There appears to be a problem with the DisplayConfiguration::power_mode flag in Mir.
I've added debug logging inside ms::MediatingDisplayChanger::update_input_rectangles to print the display configuration state. At startup, once unity8 starts, I see this output from USC: http://pastebin.ubuntu.com/16393116/ The power modes are wrong, which causes Mir to think the virtual display's geometry should be included in the input region. This patch is a quick fix, but not the correct one. http://pastebin.ubuntu.com/16393164/ Instead need to figure out why the power mode is being incorrectly determined when Mir reconfigures displays on unity8 connect. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580774 Title: mouse is getting stuck on a phantom edge To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1580774/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
