Question 1) Monitor is plugged in on standard VGA connector (15 pin D-Sub). I guess it does not matter which monitor type. I have done it with a Ilyama ProLite G2773HS and a Samsung Syncmaster S24B350 monitor.
As soon as the monitors are configured, for example the external monitor as replacement for the built in LCD-display of a notebook, the system detects this configuration next time automatically and is switching to the proper monitor configuration, also for the login-screen. This behavior is fine, but does not help the first time, when no configuration was done (or it falls back to the starting situation). Question 2) I am using the P/N: U3DUALADA (barcode D16-00352296). Question 3) As HDMI monitor I am using the Samsung Syncmaster S24B35 Question 4) Using the i-tec adapter for the additional Samsung Syncmaster S24B350 monitor was working without any problems on Ubuntu 16.04. On Ubuntu 18.04 monitor configuration is not automatically detected. As work-arround I open the configuration->devices->displays dialog. If this dialog is open and I reconnect the i-tec adapter, the system offers now configuration possibilities. This must be done every time the adpater is connected to the system. A second minor problem when using this adapter is a mouse flickering effect. When mouse icon changes, it mouse icon disappears completely for a short time. When disconnecting the adapter system finds back to the default monitor situation without problems. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1773484 Title: Login screen not moved to used monitor Status in xorg package in Ubuntu: Incomplete Bug description: On Ubuntu 16.04 the login screen and system menu bar, ... is moved to the monitor where the mouse pointer is located. On Ubuntu 18.04 login dialog and system menues are restricted to the main monitor. So if you have a notebook with defect lcd display you can work with it using Ubuntu 16.04 and an external monitor, but you cannot work with Ubuntu 18.04, because you are not able to login!
