Sometimes the sddm-greeter-qt causes a core-dump.

This morning as i startet my Computer i got a core-dump. After i savely could shutdown it again, the restart worked fine.

This happens very rare, so its not easy to reproduce.

here is the journal:

It will help nobody unless it’s diagnosed and a solution is found, therefore your post has been moved to a dedicated Support topic.

Please provide system information as described (below).

Note also that code and command output is expected to be placed within a pre-formatted text box – not within a quote box.

Either use the </> button while in the compose window, or manually type two rows of three backticks and paste the command output between them; like this:
```
Paste code or command output here
```

Regards.

What follows is from a standard template.

Welcome to the Manjaro community

As a new or infrequent forum user, please take some time to familiarise yourself with forum requirements, and the many ways to use the forum to your benefit.

Note: By virtue of using the Manjaro forum you acknowledge and agree to follow Rules and Guidelines outlined; so, you really should read them:

Required Reading

Highly Recommended

Work with us, not against us

Be prepared to provide output from commands when asked. It is equally important to provide as much actionable information as possible in your first post, rather than simply indicating there is a problem.

Simply waiting for others to ask you questions can be counter-productive – typically, nobody has a at their disposal – instead, please help others to make informed suggestions based on information you provide.

System Information

While information from *-fetch type apps might be fine for someone wishing to buy your computer, for Support purposes it’s better to ask your system directly;

Output of the inxi command (with appropriate parameters, and formatted according to forum guidelines) will generate information useful for those wishing to help:

a) inxi command (long-form):

inxi --filter --verbosity=8

b) inxi command (short-form):

inxi -zv8

inxi man pages (Arch Manual)

Running inxi within a chroot environment

Add --color=0 to the long-form command, or…
Change the short-form command to inxi -zv8c0
