omap - OMAP SoC graphics


Section "Device"
  Identifier "devname"
  Driver "omap"


omap is an Xorg driver for OMAP SoCs.


omap supports the OMAP3430, OMAP3630, OMAP4430, OMAP4460


Please refer to xorg.conf(5) for general configuration details. This section only covers configuration details specific to this driver.
The following driver Options are supported
Option "Debug" "boolean"
Enable debug logging.
Default: Disabled
Option "DRI" "boolean"
Enable DRI2.
Default: Enabled
Option "NoAccel" "boolean"
Disable hw acceleration.
Default: Disabled
Option "HWcursor" "boolean"
Enable HW mouse cursor.
Default: Enabled


The driver supports runtime configuration of detected outputs. You can use the xrandr tool to control outputs on the command line as follows:
xrandr --output output --set property value
Note that you may need to quote property and value arguments that contain spaces. Each output listed below may have one or more properties associated with it (like a binary EDID block if one is found). Some outputs have unique properties which are described below. See the "MULTIHEAD CONFIGURATIONS" section below for additional information.
See xorg.conf(5) for information on associating Monitor sections with these outputs for configuration. Associating Monitor sections with each output can be helpful if you need to ignore a specific output, for example, or statically configure an extended desktop monitor layout.


The number of independent outputs is dictated by the number of CRTCs (in X parlance) a given chip supports. OMAP3xxx supports up to two, while OMAP4xxx supports up to three displays. The actual number of displays supported will depend on the board. But a built-in LCD and external HDMI are a common configuration.
You can use the "xrandr" tool, or various desktop utilities, to change your output configuration at runtime. To statically configure your outputs, you can use the "Monitor-<type>" options along with additional monitor sections in your xorg.conf to create your screen topology. The example below puts the VGA output to the right of the builtin laptop screen, both running at 1024x768.

The xf86-video-omap driver is part of the X.Org and umbrella projects. Report bugs at Mailing lists are also commonly used to report experiences and ask questions about configuration and other topics. See for more information (the mailing list is the most appropriate place to ask X.Org and driver related questions).
