Thanks for the tips. I'll look into upgrading my kernel.

Do you know what version of xorg is required?

Thanks!

Your dock is probably a DP MST device and so needs at least kernel 3.17 to
work properly. And the support is still wip, so might run into issues.
Iirc you also need an upgraded Xorg.

Dual/Triple Monitor with Intel HD 5000

[Jonathan Haws]

I am running the latest drivers on an HP Folio 1040 G1.  I am trying to setup multiple monitors via the 2013 docking station (dual display port outputs, single VGA).

I am running Xubuntu 14.04, fresh installation, kernel 3.13.0-43-generic from Ubuntu.

Things seem to be working okay, however I am having a problem with the two display ports.  The two monitors plugged into the display ports are showing up as DP2 in xrandr, instead of separate monitors.  The VGA shows up as a separate monitor just fine and I can configure it separately (though it only shows up when I reboot).

So, I have a couple of questions:

1. How can I force a refresh of the xrandr displays?  What I mean is, if I dock my laptop and don't see the VGA monitor show up, how can I force it to be detected without rebooting?

2. Is there any way that I can split the two display port monitors into separate monitors?  The only way I can get them to work right is to have them combined into a single display (i.e. a resolution of 3840x1200 instead of two 1920x1200 displays).  This is hard to work with since I can't maximize a window to just that monitor, rather it maximizes to the whole display.

Thoughts?  Any ideas on how I can get this configured?

I'm happy to send along any diagnostic information needed.  Just let me know what to send.

Thanks!
Jon
