Hi, I''m currently working on stereoscopy on Xen unstable and Xen 4.1.3. With the latest catalyst driver and quadbuffer activated, I''m not able to have active stereo. I''ve run some tests; all software that I''ve found, runs in stereo modes. But for active stereo, there is no signal output for synchronization and there is only one image rendered. I''ve tested with others stereo modes without issues. Could it be something I''ve don''t set properly? Someone has been able to have active stereo with Xen 4.1.3? From a fresh install I''ve changed my grub.cfg for passtrough and set my DomU config file (for Xen 4.1.3): _________________________________ 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'' builder = ''hvm'' memory = 3072 shadow_memory = 8 name = "VM" vcpus=3 disk = [''file:/home/xen/domains/VM/first.img,ioemu:hda,w'',''phy:/dev/cdrom,hdc:cdrom,r''] device_model = ''/usr/'' + arch_libdir + ''/xen/bin/qemu-dm'' usb=1 keymap = ''fr'' boot = ''dc'' sdl = 0 vnc = 1 vncconsole = 1 vncpasswd = '''' gfx_passthru=1 pci=[''01:00.0'',''00:1a.0'',''00:1a.1'',''00:1a.2'',''00:1d.0'',''00:1d.1'',''00:1d.2'',''0f:00.0'',''0f:00.1''] _________________________________ 01:00.0 = network card 0f:00.0 = VGA card 0f:00.1 = HDMI audio device 00:1a.0 to 00:1d.2 = USB Computers: HP Z800 workstation ATI FirePro V8800 Intel Xeon E5640 Intel 5520 chipset Debian 6.0.5 Thanks, Aurelien _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
