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... --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.4 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DisplayManager: gdm3 DistroRelease: Ubuntu 18.04 InstallationDate: Installed on 2018-08-07 (61 days ago) InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) Package: xorg-server PackageArchitecture: amd64 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=es_ES.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 4.15.0-34.37-generic 4.15.18 Tags: bionic Uname: Linux 4.15.0-34-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1796528/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
