RE: [Xen-devel] VMX status report. Xen: #17270 & Xen0: #488 -- no newissue

["Xu, Dongxiao" <dongxiao.xu@xxxxxxxxx>]

Hi, Stefano and Keir,

When I set sdl=1, vnc=0 and use VNC viewer to connect a host, then boot a 
windows guest, the color is abnormal.
    If I set sdl=0, vnc=1 and use VNC viewewr to connect a host, then boot a 
windows guest, the color is correct.
    If I use Domain0's X window to boot a windows guest and whatever sdl=1, 
vnc=0 or sdl=0, vnc=1, the color is correct.

    The color depth and resolution of my windows guest is: 800*600, 24bit or 
16bit. And my VNC version is: VNC Viewer Free Edision 4.1.1. I will check my 
Domain0's resolution and color depth when I back to company on Monday.

Best regards,
-- Dongxiao

Sorry I don't fully understand: is when you where using sdl=1 and vnc=0
(that is the SDL windows) that you saw abnormal colours or when you
where using sdl=0 and vnc=1 (vnc interface)?

These informations would be helpful:

- the colour depth and resolution in the window guest

- the colour depth and resolution  of your dom0 X window system

- which vnc viewer you are using (if the problem is with vnc)

Regards,

Stefano Stabellini

P.S.
I was independently able to reproduce another colour problem that
happens only when the guest colour resolution is 8 bpp.
