Was running 3.8.17 and experienced this problem. Upgraded yesterday to 3.8.18, but still the same
On each reboot either only 2 of my 3 Displays are available, or when all 3 Displays are available, then my Onboard RJ45 Network device is not working, and I have to switch to Wireless
It is always the Display connected to my usb-c port which disappears - never my main laptop display or display connected to the onboard HDMI port.
As it is now, all 3 displays are working but my Onboard rj45 network interface cannot be brought up
~ ❯❯❯ sudo ifconfig | grep enp4s0 1
enp4s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
~ ❯❯❯ sudo ifup enp4s0
ifup: unknown interface enp4s0
Any suggestions/ideas to debug this ?
(64Gb RAM/ i7 Processes/17" Display, and 2x 27" external displays)
