Then, another update this week, which included multiple systemd updates, restored/rebroke issue #2 above (the docking/undocking) issue. -- Libre Video http://librevideo.org -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct

I have an HP EliteBook 840 that also comes with an UltraDock, to which I've plugged-in two external monitors and I use in conjunction with the built-in laptop display. What Fedora distro are you using? Does this laptop have multiple GPUs? what GPU is it etc. You probably should file a bug against the primary GPU with the dmesg. Issue #2: When I undock my laptop while logged-in, Gnome Shell just crashes. When I redock after the laptop has been started when unconnected, one of the two external monitors start-up (the one connected by VGA), but not the one connected by a DisplayPort connection. And, recently (but not when I first started using this laptop with the dock, which was about a month ago), now when I start-up with the laptop docked and both external monitors connected, both external monitors will be active, but the built-in display will show nothing. Gnome Shell reports the built-in display is active, but will not display anything unless I deactivate it and reactivate it via the settings "Displays" utility. This sounds like MST releated but I can't say without more info. Dave. Completing my previous message with the requested information. Here is the GPU info as given by lspci: 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b) 03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mars [Radeon HD 8730M] I am running Fedora 20 on this laptop. From lshw output: product: HP EliteBook 840 G1 (D1F43AV) vendor: Hewlett-Packard version: A3009DD10303 So that I understand, should I file a bug against dmesg mentioning the Intel GPU listed above? And what other information do you need from me regarding the MST point above? I'm happy to provide whatever I can.

I am not sure how to tell which display is controlled by which device. It is Fedora 20. I can get you more details when I get back to work tomorrow. I'm happy to provide whatever information is necessary, but that is part of the problem, I'm not sure what is useful to help figure this out. -- Libre Video http://librevideo.org -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
