I’ve tidied this up with a proposal that I would like your feedback with. This replaces the current lock-screen with slick-greeter i.e. consistent login and lock screens.
logout and login. Try locking the screen via the panel options/Super + L, suspend/resume, closing the laptop lid. There is a new light-locker settings menu option for controlling how the lock-screen works.
To reverse after testing is a bit more involved - so please follow the advice below exactly
I tried out the new lock screen and it looks great. I tried it on two different laptops, and love that the lock screen is now the same as the login screen.
However, I am having a couple of issues on both computers. (Both are clean installs of 20.04). First, if I use light-locker-settings, the default seems to be to Blank Screen After 10 minutes. However, no matter what I change it to, when I log out and back in, it reverts to 10 minutes.
The second issue I have is that when I have light-locker-settings set to blank screen after 10 minutes and wait 10 minutes, it works properly the first time. However, after entering my password to unlock, if I wait another 10 minutes, the computer does not lock itself again. Instead, if I look in the light-locker-settings after the 10 minutes has elapsed, “Blank Screen After” has set itself to “never.”
This is consistent on both my computers. I didn’t know if I was alone in this. Aside from this, I absolutely love the change.
What this is proving is that replacing the lock screen is a very difficult business!!!
Ok, the only other distros that I am aware of that use light-locker is elementary and xubuntu.
So will need to have a look more closely what they are doing. First up is test installing xfce’s power-manager package to see if it’s that area that needs more investigation.
Ok. My conclusion on this is that light-locker is broken against the latest systemd
In addition, since the frequency on commits to light-locker is few and infrequent and that the last stable release is a few years ago, using light locker is not a viable solution.
Those projects using light locker are going to have to reevaluate their way forward.
I am closing this topic since the proposal hasn’t got a viable way forward due to upstream issues.
