Suspect buggy KVM as I've had other unrelated issues with this box in the past. For now I'm doing two things:
- Using Synergy to share my keyboard/mouse/clipboard. For those of you not gaming (why are you using passthrough if you're not gaming?) Synergy is ****in' stellar. Essentially just move your mouse to the edge of Dom0 and it'll show up in DomU. Synergy however, does not play well with DirectX/DirectInput.
- Writing a script to trap SOME EVENT in DomU which will indicate that I want to re-attach my USB devices back to my Dom0 (like a soft KVM).
Makes sense. You're passing through the audio from your Radeon HD card though aren't you? In which case you're only getting an HDMI output? Same here. Works fine except that my speakers are already attached to my Dom0. I plugged my DomU monitor's analog output into my Dom0's line in which worked just fine and will probably go back to this, but this is a hack that doesn't work for everyone (ie: anyone without HDMI). I want a boxed solution we can share with non-haxor types.
Also, as for using the VNC input. Works .... okay for doin' taxes and junk but the latency is far too high for FPS.
With regard to your KVM box: Are you sure you connected the USB cables of the KVM box to 2 different USB host adapters
? One host adapter must be used by the dom0, the other one must be passed through to Windows. Another thing to watch out for is that you use USB 2 hosts for your keyboard/mouse. Don't try USB 3 host adapters - they may cause troubles in both Linux and Windows for mouse/keyboard. I had to install a 2 port USB panel and connect the cables to an appropriate USB header on my mother board. Why? Because the USB connectors on my motherboard (back and front panels) were all either USB 2 connected to one host, or USB 3 connected to another host. To get a second USB 2 host I had to add an USB panel on the back and connect it to an USB header on the motherboard (not any header, but the first one in my case). Check with an USB pendrive. You absolutely must have different host adapters for both dom0 and domU.
"For those of you not gaming (why are you using passthrough if you're not gaming?) Synergy is ****in' stellar."
1. I need to check out synergy.
2. Gaming is peanuts compared to photo editing. OK, I grant that gaming may be more demanding on the graphics card. BUT, if you want to edit photos and are serious about it, you need to calibrate your screen and - again, you are serious - your screen supports internal LUTs. In simple terms, you need to have Windows upload your screen calibration to the screen via DVI. That is the first requirement. The next one is to have Adobe Lightroom and Adobe Photoshop use the graphics card to speed up graphics processing. Believe me, RAW photo processing is VERY CPU and graphics card intensive. So, I'm not a gamer but I really need full access to the graphics card from within Windows (as well as access to the USB port to connect my colorimeter). Xen VGA passthrough works perfect for this, if you get it working.
