`devg-intelhd.so`

Graphics driver for Intel GMA HD graphics

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.

Description:

The devg-intelhd.so driver provides accelerated 2D support for Intel Graphics Media Accelerator (GMA) High Definition (HD) chips.

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.
