How to make KDE boot up faster?

So last time I used Windows 7 but sadly Microsoft ended its support so I switch Linux Mint then I found Manjaro Xfce but I didn’t like it that much and then I found there are many desktop enviourments so I stuck with Manjaro KDE cause it has stable enough packages and it has the sweet sweet AUR which basically is the best place to get software. There was a problem tho I realised Manjaro Kde booted way slower than Window 7 I counted the times with a stop watch and its quite long Windows 7 took 13 seconds ish and Manjaro KDE took 61 secs. I even disabled the password to log in and its still very long anyway to fix this?


My Laptop Specs
Operating System: Manjaro Linux

Graphics Processor: Mesa DRI Intel® HD Graphics 3000

Edit : I have a ssd on this laptop

Post the output of:

systemd-analyze blame

With that, we can see what tasks are taking time in your boot process.

so I typed systemd-analyze blame into my terminal (konsole) and the output is

Hope this helps

Looks pretty normal.

If you don’t use snaps, you can disable snapd to save some seconds, but otherwise it looks pretty normal.

I use snapd so I can’t disable it, any other way to speed it up tho? I already made the grub timeout thing to 1 sec so 9 sec down on my boot up time boot its still quite slow. Will changing a display manager make it faster?

Not really.

Let me ask you this.
Do you really reboot your computer that often, that shaving off 15 seconds of boot time is gonna make you have time to do something else in your day?

ya but I just kinda wonder why is it so slow?

yes shaving off 15 sec won’t really matter at the end of the day but having nice boot times is a nice thing to havee

In my opinion, under 1 minute is not slow. :wink:

ok, im going to try configuring lightdm with my spare computer and try it and see does it work anyways its good to try a new thing anyways

If you don’t have LVM partitioning, I’d disable lvm2-monitor.service.

How do you disable it

sudo systemctl mask lvm2-monitor.service

And also while testing SDDM in my spare computer…the booting is so much faster about 1/4 the time to boot up compared to my laptop and keep in mine this computer uses a SD card to boot up and my laptop uses a proper SSD, so it’s not the SSD problem I must have f up something, and it’s slowing the computer down. I actually though the spare pc was going to lose because I have so much thing auto start applications on the spare computer and the computer has an Intel atom processor which is extremely slow. any idea how to fix it without going through a clean install?

Spare Computer boot times

Laptop boot times

so both of them as more or less the same applications because I test everything I think is sketchy on that machine since is just a spare computer

The laptop actually don’t have many apps I installed all I did was just change VLC for MPV (because it’s totally better than VLC) and Cantata for rhythm box. I also installed audacity and Popsicle (USB flasher made by system 76) and also I installed Nemo file manager and Xed text editor. I am SUS about Xed and Nemo cause there not native, and maybe they have bloat which slow down the boot times, but these applications are also installed on the spared computer so maybe not.

I beg your pardon?
Here on an almost 10-year-old T430 with SSD, Manjaro XFCE boots up to the login screen in 3.8 seconds. On the same computer, Manjaro KDE actually takes more than twice as long, 8.4 seconds. If I look at the hardware data of the TO, it is comparable to my X220 / T420. There XFCE takes 5.6 seconds and I cannot give any information about KDE , because it is not installed. But accept up to a minute - never.
Edit: I think upgrading the RAM to dual channel will be helpful.
