[Bug 1897185] Re: login triggers suspend after update

[Tim Wetzel]

This bug continues to recur even after a fresh reinstallation of Ubuntu.
After working through the installation crash (bug 1871268) by using the
latest daily image; trying unsuccessfully to get rid of the still
recurring initramfs errors (bug 1835660); and disabling the splash
screen to avoid the dreaded spinning Ubuntu logo hang during boot (bug
1872159); the system, when docked, still went into suspend immediately
after entering the login password during startup. This occurred on a
T570 with dual boot (Windows 10 and Ubuntu freshly installed from the
latest focal daily-live current image). Downgrading the nVidia driver
also failed: once I did that, the system wouldn't boot at all. It just
stopped at a blinking cursor on an otherwise black screen.

None of these things were issues until the middle of September updates;
and after the big 20.04.1 update about a week ago, things got really
bad.

Be advised that installing from an earlier version (in this case 20.04
images from May and June of this year) also does not work: these
installs fail on the same crash as the current 20.04.1 image (bug
1871268).

This problem of the machine, docked with an external display as primary
(laptop lid down), appears to be a recurrence of previous bugs that were
thought to be fixed. Please address ASAP. Thank you.

Title:
  login triggers suspend after update

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  Ubuntu 20.04's software updater just applied quite a few updates
  affecting grub and nvidia. The modules should show in the report just
  submitted. Also, updates to initramfs had just installed a few days
  ago. Kudos in that these updates fixed two login/startup issues: I'd
  been affected by the compression change for initramfs and had started
  getting the spinning ubuntu circle on the logon splash screen,
  apparently due to an nvidia driver conflict. I'd turned the splash
  screen to nosplash, and have now been able to set it back to splash.
  Both of those issues now appear to be fixed.

  BUT now when I start Ubuntu with the T570 laptop docked, lid closed,
  external display and keyboard via the dock: as soon as I enter the
  login password and press enter, the system goes into suspend. If I
  then press the dock power button again, the system will resume and
  proceed normally.

  It seems that the new startup modules don't realize that the machine
  is docked; and/or that it erroneously now "detects" the closed lid as
  a change in lid state during startup, triggering suspend. Prior to
  today's updates, this was not an issue.

  I would appreciate seeing this corrected. Thank you.
