Sounds similar to bug 2066129 and bug 2066307, but currently we're blaming those on the Nvidia driver.

I have also tried your other suggestion, lowering the resolution to 1920x1080, and you're right - then the problem is gone. So I'll try with a different display cable (I'm now using the one that came with the monitor). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2067143 Title: ‘no signal’ after monitor sleep or monitor turned off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2067143/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Please try setting the external monitor to a lower resolution like 1920x1080. If the bug then stops happening it would suggest a higher quality display cable is needed. ** Tags added: multimonitor suspend-resume ** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Also affects: mutter (Ubuntu) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Status: New => Incomplete ** Changed in: mutter (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2067143 Title: ‘no signal’ after monitor sleep or monitor turned off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2067143/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2067143] Re: ‘no signal’ after monitor sleep or monitor turned off
I have the same problem: whenever my laptop sleeps two external monitors flicker/blink for a while and then show "no signal" message. Only one solution that sometimes helps is to open laptop lid or disconnect/connect monitors. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2067143 Title: ‘no signal’ after monitor sleep or monitor turned off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/2067143/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
