Xorg crashed with SIGABRT in OsAbort()

[aquatix]

I installed gnome-staging ppa to help me with hidpi on my XPS 15 (3200x1800 screen). I know this is unstable and in flux, but this error occurred on log in. Combined with the gnome settings daemon crashing makes for a bit of a wonky desktop.

Thanks for your help and happy to provide additional information!
