Hello, I installed 4.4.8 and it works better but not perfect. I sometimes manage to plug a second monitor, sometimes it freezes when I turn it on. If the second monitor is plugged when the system boots, I often have errors at boot "intel_dp_link_training_clock_recovery" and "intel_wait_ddi_buf_idle". The system boots normally as soon as I turn off the second monitor.
I managed to have it work some times, but I don't manage to see what makes it work or not. But when it works, it works well. I have a HP Elitebook 840 with Intel® HD8 Graphics 4400. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1559308 Title: Plugging HDMI screen in causes system hang To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1559308/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
