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