Slower boot time on newer laptop

Question

My boot time on my old laptop (asus k501uw) is 19s, but on the new laptop (hp pavilion) is 29s. It is not slow, but I wonder if it is possible to improve it. Thanks

EDIT: Ubuntu 22.04 LTS. Plus, screenshots of what systemd-analyze tells me about it.

This one is from the old laptop, that shouldn't boot faster than the newer one, considering that the system, configuration, applications is pretty much the same, but on older hardware.

EDIT 2: If I disable gpu-manager.service (systemctl disable gpu-manager.service), would that be wrong? I rather ask, since I don't know enough.

Answer 1

gpu-manager is responsible for switching between your graphics cards. So either

1. If you only have one card, you can disable it

2. If you want to control yourself manually which graphic card is active

It is not dangerous, so try it out:

sudo systemctl disable gpu-manager.service
sudo systemctl stop gpu-manager.service

Re-enable if Necessary: If you encounter issues after disabling gpu-manager, you can always re-enable it:

sudo systemctl enable gpu-manager.service
sudo systemctl start gpu-manager.service

check anytime which graphic card is active with

sudo glxinfo | grep "OpenGL renderer"

or

sudo prime-select query

switch to nvidia:

sudo prime-select nvidia

switch back to integrated graphics (Intel):

sudo prime-select intel
