Public bug reported: This is more or less a duplicate of https://bugs.launchpad.net/bugs/1716160 (i just copied the title), I'm opening a new bug as per comment https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1716160/comments/31.
I'm experiencing the same thing in Ubuntu 18.04: - Boot the laptop with external screen connected - Close the lid - The laptop continues to boot and reaches the login screen - Insert password - The laptop goes to sleep, i have to open and close the lid to make it wake up - Then it works without problems when i close the lid again This happens in the last days, maybe the bug appeared again with some update. Let me know if something can be done to help to debug the issue. lsb_release -rd: Description: Ubuntu 18.04.1 LTS Release: 18.04 apt-cache policy gdm3 gdm3: Installato: 3.28.3-0ubuntu18.04.3 Candidato: 3.28.3-0ubuntu18.04.3 Tabella versione: *** 3.28.3-0ubuntu18.04.3 500 500 http://it.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 100 /var/lib/dpkg/status 3.28.2-0ubuntu1.4 500 500 http://it.archive.ubuntu.com/ubuntu bionic-security/main amd64 Packages 3.28.0-0ubuntu1 500 500 http://it.archive.ubuntu.com/ubuntu bionic/main amd64 Packages ** Affects: gdm3 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1805699 Title: System goes to sleep with external monitor and lid closed after login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1805699/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
