I don't think this is a duplicate of #22328.
First of all the bug descriptions are different:
* #22328 - says the display will be blank with resolutions 1280x800, 1024x768 and 800x600, but it can display normal when changed to 640x480
* this bug says that everything works fine with those resolutions, but stops working when using the Virtual line in xorg.conf.

I built the xserver containing the changes that fixed #22328
    non-DRI FB resize failed to assign the screen pixmap devPrivate.ptr (22328)
but it still does not fix my problem (and as you can read from the Launchpad bug it does not fix it for other either https://bugs.edge.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/383345).

* without "Virtual" in xorg.conf everything seems to work fine (no change from before - two screens can be mirrored)
* with "Virtual" in xorg.conf I tested two cases:
** Virtual 2960 1065 -- gdm would not start, and it seamed stuck in a loop trying to start the x server
** Virtual 2048 1065 -- gdm would start, but the image on the screen was destroyed (thin lines from the images dispersed over the screen), BUT the mouse pointer was displayed correctly.
