I've downloaded and burned the .iso file from Ubuntu page (Ubuntu 16.04.1 LTS), and burned it on USB with Rufus.

Now, I've already had Ubuntu installed, but because of this problem, I thought I'd reinstall it directly by Ubuntu instructions, since I didn't for the first time.

I've also reset the CMOS settings to default, I thought maybe something I've done on the PC while messing with themes and installing lots of stuff via terminal may've messed up with BIOS.

Now, I went through this procedure when installing:

  1. Try Ubuntu (I didn't install immediately, but through try mode)
  2. Install Ubuntu
  3. Download updates and third party apps
  4. Erase disk and install Ubuntu

And then all the other misc stuff (date, place, login info etc). I also set it to log me in automatically (no password).

When I rebooted the PC, I normally booted it from the HDD. But the thing is, the boot is super weird. It takes about 50 sec to boot.

This is how it goes:

  1. Purple screen
  2. Screen power saving mode
  3. Black screen with something written in the top left corner (/dev/sda1 something, I also noticed the word "clean")
  4. Ubuntu load screen
  5. Black screen (I think)
  6. Instant load of desktop (w/o animations, desktop just shows up)

I don't think this is how it's supposed to boot, is it?

What do you think about the issue? And how should I fix it?

  • Give us an estimate on boot time. The black screens can happen to appear on switching graphics mode, which is not uncommen. If you want more help attach the printout of dmesg -H to your question. Yet I believe everything went just fine. – db429 Nov 12 '16 at 17:47
  • Sorry. I think the whole time is around 20 sec. edit I was wrong, I checked with a stopwatch and it's 50 sec – Elisey Ozerov Nov 12 '16 at 17:55
  • If older laptop with slower HDD, that may be normal. But if newer system may be slow. What video card/chip? If nVidia or AMD you may need a driver. – oldfred Nov 12 '16 at 18:04
  • It's a desktop, and it's indeed old (7y). But before I installed Ubuntu, I had windows, which was yesterday, and it booted to login screen in ~15 sec or less. Now, after I installed Ubuntu, it's 50 sec. – Elisey Ozerov Nov 12 '16 at 18:09

The black screens are due to changes in resolution and often times also created by changing graphics drivers.

Plus as you choose on installation your system logs in automatically, hence no login screen.

Seems everything is fine.

  • When I had Windows (yesterday), it booted to login screen in 10 sec. No way skipping login screen takes ~40 sec. – Elisey Ozerov Nov 12 '16 at 18:07
  • Windows does tricks to bring up the screen faster than completing the boot. If you want to get to know, what takes the most time booting run systemd-analyze blame and add it to your question. – db429 Nov 12 '16 at 18:25
  • Well, this totals to 67 sec. Can I setup to skip some of these? I don't know what are they yet though – Elisey Ozerov Nov 12 '16 at 19:42
  • I guess there is not much to do, probably you can kick out plymouth, avahi, snapd and apparmor. yet each has its perfect reasoning for it's existence. lets keep it going here – db429 Nov 12 '16 at 19:52
  • Meh. What do you think this would look like if I had a 2x2.5GHz processor? – Elisey Ozerov Nov 12 '16 at 19:59
