SYNOPSISxcmddc [ -l [-v] ]
xcmddc [ -d POSITIONAL_NUMBER [--force-output] [--identify] ]
xcmddc [ --i2c NODE_NAME [--force-output] [--identify] ]
xcmddc [-h]
DESCRIPTION
The xcmddc tool fetches a monitors EDID data block over a i2c communi‐
cation channel.
OPTIONS-l list devices. Only devices which provide a EDID data block and
the EDID's header is valid will be counted.
-v show each device by its node name.
-d=POSITIONAL_NUMBER , -d POSITIONAL_NUMBER
position in device list. The numbering of monitors starts with
zero for the first device. To get the number of all available
devices use "xcmddc -l". The EDID data block is dumped to std‐
out.
--force-output switch EDID header verificatcationn off.
--identify dump the error code as integer to stdout.
--i2c=NODE_NAME , --i2c NODE_NAME
select the i2c device node file. The EDID data block is dumped
to stdout. The --i2c option is much faster than the -d option.
This is because of much fewer timeouts reuired for counting the
valid i2c device with the -d option.
--force-output switch EDID header verification off.
--identify dump the error code as integer to stdout.
GENERAL OPTIONS-v, --verbose
increase verbosity
EXAMPLES
Count available i2c->monitor devices:
xcmddc-l
List available i2c->monitor devices by name:
xcmddc-lv
Dump EDID from first i2c node:
xcmddc-d 0
Dump EDID by i2c device name:
xcmddc--i2c /dev/i2c-5
