Slow Boot time SSD Manjaro KDe


I installed Manjaro KDe today on a 2009 Dell Studio XPS 1640. I put in a new SSD so wanted to try a new OS and opted for Manjaro. I am liking the OS so far but boot times are almost 30 seconds. I calculated end user boot time using a stopwatch even though ‘systemd-analyze’ only shows 13 seconds. Also it takes around 4-5 seconds after entering my password to show me the desktop. I feel this is quite slow for an SSD. After reading some posts here, I can provide systemd-analyze and systemd-analyze blame data.

Would appreciate if anyone can guide me to solve this.

[viking@pradhyumna-studioxps1640 ~]$ systemd-analyze
Startup finished in 1.803s (kernel) + 5.751s (userspace) = 7.554s reached after 4.390s in userspace

What drive do you have? My computer boots up very fast on a Western Digital Green 240GB SSD.

To find your hardware you can run “inxi -F” in terminal

I have an A-Data SU650 120 GB SSD.

You could also check output of

systemd-analyze critical-chain

I feel that my system boots pretty fast with following result:

[xxx@xxx ~]$ systemd-analyze
Startup finished in 1.764s (kernel) + 8.879s (userspace) = 10.644s reached after 2.745s in userspace

Also, after a fresh install the file system is still initializing and baloo file indexer could reduce the performance in the begin as well. I think your times are OK.

If you don’t use encrypted partitions you could disable and mask lvm2-monitor.service by:

systemctl disable --now lvm2-monitor.service
systemctl mask lvm2-monitor.service

I have also a SSD and it takes also ~31sec. Starting at pushing the power button until displaying the XFCE Desktop (using a stopwatch).

Startup finished in 9.860s (firmware) + 1.673s (loader) + 1.931s (kernel) + 8.324s (userspace) = 21.789s reached after 7.887s in userspace

When systemd says 13sec and you count 30sec, then i would say it is the KDE Desktop that takes time to start or the UEFI that needs time to initialize the hardware. “ reached” doesn’t mean KDE has been started, but it starts a DE at this point (after 13sec).

So XFCE started in ~2-3sec for me and was ready.

Make sure GRUB_TIMEOUT (set in /etc/default/grub) is not set unreasonably high and stalling every boot.

Thanks. I would’ve thought it would be much lesser with a SSD though.

I have set it at 0. However don’t think it made much of a difference.

After editing /etc/default/grub it’s required to:

$ sudo update-grub

to apply the changes to the generated boot configuration.
