Try: cat /proc/sys/kernel/core_pattern If it responds: | /bin/false then do: echo core >/proc/sys/kernel/core_pattern to re-enable core dumps. I don't know if that will be enough. My, I installed from beta a virtual machine using gnome, and now I'm running a "zypper dup", but besides being slow it is going well (1005/1005 packages). Something about a libinput bug: timer event debounce, unrelated to the current issue, I think.
