SSH connection was not possible during the blank screen after resume. Tried both WLAN and fixed. Apparently networking is down after resume.

I'm nevertheless attaching /var/log/Xorg.0.log.old in the hope that this would give additional information (not from SSH, this is from normal boot and login with 4.8-rc4)
