Hi Yongjie,

I have installed Fedora 19 x86_64 as a dom0 and compiled and installed 
Xen 4.4-unstable changeset 27305 and Linux kernel 3.10.5. Previously I 
was using Ubuntu 12.04.2 LTS as dom0.

Although I did not get error code 43 for Intel HD Graphics 4600 in 
device manager, I am still getting only 16 colors on the display. I 
really do not know where the problem lies. Device manager says "This 
device is working properly.", yet I am still getting only 16 colors on 
the display.

Could you share with me your /etc/grub.d/40_custom GRUB2 contents?

Thank you very much.
