Title:
Lock screen does not appear when screen locks
Status in gnome-session package in Ubuntu:
New
Bug description:
When I close the laptop lid, the screen locks, but when I start it up again,
instead of prompting me to enter my password at the lock screen, I appear to be
back in, even though I am not. The glitched session seems in between a vanilla
gnome session and my Ubuntu session. I can try to open applications with the
Ubuntu dock, but they will not open. The top bar doesn't have a log out or
settings, more like vanilla gnome in Debian. Sometimes white pixels will appear
at the top edge of the screen near this area. Sometimes the lock screen will
appear, but not as usual. The Ubuntu dock appears even though I haven't entered
my passcode yet. I should send screenshots. I wasn't always able to take
successful screenshots, but I have some. I don't believe this to be much of a
security issue, because I don't appear to be able to open any applications,
although it does show what files I have on my desktop. I am using a system76
laptop.

I expected a lock screen to prompt me to enter my password. Instead, it was
either missing, or it displayed along with the Ubuntu dock, which shouldn't
display on top of the lock screen. I also appeared to be using a modified gnome
session, even though ubuntu-session, but not gnome-session, is installed. I've
reinstalled ubuntu-session and ubuntu-desktop already. I know for sure this is
within the scope of ubuntu-desktop, because when I installed Kubuntu it stopped
happening. When I uninstalled kubuntu and reinstalled Ubuntu, it started
happening again. I've uninstalled some default packages, but noting
ubuntu-session depends on, so I'm not sure what the problem is.
gnome-power-manager is not installed, but I don't think it needs to be. It
reminds me of the issues linked below:
https://bugzilla.redhat.com/show_bug.cgi?id=713640
https://wiki.ubuntu.com/DebuggingScreenLocking/HowScreenLockingWorks#GNOME_Power_Manager
https://askubuntu.com/questions/453296/privacy-issue-when-waking-up-suspended-machine
Except logging in does not seem to work properly, and will log me into what
seems to be a gnome session, with all the application icons changed, and all
that.
