[Bug 1827702] Re: Upgrade 18.10->19.04, fail to boot

[Lucy Archer]

Don't know how xorg got selected - pretty sure the problem is with grub
or with the kernel, and seeing as the 4.19.20 kernel used to work, I'm
guessing it's grub

** Package changed: xorg (Ubuntu) => grub (Ubuntu)

Title:
  Upgrade 18.10->19.04, fail to boot

Status in grub package in Ubuntu:
  New

Bug description:
  I was using kernel 4.19.20 with ubuntu 18.10 and it was working fine.
  Upgraded to 19.04 and it now boots approximately one attempt every 5.
  Doesn't depend on the kernel I choose (I have both 4.19.20 and 5.0.0
  installed).

  If I use the default Ubuntu boot entry, I get a black screen (when
  normally it would prompt for the disk decryption password).  If I go
  to advanced options and choose a kernel (doesn't matter which one or
  whether it's recovery mode or not) then I get "Loading linux <version>
  ..." "Loading initial ramdisk ..." then nothing.  Ctrl-alt-del doesn't
  work, power key needs holding for 10s to turn off.

  I've followed the steps to get it to print more output (gfxmode text,
  remove quiet, splash, vt options) but it doesn't give any more debug.

  I don't know if the problem is in grub or in the kernel.  It's really
  odd that it works sometimes - I haven't spotted a pattern to that yet.

  I've attached a video of the boot process (I'd added an extra line to
  the grub script to make it print "Booting..." after loading the
  initial ramdisk, but that doesn't make a difference to whether it
  works or not).  Sorry about the focus - phone cameras don't like big
  blank spaces.

  Happy to try more debug options, but have limited time so might not be
  quick to respond.  Asus Zenbook 14, in case that makes a difference.
