xcmddc(1) General Commands Manual xcmddc(1) NAME xcmddc - monitor EDID fetching over i2c SYNOPSIS xcmddc [ -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 communication 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 stdout. --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 Print a help text: xcmddc -h AUTHOR Kai-Uwe Behrmann (ku.b (at) gmx.de) COPYRIGHT (c) 2010, Kai-Uwe Behrmann License: MIT <http://www.opensource.org/licenses/mit-license.php> SEE ALSO xcmedid(1) xcmevents(1) libXcm(3) XcmDDC(3) http://www.oyranos.org REPORTING BUGS at: https://github.com/oyranos-cms/xcm/issues User Commands November 22, 2016 xcmddc(1)
