Comment 11 for bug 593493

Multi-seat now basically works in the new lightdm 0.4.0, however there is a very annoying glitch. Whenever I log out of my gnome session on one of the seats the X server crashes. Logging out on seat :0 even causes both servers (on a dual-seat setup) to crash.

I confirmed this behavior with two different hardware setups:
1) Dual-seat running on an onboard intel chip and an ATI Radeon 5450 card (X command: "/usr/bin/X -novtswitch -sharevts")
2) Dual-seat on the same screen in different VTs (like in the old lightdm, switching with ctrl-alt-F[1-9])

Since it shows similar behavior on both setups it is probably hardware-independent. Additionally, the second setup did not crash in the previous lightdm version (0.3.7). I'll include the log files for both seats on the first setup. The actual crash output starts at line 20 (in both files).
