Since my update to ubuntu 17.10, my gnome session is crashing everytime I lock the session and turn off the screen. https://www.nopaste.xyz/?b76a1d79191b2c5b#Gy5W5YlXS8/bpFXvmIQ0JXIdp0gX7TXGI0Byaz8AzB0= shows the syslog. This is not happening if I just lock the screen, without turning off the monitors, and it toes not happen with linux-image-4.13.0-16-generic.
