Today my system coredumped (4.8-STABLE from Saturday), I believe it's somehow
X11 related:
X11 crashed first (signal 11). I was running it as root (I know I shouldn't).
I didn't think about it and restarted X11. While it was starting, I had a look
at the console, there was a bright white message: issignal.
This shows up at X11 startup.
Then the system coredumped.
Below is more information. Is this a serious problem?
Please help me, I'm an inexperienced programmer and I can't do this alone.
