** Description changed: This problem is new in Ubuntu 18.10; it did not occur with 18.04. When my laptop, an HP EliteBook 9470m, with Intel Ivy Bridge graphics, comes out of resume, often the UI is unresponsive. Typically I get a black screen, a screen with just the GNOME top bar, or what the screen was showing before the laptop was suspended. The mouse cursor moves but the UI is unresponsive to input. If I switch VTs with Ctrl+Alt+F1, the lock screen shows, I can enter my password and after that my GUI session begins to work again, where I left off. The problem appears to increase in frequency when I add external monitors. It occurs on every suspend/resume if one or more external monitors (DisplayPort or VGA) have been used since the laptop was booted, even if they were present at boot, or subsequently removed. - If an extra monitor was plugged in while the laptop was turned off - (scenario: come home, put laptop in docking station with extra monitor - attached, turn on) then often the UI will still fail to respond after - switching to the lock screen with Ctrl+Alt+F1 and I will need to reboot - the laptop. + If an extra monitor was plugged in while the laptop was turned off (scenario: come home, put laptop in docking station with extra monitor attached, turn on) then often the UI will still fail to respond after switching to the lock screen with Ctrl+Alt+F1 and I will need to reboot the laptop. + --- + ProblemType: Bug + ApportVersion: 2.20.10-0ubuntu13.1 + Architecture: amd64 + CurrentDesktop: ubuntu:GNOME + DistroRelease: Ubuntu 18.10 + InstallationDate: Installed on 2018-08-13 (191 days ago) + InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) + Package: gnome-shell + PackageArchitecture: amd64 + ProcVersionSignature: Ubuntu 4.18.0-15.16-generic 4.18.20 + Tags: cosmic + Uname: Linux 4.18.0-15-generic x86_64 + UpgradeStatus: Upgraded to cosmic on 2018-10-19 (124 days ago) + UserGroups: adm cdrom dip libvirt lpadmin plugdev sambashare sudo + _MarkForUpload: True + mtime.conffile..etc.gdm3.custom.conf: 2018-12-05T11:18:35.863354 ** Attachment added: "Dependencies.txt" https://bugs.launchpad.net/bugs/1816896/+attachment/5240524/+files/Dependencies.txt -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1816896 Title: Laptop (HP EliteBook 9470m, Ivy Bridge) unresponsive after resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1816896/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
