`devg-poulsbo.so`

Graphics driver for Intel Poulsbo chipsets

Syntax:

io-display [-vf]
           -d vid=[0x]vendor_id,did=[0x]device_id[,deviceindex=index]
           [-c config_file] [-p priority]

Options:

For the general io-display options that you can use with this driver, see io-display.

You can set configuration options that are specific to this driver by using the modeopts setting in display.conf:

modeopts=config-file: The full path to the configuration file for the driver. For example, poulsbo.conf is located in /usr/photon/config so that modeopts=/usr/photon/config/poulsbo.conf.

Description:

The devg-poulsbo.so driver provides accelerated 2D and 3D support. You can edit the configuration file to enable devg-poulsbo.so to run on your board.

Graphics drivers run at a higher priority than applications, but they shouldn't run at a higher priority than the audio, or else breaks in the audio occur. You can use the on command to adjust the priorities of the audio and graphics drivers.
