I have been facing this issue since yesterday, but basically at some point the system becomes insanely slow, and the restart and shutdown options disappear from the menu, tty3-7 dont work, it freezes at the shutdown -now command(at which point I just manually cut the power(bad Idea I know)),
but today I stuck around as my system got insanely borked, eventually freezing up and giving me the screen above. the problem shows up after I wake it up from suspend but not always: My system specs:

here are the journalctl entries that I think are relevant

and this is from when it happened earlier in the day
Old isn't necessarily bad. Also, as far as I can tell, distros are still patching 1.32. Based on my personal usage of LightDM and the fact that the project is still developed (based on commits to main), I'd say it's more of an "if it ain't broke, don't fix it" dynamic. As for security, the active development suggests the developers would respond if there was a vulnerability - a big if, considering its last CVE was in 2017.
Personally, I love LightDM - it has just enough features while mostly sticking to its name (I mean, you're probably using GTK anyway).
