- Update to ddcutil 0.9.2
* Command ddcutil detect
+ Eliminate the Supports DDC: line. The output of this line reflects the result
of a simple test for slave address x37 at the I2C layer. This command can
fail on monitors that support DDC and succeed in monitors where DDC is
turned off. The result of the x37 test is still reported as part of the
--verbose output of detect.
+ Eliminate duplicate displays for DisplayPort connected monitors.
* Command ddcutil --help
+ Include command scs (Save Current Settings) in the output of ddcutil --help.
ddcutil scs executes a Save Current Settings operation, which is supported
by some but not all DDC capable displays. This command was implemented some
time ago, but was not described in the help output.
* Command ddcutil environment
+ When checking for group i2c membership, issue a special message if running
as root instead of the generic message that the current user is not a
member of group i2c.
* USB connected displays
+ Fix an invalid feature read of a USB connected display, observed when
getting the controller manufacturer but VCP feature code xC8 is unsupported.
+ When reading a USB report, regard errno EINVAL as an expected indication
that no value is found rather than an unexpected status code.
* Tracing
+ Fix the cause of a segfault when tracing a write-only DDC exchange
(i.e. setting a VCP value)
+ Disable debug messages regarding device id table initialization in the
environment command.
+ Eliminate double newlines in several error and trace messages
* Building ddcutil
+ libusb function libusb_set_debug() is deprecated in recent libusb versions,
