- update to 1.2.1:
* User Defined Features, which have existed for some time, are now formally
available.
* Option --mccs now applies to getvcp, setvcp, and dumpvcp as well as vcpinfo.
* Workaround for EDID reading issu with recent kernels and i915/docking stations
* Configuration file ddcutilrc, located on the XDG config path (normally
$HOME/.config/ddcutil/ddcutilrc) is processed by both ddcutil and
libddcutil.
* Monitor capabilities strings are cached to improve performance of the
capabilities command.
* Partial workarounds for problems in DRM video drivers (e.g. i915, AMDGPU)
when monitors are connected to a docking station. The monitor may not be
detected (because no EDID is reported), or the monitor may appear as two
different /dev/i2c devices.
* When probing /dev/i2c devices for monitors, ddcutil could put AMD Navi2
devices (e.g. RX6000 series) into an inconsistent state. This is because
the devices expose an I2C devices for the SMU. Display detection is
modified to avoid probing these devices.
* Option -enable-capabilities-cache is now the default.
* Command ddcutil --verbose reports the raw EDID.
* Major events are written to the system log. These include starting,
stopping, and severe internal errors.
* Fix for github issue #178: Error detecting i2c-dev kernel module. The
checks are now performed using libkmod.
* libddcutil trace output can be redirected to a file.
* The shared library file name is libddcutil.so.4.1.0
