Hello,
I made a fresh install and after installing i3, I installed arandr, but it doesn’t work.
When I try to run it the output is:


(process:16752): Gtk-CRITICAL **: 10:32:47.904: _gtk_style_provider_private_get_settings: assertion 'GTK_IS_STYLE_PROVIDER_PRIVATE (provider)' failed

(process:16752): Gtk-CRITICAL **: 10:32:47.904: _gtk_style_provider_private_get_settings: assertion 'GTK_IS_STYLE_PROVIDER_PRIVATE (provider)' failed

(process:16752): Gtk-CRITICAL **: 10:32:47.904: _gtk_style_provider_private_get_settings: assertion 'GTK_IS_STYLE_PROVIDER_PRIVATE (provider)' failed
Segmentation fault (core dumped)

and dmesg says:


 5054.344709] arandr[16752]: segfault at 18 ip 00007fbd48b986ec sp 00007ffecf4d2a60 error 4 in libgtk-3.so.0.2404.8[7fbd48932000+347000]

I’m running Tumbleweed snapshot 20191202
uname -a:


Linux Think 5.3.12-1-default #1 SMP Thu Nov 21 07:21:43 UTC 2019 (a6f6081) x86_64 x86_64 x86_64 GNU/Linux

my version of arandr is 0.1.10-14.1 from X11:Utilities

If you can help me debug this or create a feasible bug report, that would be nice.

Thanks,
GS

Just create a bug with a description of your error.
I just ran arandr on a TW and don’t see anything that would be particularly unique about its stderr…

Likely needs to be compiled with current Python 3.7… maybe but necessarily updated GTK libararies but from what I see those might be pulled in by python libraries used…

Using a combination of ipdb, gdb and a few other tools I was able to determine where exactly in the arandr code the segfault happens. It’s a call to Gtk.Window(). If I try to run it manually:


import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
Gtk.Window()

it segfaults on the last line. I just did an update, so I should have the latest versions of everything available under TW.
