Those not starting with an underscore '_' are RandR 1.3 standard properties.
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) displays.
-
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 indicates 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:
-
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 x
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 controllable by the driver.
-
_Coherent
-
-
Type:
-
int32
-
Range/List:
-
0-1
Sets the coherent flag for TMDS signals. See also
Option
Coherent.
XVIDEO ATTRIBUTES
On R600 and above, the following XVideo attributes are supported.
Use
xvattr
to query and set these values at runtime.
-
XV_COLORSPACE
-
Select the Y'CbCr color space of the source video. Accepted values
are 'auto-detect'(0), 'Rec.601'(1), and 'Rec.709'(2).
Rec.709 is the standard which applies to high-definition television
broadcasting and "HD" digital video in general; Rec.601 applies to all
other digital video.
When 'auto-detect' is selected, Rec.709 is used for videos encoded
at least 928px wide, and Rec.601 is used otherwise.
This cut-off is lower than 720p so that the correct color space can be
applied to some media with non-standard resolutions that have high-probability
of having originated from Rec.709 encoded content.
Default is
'auto-detect'(0).
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.
