If your gear icon vanishes then that indicates some bug has happened and the system is unable to offer you more than one option. Usually the system will just remember the last option you chose in the gear icon, so future logins should all be Wayland.
Out of curiosity, can you please run 'lspci -k' and send the output? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1796528 Title: Problem with dual monitors Status in gnome-shell package in Ubuntu: Incomplete Status in mutter package in Ubuntu: Incomplete Status in xorg-server package in Ubuntu: Incomplete Bug description: Machine: HP 6735s with Mobile Intel® GM45 Express Chipset O.S. 64bit Ubuntu 18.04.1 LTS Gnome 3.28.2 I usually used an external monitor in Ubuntu 16.04 without any problem but I've formatted and maked a clean install of Ubuntu 18.04. It works ok when integrated monitor or external monitor are alone. If try to extend desktop to both monitors, then integrated display go black and only a blinking mouse arrow appears on it. External display is in closed loop trying to start, powering on/off the backlight, like system were trying to send image but crashing. When moving the mouse, arrow didn't go out of the integrated monitor. When I disconnect the external monitor, then image come back to the integrated monitor after some time. I've tried to edit "/etc/gdm3/custom.conf" to disable wayland and use xorg, but it's still the same.
