When installing Nevada build 107 on one of my x86 systems with 2 graphics cards,
X Server will not start after the installation is complete and the system has
rebooted. dtlogin will not come up. I've attached the Xorg.log.0. Here is
the output from /var/dt/Xerrors:

From Alan Coopersmith:
"one of the bugs we inherited from the open source release is that systems
with multiple graphics cards need manual configuration to start Xorg now."
The upstream bug report is: https://bugs.freedesktop.org/show_bug.cgi?id=18321
Bug 18321: xserver 1.5.2 fails to start with more than one display card
Reproducible on OpenSolaris_117 X64 notebook Sony Z29N (one Intel graphic card, one Nvidia graphic card).
if I switch the graphics under Windows XP, Windows can properly use the right one and the other one is not visible to Windows after system reboot. The BIOS must disable the invisible one in the device initilization. However, if I switch the graphics under Solaris, both of the two graphics devices are visable to Solaris after reboot and Xorg can't start confused by two primary card. It is verly likely that Windows get some higher level driver to manage graphics chip switch that will affect the device initialization in BIOS. We must have platform specification to implement such a driver. With the driver, only the right graphics device will be visible to Solaris avoiding two visible primary cards.
Sony Z series user group get some ACPI hack for the cold switch. Here is the link,

or laptops like the Sony Vaio Z series, there is currently Linux support for cold switch of the graphics card:
Load Eva's sony-laptop module with speed_stamina=3.
In the file called /etc/modprobe.d/sony-laptop.conf add the following line:
-------------------------------------------------------------------
options sony-laptop speed_stamina=3
-------------------------------------------------------------------
Then boot with this kernel parameter (use the quotes):
-------------------------------------------------------------------
acpi_osi="!Windows 2006"
-------------------------------------------------------------------
Just put it in the kernel command line of your boot manager.
