Hello, I updated my system (lightdm, cinnamon) and now slick-greeter keeps crashing.
This causes the system to loop between the boot TTY and an incomplete login GUI (only the mouse pointer appears briefly).
I can login via ssh and I disabled lightdm.service.
So I get the console login prompt and logs are not being flooded.
The journal states:
systemd-coredump[3201]: [LNK] Process 3174 (slick-greeter) of user 970 dumped core.
I’m not sure what happened here, besides updating I only did user’s stuff, like browsing and office.
IAC, switching to the LTS-kernel doesn’t change anything.
Any ideas?
Thanks a lot, Michael.
I checked logs and history, can’t find anything useful.
Maybe I’m overlooking something though.
Anyway, I’m running out of ideas and need a workaround:
Can I start Cinnamon from the console without lightdm?
Thanks a lot again, Michael.
Post the output of
$ coredumpctl info 3174
That will depend on whether you are running cinnamon on X11 or Wayland. If you are using X11, you have to first disable lightdm.
$ systemctl disable lightdm
After that, make sure you have xorg-xinit installed.
$ pacman -Q xorg-xinit
Open your ~/.xinitrc file and add this line to the last line of that file
exec cinnamon-session
Hi, I had to re-enable lightdm, so the PID changed:

ELF object binary architecture: AMD x86-64
xorg-xinit is installed:
$ pacman -Q xorg-xinit
xorg-xinit 1.4.2-1
It seems I’m using Wayland:
$ pacman -Q wayland
wayland 1.22.0-1
I’m not having an .xinitrc in my $HOME.
I can’t say if there’s any causality, but I barely touched the laptop since Friday and the coincidental event was a system update on Sunday evening.
The only package somehow connected to this could be cairo, according to pacman.log.
But reverting to the previous version (tried this yesterday) didn’t help.
Thanks, Michael.
You will have to create it yourself. Do the following:
$ cp /etc/X11/xinit/xinitrc ~/.xinitrc
This will create a .xinitrc file in your home directory with the default contents.
After that, open .xinitrc and replace all the exec lines in it with
exec cinnamon-session
Disable lightdm and reboot. Note that you will not see any greeter screen when you reboot. You will just boot into a tty. Login at the tty and run startx
Your cinammon session will start if you’ve done everything correctly.
Ok, done.
Indeed I can recognise the session as my session but it’s very garbled.
Icons and bars are not showing properly, or only show up with the mouse hovering over them.
Or just show the “tool-tip”.
Nemo, for instance, won’t start.
Libreoffice presents the splash window then throws an error and terminates.
Oh, that’s confusing … 
Can you post the output of

Make sure these lines appear before the exec cinnamon-session line inside your .xinitrc
Reboot and test.
Edit:
You can also check your .xinitrc file and see if it already contains the code snippet I mentioned above. You can remove the ones that are already in your .xinitrc and keep only the ones that are absent.
That didn’t change anything.
Curiously enough some programs run some don’t.
I think the pattern is native programs won’t start, 3rd party do.
The GUI itself still is garbled as described above.
BTW, the original xinitrc has some features I can’t explain and find strange.
See the bottom lines, PLS:
userresources=$HOME/.Xresources
usermodmap=$HOME/.Xmodmap
sysresources=/etc/X11/xinit/.Xresources
sysmodmap=/etc/X11/xinit/.Xmodmap
# merge in defaults and keymaps

To me that doesn’t make any sense.
I’m inclined to re-install xorg-xinit .
Note, I really would be interested to find out what went wrong here in the first place.
And why is it - seemingly - just me?
Why this hickup?
Since correlation is not implying causation and I can’t find any solid evidence that an update caused the trouble, how can I track down what causes slick-greeter to crash?
The default xinitrc file will launch twm (X11’s own window manager) instead of whatever desktop environment or window manager of your choosing. The default configuration of xinit does not assume you have particular desktop environment or window manager installed on your system. That’s why it launches its own window manger, twm.
That is unnecessary.
I’m not entirely sure why the crash occur on your system. There are several things you can try here. First of all, try to downgrade lightdm-slick-greeter using the downgrade utility from the AUR. After that, remove the ~/.xinitrc file (since you no longer plan to use xinit to start your desktop environment) and re-enable lightdm with systemctl. Reboot and see if slick-greeter crashes after the downgrade.
The cause could be anything at this point. It could be caused by a partial upgrade, which can be resolved simply by updating your system sudo pacman -Syu. It could also be caused by an upstream bug, in which case downgrading should fix the issue. It could also be caused by an issue with one of the packages that slick-greeter depends on.
We can start with the basic diagnostic methods first to narrow it down. But if we really want to go down the rabbit hole, we can analyze the core dump file with a debugger like gbd. Personally, I’d love to do this if I have the time.

Well my main-point ATM is, my work laptop is unusable and I’ve to meet deadlines.
(a very painful reminder to finally employ snapshots before updating!)
So far, the workaround (startx) isn’t working either.
I’m considering changing to the old GTK greeter as for a nicer workaround.
(found this: Want to experiment with Lightdm slick greeter? - which gave me the idea.)
And yes, I really like to drill down to the source of a problem, since I just can’t stand that kind of uncertainties of “not seeing what’s really going on” - even though I’m just a user and not a dev. Also to prevent such a problem in the future.
Esp. on an open system.
Like I mentioned above, try to downgrade slick-greeter to an older version first to see if the issue occurs.
Currently it’s v2.0.3-1 and I tried 2.0.2-1, 2.0.1-1, 2.0.0-1, 1.8.2-1 and eventually 1.5.4-1.
All show the same behaviour. So we may dismiss the idea of an upstream bug.
I put on the current version and again disabled lightdm.
I really need some sleep now, was up all night - thanks a lot IAC!!
Michael.
BTW, I did a full system upgrade two times meanwhile.
So we can consider ruling this out as well.
EDIT: JIC, I again did another full system upgrade which didn’t change anything.
Ok, lets see:
$ pacman -Qi lightdm-slick-greeter
Name : lightdm-slick-greeter
Version : 2.0.3-1
...
Depends On : cairo freetype2 gtk3 libcanberra libxext lightdm pixman python xorg-server xapp
Optional Deps : numlockx: enable numerical keypad on supported keyboard
Required By : eos-lightdm-slick-theme
...
cairo I already checked by downgrading to the previous version, because that seemed obvious.
Further, from a small script:
[2024-02-13T00:24:31+0100] [ALPM] upgraded lightdm (1:1.32.0-5 -> 1:1.32.0-6)
[2024-03-06T02:04:00+0100] [ALPM] upgraded pixman (0.43.2-1 -> 0.43.4-1)
[2024-03-06T02:04:05+0100] [ALPM] upgraded python (3.11.7-1 -> 3.11.8-1)
[2024-03-10T19:52:06+0100] [ALPM] upgraded cairo (1.18.0-1 -> 1.18.0-2) <---
[2024-03-13T13:23:25+0100] [ALPM] upgraded cairo (1.18.0-1 -> 1.18.0-2)
The reboot after (but not because of) update [2024-03-10T19:52:06+0100] was the one triggering the issues.
The last cairo update was because of my downgrade, which I didn’t need anymore at this point.
I don’t see anything suspicious here.
But that’s just my humble POV.
EDIT: I also tried older versions of lightdm - no luck (and no surprise).
This is probably a long shot, but try to reinstall gdk-pixbuf2 and shared-mime-info.
$ sudo pacman -S gdk-pixbuf2 shared-mime-info
Good Morning, thanks for getting back to me!
Done, but no luck.
May I ask for your reasoning?
