Incredibly Slow Boot Time with New Mint 19 Installation (Solved)

Post by felemur »

I installed Mint 19 Cinnamon on my Toshiba Satellite L770D with a 128Gb Samsung SSD, and 8Gb RAM. Before Mint 19, I had Mint 18 Cinnamon on it, and before that was Mint 17 Cinnamon. When I installed Mint 19, I did a fresh install.

When I turn on the laptop, it quickly boots to the point where you see the Mint Logo with the dots below it, then it goes to a black screen for ... I'm guessing here ... about 5 minutes or so, then suddenly the login screen opens up.

When running, it is fast and flawless. There must be some way to discover what is causing this weirdly long boot time. BTW, this never happened with any of the Mint 17 or 18 series installs, and there have been no hardware changes since Mint 17 & 18.

(PS - I did a fresh Mint 19 Cinnamon installation on my Dell Desktop, and the boot time is seconds)

Run uname -r in a terminal. If it says 4.15.0-24 then reboot, after the bios screen/logo press shift to get into GRUB boot menu, select advanced, select a lower version kernel (likely you only have 4.15.0-20).

Assuming the boot now went fine, open Update Manager > View > Linux Kernels and remove the -24 kernel. Don't install that version again, wait until -26 or higher gets released.

Thank you! Fixed. Wow, that was fast. (and now so is my boot time)

One thing to note, I had to press Shift before the logo to get into the grub menu.

Also, I had 4.15.0-23, and using it seems to have done the trick.

Really appreciate your help gm10, and I also really appreciate the great people on this forum.

You're quite welcome. Glad it worked. -23 is fine, the issues are only with -24, and it doesn't affect every system, as you noticed. A fixed kernel is in the pipeline.

Just an FYI for anyone else:

After removing 4.15.0-24, an update for Linux kernel 4.15.0-26 appeared in the update manager. I thought, wow, version 26 is here, so I installed it. After I rebooted, I had the same looooong boot issue as before. When I went to the Update Manager to view the kernels, it had actually installed 4.15.0-24 again.

Hmmmm. :? Anyway, maybe when 4.15.0-26 is ready, it should say, "No, really, it's actually 26 this time" in the update manager. :lol:

That wasn't 4.15.0-26 but 4.15.0-24.26. You need to read these carefully. Basically as long as you see a 24 in it, stay away from it. :D
And I really don't understand why so many people get this one in their updates, anyway. It was removed weeks ago. The highest version my mirror is offering is -23.

PS: The next version based on what's currently in the pipeline will be 4.15.0-28.30, although that could still change (numbers can only go up).

What mirror are you using? I'm still seeing -24

Actually I just checked the source code for the Update Manager, this isn't about the mirror, this is a home-made problem, the Mint Updater simply doesn't care that the kernel was pulled by Ubuntu and installs it regardless. So this is actually a Mint-specific problem (I did submit a bug report at github, so hopefully this will get fixed).

Thanks so much for this! I was going bonkers trying to find out what was causing this issue and getting nowhere until I read your post.
