[Bug 2106437] Re: monitors never dpms off when three present
I've also observed that the system crashes now when it never used to do so. I've had to disable the monitor from the configuration unless I need a third monitor.

None of the on-screen menus for the monitors are auto. There is no auto setting in fact. • monitor 1 is set to DP (lower left), • monitor 2 is set to DP (lower right), • monitor 3 is set to HDMI1.4 (center top) It will only dpms off if I turn off monitor 3 (HDMI1.4). My mobo has 3 monitor connections (DP1, DP2, HDMI). ** Attachment added: "3 pictures of the monitor on-screen menu" https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2106437/+attachment/5873955/+files/Photos-001.zip -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2106437 Title: monitors never dpms off when three present To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2106437/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Possible workarounds (copied from bug 1971434): * Configure the monitor (in its own menus) to not auto-switch inputs. * Change from HDMI to DisplayPort cables. * Disable HDMI audio output. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2106437 Title: monitors never dpms off when three present To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2106437/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

> Configure the monitor (in its own menus) to not auto-switch inputs. This means go into the monitor's on-screen menu and look at input selection. Make sure it's not configured to automatically switch inputs, but instead fixed on a single input port. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2106437 Title: monitors never dpms off when three present To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2106437/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2106437] Re: monitors never dpms off when three present
In the past I've tried to disable audio as Google was suggesting that was one of the issues. No joy. My computer only has the ports it has. I believe it was 2xHDMI 1xDP. I'm using the MOBO video (no special card). I'm not sure what the first item "Configure the monitor (in its own menus) to not auto-switch inputs" means. I'm happy to help with reproduction. It is very consistent on my computer. Tell me what to do. +L: all monitors go dark at same time. 20-30s later, 2xHDMI go to lock screen, followed by DP a few seconds later. This flips back and forth for a while until it finally stays on the lock screen with DPMS on. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2106437 Title: monitors never dpms off when three present To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2106437/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2106437] Re: monitors never dpms off when three present
This is related to events coming from one or more monitors, which the system might treat as a reason to wake up. Sometimes a monitor will add/remove audio support, or disconnect entirely, when going to sleep. And that can give the OS the impression that something important is happening which should wake the machine. There are plenty of bug reports about these issues but I'm not sure which one this is. ** Package changed: xorg (Ubuntu) => mutter (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2106437 Title: monitors never dpms off when three present To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2106437/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2106437] Re: monitors never dpms off when three present
If I could reproduce it myself then I would probably look at making Mutter ignore all monitor events for a second or two after it has been told to go to sleep. But if I can't reproduce the bug then I can't test fixes for it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2106437 Title: monitors never dpms off when three present To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2106437/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
