Public bug reported: Hi,
I think this is a regression... I had the exact same problem (system not going to suspend when LID is closed and external monitor plugged-in) with XUbuntu 19.04. Under Xubuntu 19.04, I was using light-locker and was advised to switch to power manager. This solved the problem. However, I recently upgraded to XUbuntu 19.10 and now, I get the exact same problem: if my external monitor is plugged-in, then closing the LID the computer does not suspend, it only switches the monitor external monitor to black screen (sleep?) for half a second, then switches it on again. See demonstration at: https://lufi.alolise.org/r/6Qo2m8r2t9#D1ZYe/CXqxMAcLD6UZvFlbYNMVfQESfr5j7vxg85MiI= light-lock says power manager is responsible for the PM config: https://lufi.alolise.org/r/TEn9o2m56q#WUJDAf/NYTbaLgbD/Z5WBQUwVE173dyx3lhSZZbNvf8= Xfce Power Manager is version 1.6.5 I've tried the solution provided in the following answer: https://forum.xfce.org/viewtopic.php?id=12970#p52468 With this the external monitor does blank/go to sleep, but the system does not go to suspend on lid close. It *does* go to suspend... *but when the lid is reopened!!!! I tried to remove power manager and switch back to light-locker. It does not work either. ** Affects: xfce4-power-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1855078 Title: Power Manager does not suspend computer on LID close if external monitor is plugged-in To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfce4-power-manager/+bug/1855078/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
