How do I fix this error with gnome xorg. I'm just starting to use Ubuntu duel boot and don't know how to debug this problem. Xorg has changed recently and I am unfamiliar with the xorg that does not need the old config file and where to find the log files for Xorg.
I'm using NVIDIA-390 drivers. It says there is a bus error and I am unsure what to do.
