I'll try and describe the gdm login screen behaviour in more detail: 1. With no external monitor, the gdm login screen is shown as expected. This is true whether I unplug the external monitor after gdm is running or boot up without it plugged in at all. If I unplug the monitor, it takes a bit longer than I would expect before I see gdm's login screen, but it does eventually appear.
2. With an external monitor plugged in, the external monitor works correctly (it shows the gdm background) but the laptop monitor shows only a mouse cursor (or text cursor when entering a password). The background that it shows is whatever the last tty console was showing, so eg if I switch to tty3 and log in, then switch back to tty1, I see the mouse cursor and all the text left on the screen from tty3. This behaviour occurs on boot and also when I switch users or log out, ie whenever gdm's login screen should be visible. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1754218 Title: [regression] gdm 3.27 shows blank login screen on primary monitor when two monitors are connected on a hybrid intel/nvidia system To manage notifications about this bug go to: https://bugs.launchpad.net/gdm/+bug/1754218/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
