    Angry My 20.04 fresh installed ubuntu is totally slow

    Hello, I have installed ubuntu 20.04 next to my Windows10. After the boot screen where I chose Ubuntu I have to wait more than two minutes to get the loaded ubuntu desktop.

    I have read some forums and topics about the slow ubuntu, so I ran the systemd-analyze blame command and found that the plymouth-quit-wait.service has 1min 50sec loading time. What can I do? Is it so important that I cannot skip it?
    The windows 10 part is successfully loading in 19 sec. What do you suggest? How can I make my ubuntu faster? Is it possible? Thanks in advance!

    What is the average boot time on ubuntu? Is it normal that I have to wait more than 2 minutes?

    the result of the systemd command:

    Some small number of seconds. I rarely reboot, so I couldn't tell you exactly how many.

    The default timeout when starting/stopping services is 90 seconds, which I think is a bit long, but is configurable. I can't remember exactly where the setting is - it's a text file somewhere - but reducing that will mean that your computer is spending less time waiting for Plymouth to timeout during the boot process.

    The next thing you can do is try to work out what the issue is with Plymouth on your computer. That's the bit that draws the splash screen during boot; it's possible that it's not able to set your display for some reason, and that's why it's timing out.
    None but ourselves can free our minds
