So, I was digging more into this and it appears not to be a hardware problem. People are reporting similar issues and how monitor is sometimes working and sometimes not.
Anyway, I also found a workaround for this. When I set my monitor to 30Hz refresh rate this problem disappears. I have a Dell P271Q and in the settings menu there's a 'Display' option. Setting MST to Primary will lock the refresh rate to 30Hz and it will also put the monitor into 'Multi Stream Transport' mode. Having my screen on 30Hz is a downside, but frankly I didn't notice the difference. Still, this is just a workaround. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1295267 Title: Windows change Monitor/Desktop after screen lock To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1295267/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
