- Update to ddcutil 0.9.5
* Feature x72 (Gamma)
Added support for Virtual Control Panel feature x72 (Gamma). This is
an unusual complex non-continuous feature in that its value can be
changed by the user, and the parenthesized "values" in the
capabilities string require special interpretation. The following
commands have been modified:
- ddcutil getvcp 72: Interpret the output
- ddcutil capabilities: Interpret the parenthesized "values" substring
- ddcutil setvcp: See below.
* Command setvcp
Can now take 2 byte values an an argument. Values can be specified as
hexadecimal (SH byte then SL) or as decimal (0..65535).
* Configuration and Diagnostics
Contrary to existing documentation, kernel module i2c_dev is in fact
required when using the proprietary Nvidia driver.
Kernel module documentation has been corrected, and command ddcutil
environment has been updated.
* Bug Fixes
Fix the cause of an assert failure when displaying the value of feature
x8F (Audio Treble) or x91 (Audio Bass).
* Monitor Quirks
Instead of setting the "unsupported feature" bit in the getvcp reply
packet for an unsupported feature, the Dell AW3418DW causes I2C failure
with Linux errno EIO. ddcutil now interprets the EIO response as
indicating an unsupported feature instead of reporting an error. This
special handling currently applies only to the Dell AW3418DW.
* Miscellaneous
Update file README.md and make it more usable as the github overview file.
* API Changes (see https://www.ddcutil.com/c_api_95/)
