X-server problem using sdl with nvidia graphics

X-server problem using sdl with nvidia graphics

[Juergen Gross]

Hi,

I'm playing a little bit with Windows domU on Xen. My machine is a Notebook
with a nvidia card:

01:00.0 VGA compatible controller: nVidia Corporation G96M [Quadro FX 770M] 
(rev a1)

Xen is Xen 4.0.1 from SLES 11 SP1, Xserver is xorg 7.4-27.19.19.
When I use vnc as console for the domU, everything is okay. Using sdl will
blank my screen as soon as the domain is started and the sdl window should
appear. I can get the X screen again via switching to text console and back,
but the sdl window isn't there.
Starting the domain with sdl using an external DISPLAY works okay.

Has anybody seen this problem?
Any ideas how to solve it?

I tried with nv driver from SLES and nvidia driver from nvidia.com. Both
failed.

Guest configuration:

import os, re
arch = os.uname()[4]
if re.search('64', arch):
     arch_libdir = 'lib64'
else:
     arch_libdir = 'lib'
kernel = "/usr/lib/xen/boot/hvmloader"
device_model = '/usr/lib' + '/xen/bin/qemu-dm'
builder='hvm'
memory = 4096
shadow_memory = 32
name = "Win"
vif = [ 'type=ioemu, bridge=extbr1', 'type=ioemu, bridge=intbr1' ]
disk = [ 'phy:/dev/sda,ioemu:hda,w' ]
boot="c"
vcpus=1
acpi=1
apic=1
sdl=1
vnc=0
vncconsole=0
vncviewer=0
vncpasswd=''
vnclisten="0.0.0.0"
stdvga=0

Hi,

sorry for late reply, I was at home for 1 week :-)

Doesn't help.

Considering that it looks like an xorg issue or a dom0 kernel issue,
could you try executing any other sdl based programs?
For example 'mplayer -vo sdl <your video>'?
If you can repro the issue with another application we can rule out that
is a qemu-xen bug.

The "Color Mouse Demo" from http://www.libsdl.org/projects/cmouse/ works
fine.
