I've just installed ubuntu server 16.04 but it won't boot. Here's the only thing I get on screen:

lvmetad is not active yet; using direct activation during sysinit

lvmetad is not active yet; using direct activation during sysinit

/dev/mapper/server--vg-root: clean xxx/xxx files, xxx/xxx blocks

"xxx" are some large numbers I can't even use the command line so I'm stucked. Any ideas?

  • This is probably a duplicate of this. Add your own information to the question. If you have a live-usb you should have no problem accessing the files.

  • It is not a duplicate, since the original one shows a harmless message but boots, but this one has the harmless message but doesn't boot. Sep 26, 2018 at 22:24
  • The lvmetad logs shown are irrelevant to the issue, nomodeset is used to configure your video output, lvmetad is related to the storage. Sep 26, 2018 at 22:26

I managed to resolve this for my machines by adjusting the grub configuration like so:

In /etc/default/grub, change:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="nomodeset" Then add this line:

GRUB_TERMINAL_INPUT="console serial" Run sudo update-grub and reboot for the changes to take effect.

  • Thanks Kyle, fwiw this should be the accepted answer because it actually solves the problem. I discovered this answer 5 mins after posting a similar thread (of course) - feel free to post your answer in there, and I'll clean up my attribution post: askubuntu.com/questions/973339/…

Although I doesn't actually solve my problem, I managed to "bypass" it using another tty (Crtl-alt-F2) and now I can use my server
