Segmentation fault while launching cinnamon-settings

Hiya,

Fresh install of arch on my desktop, but I got a big problem with cinnamon : I can't open anything from cinnamon itself. I have absolutely no access to the settings panel and all.

Apparently, when the system try to do "cinnamon --version", cinnamon crashes.

[simon@azathoth ~]$ cinnamon-settings > dmp
/usr/lib/cinnamon-settings/cinnamon-settings.py:12: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.
  from gi.repository import Gio, Gtk, GObject, GdkPixbuf, GLib, Pango, Gdk, cairo

    from ExtensionCore import ExtensionSidePage
  File "/usr/lib/cinnamon-settings/bin/ExtensionCore.py", line 29, in <module>
    curr_ver = subprocess.check_output(["cinnamon", "--version"]).splitlines()[0].split(" ")[1]
  File "/usr/lib/python2.7/subprocess.py", line 573, in check_output
    raise CalledProcessError(retcode, cmd, output=output)
subprocess.CalledProcessError: Command '['cinnamon', '--version']' returned non-zero exit status -11
Segmentation fault (core dumped)

I have absolutely no idea why it does this. I also tried to install cinnamon-git, but it always fails to build cinnamon-desktop-git.

Thanks!

Re: Segmentation fault while launching cinnamon-settings

What is the backtrace from the coredump and what is in the journal from that boot?

Re: Segmentation fault while launching cinnamon-settings

Are you using nvidia proprietary drivers with a skylake cpu?

Re: Segmentation fault while launching cinnamon-settings

I got a GTX970 and a Intel Core i5-4590 CPU.
Technically the drivers are up to date

Re: Segmentation fault while launching cinnamon-settings

Can you post the full dmesg please

Re: Segmentation fault while launching cinnamon-settings

Hi, I recently solved the exact same problem by following the instructions for loading microcode by the bootloader. This is required for Intel CPUs. The instructions can be found in the wiki.

Hope this helps

Re: Segmentation fault while launching cinnamon-settings

Hi my microcode (I followed the procedure in https://wiki.archlinux.org/index.php/microcode) is up-to-date and I still get this error. My processor is Intel® Core™ i7 Quad Core Processor 6820HK  and my graphical card is NVIDIA® GeForce® GTX 970M. Could it be another cause than the microcode?

Thank you.

This thread should probably have been marked as solved and you should have started a fresh one.
Without more information all I can suggest is
https://bugs.archlinux.org/task/46064 is possible as you are using a skylake based cpu with nvidia its fix has not moved from testing to extra yet.

Re: Segmentation fault while launching cinnamon-settings

Here is more info:

$ gdb python
(gdb) run /usr/bin/cinnamon --version

produces the following output:

Starting program: /usr/bin/python /usr/bin/cinnamon --version
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/usr/lib/libthread_db.so.1".
  File "/usr/bin/cinnamon", line 1
SyntaxError: Non-UTF-8 code starting with '\x8d' in file /usr/bin/cinnamon on line 2, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details
[Inferior 1 (process 8667) exited with code 01]

Besides, my processor is so new (released in Q3 of 2015) that it would be very unlikely to need a microcode update to fix this problem.

Please help if you can.
Thank you.

Re: Segmentation fault while launching cinnamon-settings

I don't think that is a microcode problem.   I am going to suggest you start a new thread.  Include the information in the post directly above, and post the first few lines of /usr/bin/cinnamon.  I somehow don't believe that is a python file, but I've been wrong before.

In the mean time, I am closing this thread.
