Choose this option if you have a system that has "Intel Graphics

This driver is used by the Intel driver in X.org 6.8 and
|
||
|
|
XFree86 4.4 and above. It replaces the older i830 module that
|
||
|
|
supported a subset of the hardware in older X.org releases.
|
||
|
|
|
||
|
|
Note that the older i810/i815 chipsets require the use of the
|
||
|
|
i810 driver instead, and the Atom z5xx series has an entirely
|
||
|
|
different implementation.
|
||
|
|
|
||
|
|
If "M" is selected, the module will be called i915.

parameter. Using the module parameter overrides this option.

Force probe the driver for new Intel graphics devices that are

recommended to upgrade to a kernel version with proper support as soon

as it is available.

Use "" to disable force probe. If in doubt, use this.

Use "<pci-id>[,<pci-id>,...]" to force probe the driver for listed

devices. For example, "4500" or "4500,4571".

Use "*" to force probe the driver for all known devices.

Choose this option if you want to enable Intel GVT-g graphics

device shared by multiple VMs under different hypervisors.

Note that at least one hypervisor like Xen or KVM is required for

this driver to work, and it only supports newer device from

Broadwell+. For further information and setup guide, you can

you own risk.
