NAME
radeonhd - AMD GPG (ATI) R5xx/R6xx/R7xx video driver
SYNOPSIS
Section "Device" Identifier "devname" Driver "radeonhd" ... EndSection
DESCRIPTION
radeonhd is an Xorg driver for AMD GPG (ATI) R5xx/R6xx/R7xx based video cards. At the time of this writing, radeonhd has the following limitations: o Support for hardware-based 2D acceleration and Xvideo needs more testing on R6xx and R7xx based cards. o No TV and Component connector support so far. o After using the fglrx driver, radeonhd might fail to work properly. This combination is not and probably will never be supported. A reboot fixes problems in most cases, sometimes a powercycle is necessary. Unloading the kernel module is typically not enough. A more up-to-date list can be found on the wiki page.

CONFIGURATION DETAILS
Please refer to xorg.conf(5) for general configuration details. This section only covers configuration options specific to this driver, for Section "Device". Some options may be deprecated and considered to be removed or replaced by better implementations soon. Option "AccelMethod" "none|default|shadowfb|xaa|exa" Use the indicated accleration method. none does not accelerate anything at all. Discouraged. shadowfb is a software-only acceleration technique. Does not work together with DRI at the moment. xaa is the older but stable hardware-based acceleration technique. exa is the newer but more experimental hardware-based acceleration technique. The default is depending on the chipset, driver version, and state of acceleration techniques and tries to give the best user experience. Rotation isn't supported for the AccelMethods "none" and "shadowfb". Option "DRI" Use this option to enable 3D and Xv acceleration using DRI. Currently, the default is on on R5xx and RS6xx chips, and off on all others. Option "OffscreenSize" "<integer>M|<integer>%" Specify the amount of framebuffer memory used for offscreen pixmaps, in megabytes or percent of avail- able memory. This amount of memory is not available for DRI. Certain hardware and software limits apply. The default is 10%. Option "ScaleType" "none|center|scale|scale_keep_aspect_ratio|default" Sets the scaling mode for laptop flat panels when used together with an external screen. The scaling engine is capable of scaling both up and down. none means to not scale at all, i.e. the image will be displayed in the top left corner of the panel if the resolution of the external display is lower than the panel resolution. center means not to scale but center the image on the panel i.e. apply a black frame around the image on the panel if the resolution of the external display is lower than the panel resolution. scale means to always scale to the resolution of the external display filling the entire panel. scale_keep_aspect_ratio scales the panel display but keeps the aspect ratio of the external display, which means if the external display has a different aspect ratio than the panel it black borders will be added to the top and bottom or left and right. default keeps the aspect ratio, but does not to scale otherwise. The default is to keep the aspect ratio. Option "NoRandr" Disable RandR 1.2 support. This turns the driver back to use standard modesetting behavior. The default is to enable RandR 1.2 support. Option "SWcursor" "boolean" Enable or disable the software cursor. The hardware cursor is inactive when the software cursor is enabled. The default is off. Option "ForceReduced" "boolean" Force the use of reduced blanking modes. Use this if your LCD monitor does not provide correct EDID data and you need a reduced blanking mode to drive a high resolution mode over a single link DVI con- nection. The default is off. Option "UnverifiedFeatures" "boolean" The radeonhd driver sometimes relies on unverified graphics card features. You can add Option "Unveri- fiedFeatures" "off" to disable those when you run into difficulties. Option "RROutputOrder" "list-of-outputs" RandR modesetting only. Several legacy application rely on the Xinerama extension to determine the primary screen. RandR returns the viewport displayed on the first attached output of the internal table as the first Xinerama screen. If your outputs are ordered in the wrong way, you can reorder them by adding their names (sep- arated by spaces or commas) to the list-of-outputs. Typically only the first (primary) output has to be listed, remaining outputs are added automatically. The default is none. Option "IgnoreConnector" "string" Standard (non-RandR) modesetting only. Connector to be ignored during non-RandR modesetting. The default is none. Option "UseConfiguredMonitor" "boolean" Standard (non-RandR) modesetting only. Use or ignore the monitor section in xorg.conf. In standard modesetting radeonhd ignores the EDID data if a monitor section is configured. This is different to what most drivers behave like and a common source of configuration problems. Thus the default is off (i.e. ignore). Option "NoAccel" Disable all hardware acceleration. The default is to enable hardware acceleration. NOTE: Use of this option is considered deprecated. The AccelMethod option is considered to be more flexible. Option "HPD" "auto|off|normal|swap" Change the use of the hot plug detection (HPD) pins. On R5xx the according connector tables are often broken and have to be worked around. Auto Select method depending on chipset and board Off Don't use HPD pins. Some connectors might not be able to detect connections at all Normal Use connector table information as-is Swap Swap HPD pin 1 and 2 in connector table NOTE: Use of this option is discouraged. Whenever this option is needed to detect connected monitors correctly, please report to the mailing list. The default is Auto. Option "ForceDPI" "integer" Force the use of the specified pixel density in Dots Per Inch. The default is to use the monitor sup- plied values. NOTE: Use of this option is discouraged. Monitors should return valid DPI values, and the Xserver should honour them correctly. Option "UseAtomBIOS" "boolean" Selects the mode setting path. The default is chipset dependent. NOTE: Use of this option is discouraged. The driver should select the right path. If this option is needed to get your card working correctly, please report to the mailing list. Option "Audio" "boolean" This option enables the audio hardware, which is responsible for delivering audio data to the different HDMI capable conntectors and used to communicate with the audio driver of the operation system. The default is off. Option "HDMI" "string" Possible values are "DVI-I_0", "DVI-I_1"..,"DVI-D_0","DVI-I_1",.., "all". This option enables HDMI- Audio and HDMI-Info packets on the specified connector. This is the only way enabling HDMI at the moment, since decoding E-EDID data to check if monitor supports HDMI is not implemented (yet). Option "Coherent" "string" There are two different ways to program the TMDS encoder in an output for best signal quality for the transmitter chip used inside a digital monitor. This option may be used to set the programming for each output individually. The string is a space separated list of <output_transmitter>=on|off. Possible values for <output_transmitter> are: TMDS_A, TMDS_B, UNIPHY_A, UNIPHY_B, AtomOutputTMDSA, AtomOutput- LVTMA, AtomOutputKldskpLvtma, AtomOutputUniphyA, AtomOutputUniphyB. The log file should be consulted on which ones to use. The line: Option "Coherent" "TMDS_A=off TMDS_B=on" will set coherent mode to off for TMDS A and to on for TMDS B. The default for all outputs is off. Option "TVMode" "tv-mode" The TV standard to use on the TV output. NTSC NTSCJ PAL PALM PALCN PALN PAL60 SECAM CV Composite Video NOTE: This option isn't implemented yet and has no effect.
RANDR OUTPUT PROPERTIES
The following properties can be queried with xrandr --prop and some of them can be set with xrandr --output <output> --set <property> <value> . Those not starting with an underscore '_' are RandR 1.3 standard proper- ties. See the RandR 1.3 protocol description for more details. Properties marked Read-Only are provided by the driver for informational purpose only, those marked Static won't change during runtime. SignalFormat Read-Only Type: string Range/List: unknown VGA TMDS LVDS DisplayPort Signal format / physical protocol format that is used for the specified output. ConnectorType Read-Only Static Type: string Range/List: unknown VGA DVI DVI-I DVI-A DVI-D HDMI Panel DisplayPort Connector type, as far as known to the driver. Panel describes laptop-internal (normally LVDS) dis- plays. ConnectorNumber Read-Only Static Type: int32 Range/List: 0- Outputs that route their signal to the same connector MUST have the same connector number. Outputs with the same connector number MUST route their signal to the same connector, except if it is 0, which indi- cates unknown connectivity. _OutputNumber Read-Only Static Type: int32 Range/List: 0- A card may route one internal output to several connectors. Connectors that are driven by the same output cannot be driven by different Crtcs and are thus only allowed to be used in clone mode. The driver SHOULD emit an error message and continue as gracefully as possible if using different Crtcs for the same internal output is requested. Internal outputs are numbered from 1, 0 indicates that output routing is unknown. _PanningArea Type: string Format: <width>x<height>[+<xoffset>+<yoffset>] Specifies the panning area in RandR mode per output. It actually is a Crtc-specific property, but RandR doesn't support that yet. As the xrandr application typically always resets the framebuffer size with every action, --fb <width>x<height> has to be added on every invocation, unless there is an additional output configured that is using this size as its resolution. This property cannot be changed when in a rotated mode. NOTE: Use of this option is considered deprecated. The driver supports RandR 1.3 panning, which is included in Xserver 1.6. It is considerable more flexible, and should support rotated pans. _Backlight Type: int32 Range/List: 0-255 Specifies the backlight intensity on laptop panels, if controlable by the driver. _Coherent Type: int32 Range/List: 0-1 Sets the coherent flag for TMDS signals. See also Option Coherent.
KNOWN BUGS
As the radeonhd driver is still in development, some non-obvious things might not work yet. A list of major known bugs is maintained on the wiki. Other places to check for known bugs and solutions are the bugtracker at https://bugs.freedesktop.org/query.cgi?product=xorg&component=Driver/radeonhd and the mailing list archives at http://lists.opensuse.org/radeonhd/ radeonhd development caused a few bugs in Xorg and a number of bugs in xrandr(1) to be discovered. If you are using xrandr(1) versions older than 2007-11-10, you should try updating xrandr(1). Alternatively, you can try to always specify different CRTCs for all monitors by explicitly selecting them with --crtc [0|1] on the xrandr(1) command line.
