Hello kortewegdevries, or anyone else affected,

Accepted lightdm-gtk-greeter into groovy-proposed. The package will
build now and be available at https://launchpad.net/ubuntu/+source
/lightdm-gtk-greeter/2.0.6-0ubuntu2 in a few hours, and then in the
-proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
groovy to verification-done-groovy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-groovy. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
  Ubuntu 20.10 Groovy Proposed: Lightdm-gtk-greeter coredump during boot

Status in lightdm-gtk-greeter package in Ubuntu:
  Fix Committed
Status in lightdm-gtk-greeter source package in Groovy:
  Fix Committed

Bug description:
  * Impact
  The lightdm-gtk-greeter often segfaults on VMs

  * Test case
  - start a xubuntu livesession in a VM and logout
  -> you should get a greeter to log in
  (or install xubuntu in a VM)

  * Regression potential
  the mlockall call was supposed to provide improved security but isn't working, it was already commented out some cycles ago in unity-greeter, upstream and it other distributions

  ------------------

  Upstream:https://github.com/Xubuntu/lightdm-gtk-greeter/issues/77

  This is one of the many core dumps on `journalctl` for a given boot
  (dumps multiple times before starting) :

  **See it on upstream bug report**

  [lightdm.log](https://termbin.com/eipz)
  [coredumpctl](https://termbin.com/chr2)
  [gdb_backtrace](https://termbin.com/645a)

  Current Behaviour:

  On boot screen blinks for 2-3 times (probably the segmentation fault)
  but eventually starts after 1-2 minutes.

  Expected Behaviour:

  Greeter would appear properly after boot.

  Note: Some other systemd services are also failing on proposed, not
  sure if related.
