Not being a supported version yet usually means we shouldn't be discussing it here but also PPAs don't have anywhere for their issues to be discussed. And since it sounds like you're using a PPA version that will become official soon then I think it makes sense to discuss here. > If not, how can I best revert to the officially supported version? I'm not really recommending it right now, but if you wanted to then you could use 'ppa-purge' from: sudo apt install ppa-purge and then reboot and use the 'Additional Drivers' app to install a supported version. > while-display-is-off.txt This seems to show the kernel driver reporting the monitor is ON and has a valid frame on screen. So if you can't see it then that does point to a cabling problem. > I also ordered 3 new cables: Mini DP, Presumably Mini DP to full DP? It's unlikely these days the monitor would have a mini-sized DP input. I just assume it should have a full- sized DP port. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2125825 Title: External display does not wake after laptop lock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2125825/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
