Hello, I would like to get dual head working with my xen installation -- I have two monitors, and my video card supports it (works flawlessly with nvidia driver on vanilla kernel). I have an NVidia 9500GT. [root@localhost ~]# cat /etc/redhat-release Scientific Linux SL release 5.3 (Boron) [root@localhost ~]# uname -rmsrv Linux 2.6.18-128.7.1.el5 #1 SMP Mon Aug 24 08:12:52 EDT 2009 x86_64 [root@localhost ~]# lspci | grep VGA 01:00.0 VGA compatible controller: nVidia Corporation GeForce 9500 GT (rev a1) I managed to get through the installation just fine, but when I restart gdm, (gdm-restart) I get no output from the video card and the computer is unresponsive - almost as if it crashes. I have to restart the computer to get it working. I've tried to follow these instructions here: http://kbase.redhat.com/faq/docs/DOC-9724 Thanks, -Chris Tooley
