RADEONHD(4)                Kernel Interfaces Manual                RADEONHD(4)

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

       Section "Device"
         Identifier "devname"
         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  limita-

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

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

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

       o 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.

       The  radeonhd  driver  supports  video cards based on the following ATI

       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 "AccelMethod" "none|default|shadowfb|xaa|exa"
              Use  the  indicated accleration method. The default is depending
              on chipset version and  state  of  acceleration  techniques  and
              tries to give the best user experience.  shadowfb is a software-
              only acceleration technique, while xaa  and  exa  are  hardware-
              based acceleration techniques.

       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 "OffscreenSize" "<integer>M|<integer>%"
              Specify  the  amount  of  framebuffer  memory used for offscreen
              pixmaps, in megabytes  or  percent  of  available  memory.  This
              amount  of memory is not available for DRI. Certain hardware and
              software limits apply. The default is 10%.

       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 dis-
              played 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).

       Option "NoAccel"
              Disable all hardware acceleration.  The  default  is  to  enable
              hardware acceleration.
              NOTE:  Use  of  this option is considered deprecated. The Accel-
              Method option is considered to be more flexible.

       Option "ShadowFB" "boolean"
              Enable or  disable  shadow  framebuffer  support.  This  greatly
              improves the speed of unaccelerated drivers. The default depends
              on chipset and acceleration state.
              NOTE: Use of this option is considered  deprecated.  The  Accel-
              Method option is considered to be more flexible.

       Option "RRUseXF86Edid" "boolean"
              RandR modesetting only.
              Enable or disable the use of xf86OutputGetEDID() and xf86Output-
              GetEDIDModes() 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.

       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 stan-
       dard.  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  Dis-

              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  connec-
              tor  is not capable of producing other signal formats. The later
              SHOULD be used if the exact connector is unknown, or the connec-
              tor 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 num-
              ber MUST route their signal to the same connector, except if  it
              is 0, which indicates unknown connectivity. 1 is called the pri-
              mary 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 con-
              nector type.  Meaning and client behavior for  mismatching  con-
              nector 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 sup-
              port 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 main-
       tained on the wiki.  Other places to check for known bugs and solutions
       are the bugtracker at
       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.
