() from /lib/x86_64-linux-gnu/libffi.so.8 but this is of limited usefulness since you don't have debug symbols for mutter available. The easiest way to get the debug symbols is to use: DEBUGINFOD_URLS="https://debuginfod.debian.net" coredumpctl gdb and type "bt" at the (gdb) prompt when the symbols have finished downloading. Or you could enable the debug symbols apt repository (see https://wiki.debian.org/HowToGetABacktrace#Installing_the_debugging_symbols) and install the libmutter-12-0-dbgsym package. We don't need any other packages for this particular crash. > core.gnome-shell.117.db5045b3be454eabaf40ab7634cdd15f.1720.1694258007000000.zst.gz In general we can't get a useful backtrace from the actual compressed core dump: that's something that the bug reporter needs to do. I tried to get a useful backtrace from this with debug symbols, but it doesn't match the result you sent and I'm not sure whether it really makes sense. Sharing these core dumps is also a privacy risk because they can contain private information, although in this case the crash was from the gdm login screen before you had a chance to enter any passwords, so it's probably harmless. smcv
