Thank you, Allen for your replay.

I'll try to check this on other hardware.

As for Win7-64. It looks differently how IGD works. I mean when driver starts,  I could recognize the windows' greeting and login. But the point is that the display is not normal, not usual. It looks like the brightness is so low, that I could hardly recognize what is output on the screen.

Attached qemu's log for win7.

I noticed you are using WinXP guest.  Have you tried Win7-64 guest?  Do you have another Calpella laptop (i.e. Thinkpad T41) to try on?

It would be interesting to know if this problem is WinXP specific or HP 8440p specific.  I know there are there are quite a bit of difference between XP and Win7 IGD driver.

I have ready access to ThinkPad and Dell Calepella laptop.

Subject: [Xen-devel] IGD passthrough

Hello, everybody!

I've got an issue concerning IGD passthrough on calpella/sandybridge platform.
The IGD have passthrough-ed well on Win7 and WinXp until I setup native driver for GPU.

After installing drivers and rebooting domain the display got black when driver starts.

I found the similar issue

Could you provide any advice to make graphic works?

My system:
Hardware : EliteBook 8440p
Xen - xen-4.1.0-rc6
