NVIDIA LINUX LAPTOP DOCUMENTATION


        -----


Preliminary support for laptops equipped with GeForce2 Go GPUs is now
included with the NVIDIA Accelerated Linux Driver Set.


        -----


INSTALLATION AND CONFIGURATION

Installation and configuration is the same as for any desktop environment,
with the exception that the option "NVreg_Mobile" MUST be passed to
the NVdriver kernel module.  This can be done either using the modprobe
command:

        modprobe NVdriver NVreg_Mobile=X

or by adding the following to your kernel module configuration file
(usually either /etc/conf.modules or /etc/modules.conf):

        options NVdriver NVreg_Mobile=X

However you specify the option, you should assign it the value:

        "1" if you are using a GeForce2 Go in a Dell laptop
        "2" if you are using a GeForce2 Go in a Toshiba laptop

For example, if you are using a Toshiba Satellite laptop with
GeForce2 Go, you would add:

        options NVdriver NVreg_Mobile=2

to your kernel module configuration file.

If no option is specified, the NVIDIA X driver will fail to initialize
the NVdriver kernel module, and X will fail to start.

KNOWN ISSUES

As this is only preliminary support, there are several issues with the
current drivers that will be addressed in a future release:

o Most notably, a system hang may occur when running X a second time;
  the only workaround is to reboot after exiting X before starting
  X again.

o Additionally, hotkey switching between the CRT and LCD while X is
  running is not yet supported.

o There also appear to be some issues with restoring the vga console
  when X is run on a display different than what the system booted on.
  For example, booting the system on the internal LCD, but instructing
  X to display on an external CRT (this is the default when X runs with
  TwinView not enabled but detects that both an external CRT and the
  internal LCD are connected).  It is recommended to hotkey switch at
  the vga console to the display on which X will be run before starting X.

o Finally, power management is not yet supported.
