on demand, screenshot with Timeshift, so that if anything goes wrong, we can roll back to where you were.

Cheers
