Just updated a few days ago and I can't get the second monitor to work properly. It just mirrors the laptop screen with the same dimensions & resolution. Going into System Settings > Displays doesn't show the external screen. Nothing turns up in Additional Drivers.
When I turn on the laptop with the monitor already connected, the monitor displays the boot options with the correct dimensions/resolution; it's only later at the login screen that it stops displaying correctly.
Thanks in advance for your help.
Edit: My touchpad click & two finger scroll don't work on some boots, this is also new with the update. Could these problems suggest a driver issue?
