read-edid is a pair of tools (originally by John Fremlin) for reading the
EDID from a monitor.  It should work with most monitors made since 1996,
assuming the video card supports the standard read commands (most do).
Two tools are provided: get-edid, which gets the raw EDID information from
the monitor, and parse-edid, which turns the raw binary information into a
xorg.conf-compatible monitor section (or xrandr-compatible modelines).
Categories: sysutils
FreeBSD has mapping at zero address feature turned off since 8.0-RC2:
This is required to read EDID data via classical VBE interface (to avoid
"mmap /dev/mem: Invalid argument" message from libx86).  To temporarily
disable this protection, issue the following command:
# sysctl security.bsd.map_at_zero=1
To return to secure state:
# sysctl security.bsd.map_at_zero=0
