Hardware: Lenovo P50 Symptoms: This problem did not happen until I dist-upgraded from Fedora 26 to 27. If the laptop is connected to the dock during boot, I get the logs below and nothing further. I cannot shift desktops, log in, etc. Due to the configuration, I cannot remotely SSH in without changing the FW after loggi= ng in so I'm unsure about that behavior. If I boot the system off of the doc and then place it into the doc before logging in as a user, all seems to work well. I can then remove and re-seat= the laptop without issue. If I boot the system, log in and then place it on the doc, sometimes (I do = not understand the pattern), the second screen attached to the dock is not seen= at all (does not show under displays).=20 Same symptoms on numerous docs.=20 I am concerned that the nouveau errors seen are unrelated to the actual problems encountered.
