       radeonhd - AMD GPG (ATI) R5xx/R6xx video driver


       Section "Device"

         Driver "radeonhd"


       radeonhd  is  an  Xorg  driver  for AMD GPG (ATI) R5xx/R6xx based video

       RADEONHD is still very much work in progress.

       At  the  time  of  this  writing,  radeonhd  has  the  following  major

       · NO support for 2D & 3D acceleration, no support for Xvideo.

       · No TV, Component, and HDMI connector support so far.

       · Suspend  &  Resume  is pretty much untested. Often it just works, but
         your milage may vary.

       · After using the fglrx driver, the display can get very  jittery  with
         radeonhd.   Also suspend & resume will probably fail.  A reboot fixes
         this problem 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.

       Please refer to xorg.conf(5) for general configuration  details.   This
       section only covers configuration options specific to this driver. Some
       options may be deprecated and considered to be removed or  replaced  by
       better implementations soon.

       Option "SWcursor" "boolean"
              Enable  or  disable  the software cursor. The hardware cursor is
              inactive when the software cursor is  enabled.  The  default  is

       Option "NoAccel"
              Disable  all  hardware  accleration.  The  default  is to enable
              hardware acceleration.
              Acceleration is not implemented yet, so this option  is  ignored
              for the moment.

       Option "ShadowFB" "boolean"
              Enable  or  disable  shadow  framebuffer  support.  This greatly
              improves the speed of unaccelerated drivers. The default  is  on
              as long as acceleration is not supported.

       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 "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 connection. The default is off.

       Option "HPD" "hpd-mode"
              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 "RRUseXF86Edid" "boolean"
              RandR modesetting only.
              Enable   or   disable   the   use   of  xf86OutputGetEDID()  and
              xf86OutputGetEDIDModes() instead of the  default  routines  from
              radeonhd,  which  are better adapted to the chipset. Panels will
              often fail to work with these calls. The default is off.

              NOTE: Use of this option is considered deprecated. Report to the
              mailing list if this is needed for your configuration.

       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 (separated
              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).


       The  following properties can be queried with xrandr --prop and some of
       them can be set with xrandr --output <output> --set <property>  <value>
       .   Those  marked  with  RR13  are  probably  merged  into  a RandR 1.3
       standard.  Properties marked Read-Only are provided by the  driver  for
       informational  purpose  only,  those  marked Static won’t change during

       RANDR_SIGNAL_FORMAT   Read-Only RR13

              Type:           string
              Range/List:     unknown VGA TMDS LVDS  FBAS  FBAS-PAL  FBAS-NTSC
                              FBAS-SECAM SVideo YPbPr DisplayPort

              Signal  format  /  physical protocol format that is used for the
              specified output.
              A driver MAY change this property of an output if the underlying
              hardware  indicates a protocol change (e.g. TV formats).  Values
              with dashes (FBAS-PAL) describe more specific  versions  of  the
              base values (FBAS) and SHOULD be used if known to the driver.

       RANDR_CONNECTOR_TYPE   Read-Only Static RR13

              Type:           string
              Range/List:     unknown  VGA DVI DVI-I DVI-A DVI-D HDMI PANEL TV
                              TV-FBAS  TV-SVideo   TV-YPbPr   TV-SCART   TV-C4

              Connector type, as far as known to the driver.
              Values  with dashes (TV-FBAS) describe more specific versions of
              the base  values  (TV).   The  former  SHOULD  be  used  if  the
              connector  is not capable of producing other signal formats. The
              later SHOULD be used if the exact connector is unknown,  or  the
              connector  is  a  multi-format  connector  that is not described
              otherwise.  DVI, for instance, SHOULD be handled  like  a  DVI-I
              connector,  unless  additional  information  is available to the
              user agent.  PANEL  describes  laptop-internal  (normally  LVDS)
              displays.   TV, TV-SCART, TV-YPbPr, and TV-C4 with signal format
              VGA are valid combinations and describe RGB TV signals.

       RANDR_CONNECTOR_NUMBER   Read-Only Static RR13

              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 indicates unknown connectivity. 1 is called the
              primary connector, 2 the secondary. 3 is often a  TV  connector,
              but that is completely driver / hardware dependent.
              Outputs  with  the  same  connector  number SHOULD have the same
              connector type.  Meaning and  client  behavior  for  mismatching
              connector types is undefined at the moment.

       RANDR_OUTPUT_NUMBER   Read-Only Static RR13

              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.


              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.


       As the radeonhd driver is still in an early stage of development,  many
       non-obvious  things  do  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
       and the mailing list archives at

       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.
