[Bug 1897185] Re: login triggers suspend after update

[Tim Wetzel]

Additional observations:
1. This bug is interacting with another: where the "short name" of the user (the Home file name) rather than the full user name is showing up on the login screen. Usually the short name shows up on this machine when it is docked. When the laptop is being used by itself, the full name shows up. ONLY ONCE tonight has the full name shown up at login in the dock... and when it did, the machine did not suspend.
2. This bug is also affecting automatic WiFi connection. When the machine suspends and I press power again to resume it (on the dock), it connects to WiFi as it should. But on that one occasion where the full user name showed up and it did not suspend, it cannot find the WiFi network security credentials even though they are stored. Very strange.
3. In working with this tonight, the spinning ubuntu logo hang came back during login. Since I know that initramfs was updated shortly before the kernel and nvidia updates, I created a new initramfs image. I also had to update that new image explicitly with a second execution of the update-initramfs command. I turned the splash screen back off, and verified that refreshing the ramdrive has once again cleared the initramfs deconding errors.
4. So the changes to initramfs, to the core/kernel, and to the nvidia drivers don't seem to be getting along with each other too well.
I hope this helps.

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.
