Control: tags -1 + patch upstream fixed-upstream
Hello Mladen Mijatov, dear Maintainer,
the first frames would be translated by addr2line to following [1].
This looks like the crash is caused by an invalid pointer pself/self
in function cc_display_mode_dbus_is_supported_scale [112].
This pointer is retrieved by cc_display_monitor_get_mode in [399].
That led me to this upstream bug [2] which got
already fixed in [3]. Either of the upstream tags 3.34.2 or 3.35.2
contains that patch.
Kind regards,
Bernhard

Bug#945375: gnome-control-center: Segmentation fault when selecting display on secondary GPU.
Hello Mladen Mijatov, if you still get this crash, maybe if you start it like below there would be more information about the crash. catchsegv gnome-control-center Alternatively you could install systemd-coredump and look at the end of 'journalctl --no-pager' if there is some debug information of the crash. Kind regards, Bernhard
