The radeon manpage is out of date it seems with the current
driver. There are new driver options. Perhaps this is the cause
of people's problems - the docs not matching the driver.
Option "MonitorLayout" "string"
This option is used to overwrite the detected
monitor types.
This is only required when driver makes a false
detection. The
possible monitor types are:
NONE -- Not connected
CRT -- Analog CRT monitor
TMDS -- Desktop flat panel
LVDS -- Lapto flat panel
This option can be used in following format:
Option "MonitorLayout" "[type on primary], [type on
secondary]"
For example, Option "MonitorLayout" "CRT, TMDS"
Primary/Secondary head for dual-head cards:
(when only one port is used, it will be treated as
the primary
regardless)
Primary head:
DVI port on DVI+VGA cards
LCD output on laptops
Internal TMDS prot on DVI+DVI cards
Secondary head:
VGA port on DVI+VGA cards
VGA port on laptops
External TMDS port on DVI+DVI cards
The default value is undefined.
Option "CloneMode" "string"
Set the first mode for the secondary head. It can
be different
from the modes used for the primary head. If you
don't have this
line while clone is on, the modes specified for the
primary head
will be used for the secondary head.
For example, Option "CloneMode" "1024x768"
The default value is undefined.
I'll update the radeon manpage in future builds.
