will not claim
Specific to the device you wish to prevent from claiming.
This tunable specifies the PCI Vendor ID and/or Device ID of a graphics
device that the HP graphics driver should not claim.
The graphics driver was designed to be a general purpose driver for all
PCI graphics cards. As a result, the driver will attempt to claim any
PCI graphics display device found on the system. This can be a problem
for graphics device developers who need their own graphics driver to
claim their own graphics device.
The value of will specify a PCI Vendor ID and/or Device ID of a graph‐
ics card that the gvid graphics driver should not claim. It is a 32
bit number, with the upper 16 bits containing the PCI Vendor ID and the
lower 16 bits containing the PCI Device ID. Either the Vendor ID or
Device ID can use a wildcard value of
For example, if is set to the value the driver will ignore graphics
devices with a PCI Vendor ID of and a Device ID of If is set to the
driver will not claim any graphics cards with a Vendor ID of regardless
of the Device ID.
Who Is Expected to Change This Tunable?
Anyone who wishes the graphics driver to ignore a specific graphics
device. This will typically be someone writing their own graphics
driver for their own hardware.
Restrictions on Changing
Changes to this tunable take effect at the next reboot.

Installation of optional kernel software, from HP or other vendors, may
cause changes to tunable parameter values. After installation, some
tunable parameters may no longer be at the default or recommended val‐
ues. For information about the effects of installation on tunable val‐
ues, consult the documentation for the kernel software being installed.
