LightDM/Slick Greeter settings menu won't load after Mint 18.3 MATE->Mint 19 MATE upgrade?

Post by darkstrike » Sat Jul 14, 2018 5:01 pm

With the latest Mesa update fixing the no-login issue a lot of people were having with the Mint 18.3-Mint 19 upgrade, I decided to try it on my spare desktop after it failed on my laptop last week and I had to completely reinstall Mint from scratch.

All has actually gone perfectly and I type this from my spare desktop running Mint 19 MATE! :D

A few tweaks here and there to get things how I like them and back to the way they were and all is well....except for the LightDM login. It works fine to actually login, but when I go to customize/configure it through the 'Login Window' option in the Mint Menu....well, the settings dialog just never appears?

If I run the command to launch the dialog from terminal (i.e. running "pkexec lightdm-settings" from terminal without the quotes), it will ask for my user admin password and then bring up the dialog that way just fine as it is supposed to, but not by simply clicking it in the Menu? Everything else in the menu seems to work fine?

Any ideas what is up here and how to fix it? Cheers! :)

Right click the menu entry and select Edit Properties, see what command it has configured for that.

Same command as mentioned above that I tried in Terminal - pkexec lightdm-settings - same command works fine through Terminal, but not when clicking the icon in the Menu.

I can't answer that. I take it Alt+F2 and running pkexec lightdm-settings doesn't work, either? Maybe apt install --reinstall python3, there have been some issues with that after upgrades from what I've seen.

Sorry for taking so long to post back! Tried reinstalling Python, made no difference!

I really don't know, for it to be failing silently without an error message is just weird. Try apt install --reinstall lightdm-settings as well I guess.

Yup - very weird because the command stored in the link in the Menu, when run in Terminal, seems to work fine! I had actually removed and purged lightdm in it's entirety and then reinstalled it already to no effect! :(

It's an odd one - video to show that I mean for peeps.....I just don't get why it works from Terminal, but not from the Menu...?
