Hey guys, My Xorg keeps crashing. I am trying to figure out why. Only thing I get in the systemd journal that I can see is that Xorg dumped core.
So how do I analyize the core dump?
I think I have figured out the core dumps are in /var/lib/systemd/coredump
In there I have a TON of core dumps, however I am having trouble with them. For example the file core.Xorg.0.f33ac691a03742ffa2e25d15f3033f90.305.1429167238000000.lz4 is compressed I guess right? However when I try to execute
lz4 -d core.Xorg.0.f33ac691a03742ffa2e25d15f3033f90.305.1429167238000000.lz4 It just tells me
Error 44 : Unrecognized header : file cannot be decoded So what are these files? How do I get at them. Is there a different way to debug why my Xorg keeps dumping core??

You need to use the "coredumpctl" command to list these files and run them in gdb.

Thanks. That was what I needed. Got the file.
However not sure what to do with it because of course /usr/bin/Xorg doesnt have a debug symbols. Ugh.
No idea how I am going to figure out what caused this crash. It happens like 4 times a day, seemingly random.
