Title:
Xorg crashes with a bus error in OsLookupColor when using a second
display
Status in xorg package in Ubuntu:
Incomplete
Bug description:
I'm using a Dell XPS 9380 ("developer edition") connected to an
external monitor via USB C.
I've been running Ubuntu 19.04 for months with an external monitor
with no issues. On upgrading to 19.10 xorg crashes with a bus error
within a few seconds or minutes of using the external monitor.
The xorg package installed is 1:7.7+19ubuntu12
The system is stable without the external monitor.
The crash is consistently repeatable and the stack trace looks very
similar each time.
