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. I don't know where the problem came - from... gnome, intel drivers, graphic server... + 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.
