My computer has lenovo 300, with Intel Core i7-6500U and Ubuntu 19.04 installed. It takes so long to boot, like 3 or 4 minutes and sometimes I have to turn off my computer because it freezes with a black screen (before a normal starting). I don't know what I have to do. (This machine has 4 GPU).

1min 2.617s plymouth-quit-wait.service

29.087s systemd-journal-flush.service
28.746s dev-sda1.device

  • At the boot screen with the dots, typing esc should switch to a screen with text progress/errors. Do you see anything there taking a long time? – ubfan1 Jun 03 '19 at 02:14
  • After booting open a terminal and type systemd-analyze blame then copy the first screen of output (left click and drag mouse to highlight text, right click and select copy) and paste (right click - paste) into your question. – WinEunuuchs2Unix Jun 03 '19 at 03:50
  • @ValantinaCampos I have a work computer that does this but it's 100% due to the hardware. it's some cheap Dell. – tatsu Jun 10 '19 at 07:35

Assuming you are using Ubuntu 15.04 or newer, you can disable individual services by running this command in a terminal:

sudo systemctl disable service-to-disable

For example, if you wanted to disable snapd:

sudo systemctl disable snapd

(Do not include the .service extension when referring to a service on systemctl.)

Be careful when disabling a service, however! Some are critical and your system may fail to boot properly if disabled. Research each service listed to determine its importance.
