Hello. No surprise: the top process is... lightdm-gtk-greeter. But I discovered that it is the case this morning (I will have to check again).
And I found at last an easy turnaround: the screen is refreshed correctly as soon as... I click with the mouse! I did not try before (I did not think it could be so simple). As a consequence, this bug is minor (as long as the click works - I will come back if it doesn't). Bye (I hope). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1610543 Title: After upgrading to 16.04, greeter does not handle double screen anymore Status in lightdm package in Ubuntu: New Bug description: Hello. I upgraded my laptop from 14.04 to 16.04 (Ubuntu 16.04.1 LTS) a few days ago. Since then, the login screen doe not appear anymore when I have a dual monitor (either connected to VGA port or docked via VGA or HDMI), both screen are black, showing only the cursor. When I switch back to one monitor (disconnecting the VGA monitor or undocking), the laptop turns to sleep (?!?). After waking it up, I got the screen, can login, connect back the second monitor and activate it (with xrandr). If I connect the second monitor when the computer sleeps, and wake it up, I then have the display, but without the login window (it appears as soon as I disconnect the monitor). The software lightdm is up to date (1.18.2-0ubuntu1).
