The 10.13: High Sierra Thread

[jamesbrobinson]

Now on developer beta 2 of macOS High Sierra.

Exactly the same issue. Screen is identified, mouse pointer works on the screen however it's an entirely black background, and I can't put anything on that screen.

Just installed the first public beta (which is the same as Developer Beta 2 Update 1) and I'm experiencing the same issues as everyone else - responsive mouse cursor but black screen.

macOS: 10.13 Public Beta 1 (17A291m)
Mac: MacBook Pro (Retina, 15-inch, Mid 2014)
DisplayLink Driver: 3.1
DisplayLink Device: Dell D3100

Black screen but registers in the Displays prefpane properly, and shows the mouse cursor.

Macbook Pro (Late 2013)

Still have black screen that is registering properly. Also plugging a display into the DisplayLink hub crashed the logged in session back to the login screen.

I just updated to Public Beta 2 and I have the same problem - if I connect a display to the DisplayLink dock something crashes and I get sent back to the login screen. Everything else in the dock works though - ethernet, USB, etc.

Hi,

If you are logged out when connecting the DisplayLink screen(s) then you've likely hit a macOS bug that is triggered by mirroring screens. It's probably the same issue it's currently happening with the eGPU kit.

On some systems mirror may be already set for the external screens so every time they are plugged in you'll automatically hit this issue.
A possible workaround is to delete all persistence information, so at the next plug in a default extended state can be chosen by macOS.

This is how to delete persistence information from Terminal. Please note that the following commands if entered incorrectly may delete any file on your system:

To clean user preferences:

rm -f ~/Library/Preferences/ByHost/com.apple.windowserver.*.plist

To clean global persistence:

sudo rm -f /Library/Preferences/com.apple.windowserver.plist

After a reboot the display settings will reset to default, which should be extending to the right and not mirroring.

Best regards,
Carlo

Morning Carlo! I followed this instruction to see what happens. The following result occours:

Running on 17A306f
Run command, disconnect DisplayLink device, restart the computer.
Computer boots normally with just the laptop and Apple Monitor plugged in over Thunderbolt.
Plug in DisplayLink with HDMI monitor attached.
WindowServer crashes, brings me back to login screen. Login screen is sky blue with a mild gradient, the background is not the standard background.
When trying to log in the WindowServer crashes and sends back to login. Repeat until you disconnect the HDMI and login screen returns to normal and login process is successful.

Carlo,

Many Thanks for the hints about mirroring! This was the last piece of the puzzle in order to get my DisplayLink adapter working once again after I upgraded to High-Sierra.

Have you installed version 4.0 of the DisplayLink drivers?
