I have problems with gnome-settings. It doesn’t open when I press the icon. This is the error that is logged in the syslog log:

I would appreciate your help to fix it.

Ouch. Can you install debug symbols and run the app in gdb to get a backtrace?

$ gdb gnome-control-center
(gdb) backtrace
....
(gdb) quit

I did what you told me and it opens but I don’t know if it was the reason for the solution.

Thanks a lot.

No, the command was supposed to investigate the problem, not solve anything.

Settings probably started with a different panel which isn’t affected by the issue.

5

Where do I look at the gdb log? I have no experience with this. Could you give me any specific instructions on what I should do?

6

Gah, sorry. I forgot the run command :man_facepalming:

You run gdb with gdb gnome-control-center. You start Settings with run and reproduce the crash. After the crash, you type backtrace.

Here you are:

No, that didn’t reproduce the crash, that was running the app outside a graphical session (or in some way that prevents it from establishing a connection to the display system)

The problem has been solved, the configuration opens.

Thank you anyway
