Title: Xorg crashed with SIGABRT in glamor_make_current() Status in xorg-server package in Ubuntu: Invalid Bug description: X crashes when logging into a KDE or GNOME Shell session; the SDDM greeter doesn't tickle the relevant codepath. Similarly, starting X and running xterm against works fine. It seems that glamor_priv is being unset somewhere? This is entirely reproducible, and didn't occur in 17.10. This system is somewhat weird, in that it's got both a Radeon and an NVIDIA card active in it, with displays connected to both.
