[Qemu-devel] xp guest display settings

[Ronald]

Hi,

I have done two install of XP in the last 24h, one on linux and the other
on xp, the two are ok.
I write here about some display problem when running xp on qemu on linux
host, I have not tried on xp host.
When using 16bits display settings (in guest) the display is somewhat
bad (still speaking of guest), whereas in 24bits it's fine. I've tried
with different resolution/refresh in 16bit but still get the same result.
I have not seen such a problem with other guests. On host side X is
running at 1024x768x16, qemu -latest cvs- is launched with -m 128
-localtime -user-net -enable-audio.

I've already seen this on xp host. The trick is to turn off the qemu
instance, launch another vm, then go back to the 16 bits qemu instance
which had problems. And it should be ok then.

It seems changing depth of color map to 16bits in SDL does garbage the
SDL content. I think this is not from Qemu, but inside SDL itself.

Thanks, shutting down xp after changing setttings did the trick, this
didn't work with a simple reboot. I don't even need to launch another qemu
session between the two xp boot.
