Title:
Unlocking existing session often requires several attempts.
Status in lightdm package in Ubuntu:
Confirmed
Bug description:
# Context
* Computer with several X sessions opened.
* Users switching from one opened session to another.
* Lightdm opens new greeter, wait for typing password.
* User types password.
* Password is accepted.
* System closes the current greeter (screen gets black for an instant).
# Expected
* User gets back to their already opened session.
# Observed
* System immediately opens another greeter.
* User has to type password again.
# Reproducible
* Not always. At times, often, at other times, rare.
# Additional information
Users switch session via
dm-tool switch-to-user $OTHERUSER
but I guess bug appears with other means (like menu item like "lock screen",
etc).
# Information requested
