Additional info: When in intended setup (two monitors on one DP) the ASUS brand monitor flickers occasionally (not a nuisance)
- Connecting just the ASUS to the adapter (other HDMI port unpopulated) the monitor flickers repeatedly, indefinitely, often. This is regardless of which of the 2 ports it's on. I have attached verbose (drm.debug=0x05) kernel logs of this behavior - Connecting just the samsung (second external monitor) to the adapter works fine, and when going to powersave using "xset dpms force off" monitor&panel stay off, although the external monitor doesn't come on after resume (topic issue), confirmed multiple times So it seems like the ASUS is causing all monitors/panel to wake up ~15s after display standby. In the attached log, the monitor cycling on/off happens 5 times ** Attachment added: "cycling-onemonitor.tar.gz" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1527829/+attachment/4549558/+files/cycling-onemonitor.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1527829 Title: displayport MST external monitors don't return from sleep mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1527829/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
