| Version: 1.4.1 | Vendor: openSUSE |
| Release: 2.1 | Build date: Wed May 10 19:44:51 2023 |
| Group: System/GUI/Other | Build host: old-cirrus1 |
| Size: 1017589 | Source RPM: ddcutil-1.4.1-2.1.src.rpm |
| Packager: https://bugs.opensuse.org | |

| Summary: Utility to query and update monitor settings | |
ddcutil communicates with monitors implementing MCCS (Monitor Control Command Set), using either the DDC/CI protocol on the I2C bus or as a Human Interface Device on USB. A particular use case for ddcutil is as part of color profile management. Monitor calibration is relative to the monitor color settings currently in effect, e.g. red gain. ddcutil allows color related settings to be saved at the time a monitor is calibrated, and then restored when the calibration is applied.
GPL-2.0-or-later
* Sun Apr 23 2023 Stefan Brüns <stefan.bruens@rwth-aachen.de>
- Split udev rules from command line tools (main) package. Allows
distribution wide usage of libddcutil without affecting device
permissions and security.
* Sat Jan 28 2023 Dirk Müller <dmueller@suse.com>
- update to 1.4.1:
* The default sleep-multipler value was 0, instead of 1. This resulted in
failure of most DDC/CI operations, including display detection.
* Mon Jan 16 2023 Paolo Stivanin <info@paolostivanin.com>
- Update to version 1.4.0:
+ The ability to use the write()/read() interface of i2c-dev has been restored.
It is needed to work around a bug in the proprietary nvidia driver. By
default, the write()/read() interface is used for the nvidia driver, the
ioctl() interface is used for all other drivers. Command line options
* **--use-file-io*** and ***--use-ioctl-io*** affect his default behavior.
When i2c-dev's file io interface is used, option ***--force-slave-address***
is again meaningful.
+ Option ***--sleep-multiplier*** and API functions **ddca_set_sleep_multiplier_value()**,
* *ddca_set_default_sleep_multiplier_value()** now accept 0 as a valid
argument.
+ The ddcutil command parser reports an error if a display selection option
(e.g. ***--bus***) is given on a command to which it does not apply.
+ Write additional error and information messages to the system log.
+ Eliminate message "Is DDC/CI enabled in the monitor's on-screen display?"
It's rarely the cause of communication failures.
+ Warn of a possibly invalid DRM connector name in **detect** output if
monitors with identical EDIDs are used with the proprietary nvidia driver.
+ Handle /dev/i2c device names with a double hyphen, e.g. /dev/i2c--3.
+ Better libddcutil handling of configuration file errors. Do not abort
initialization in case of errors.
+ Fix interpretation of digital display type bits for EDID version 1.4
+ Miscellaneous segfaults.
* Tue Nov 08 2022 Andrea Manzini <andrea.manzini@suse.com>
- Update to version 1.3.0:
+ Option --force-slave-address no longer has any effect
+ Commands getvcp and vcpinfo can now take multiple features as arguments, for example ddcutil getvcp 10 12
+ Better reporting of user configuration issues at startup.
+ The sleep-suppression related options, --sleep-less, --less-sleep,
- -enable-sleep-suppression, and --disable-sleep-suppression no longer have any effect
* Thu May 19 2022 Dominique Leuenberger <dimstar@opensuse.org>
- Update to version 1.2.2:
+ Improve handling of and messages regarding DDC communication
failures with errno EBUSY. In particular, this error occurs
when driver ddcci is loaded.
+ Command **detect**: If DDC communication fails with error
EBUSY, report the display as "Busy" instead of "Invalid" and
suggest use of option ***--force-slave-address***.
+ Command **environment**: Suggest use of option
* **--force-slave-address*** if driver ddcci is detected.
+ Messages re EBUSY errors are always written to the system log.
+ Command **detect**:
- Do not report the EDID source unless there is a value to
show. This value is set only for USB connected monitors.
- Show extended output based on option ***--verbose***, not
undocumented option ***--very-verbose***.
- Report color bit depth if EDID version >= 1.4
+ Command **environment**: Simplify the exploration of sysfs.
+ API changes:
- Field latest_sl_values in struct DDCA_Feature_Metadata struct
is no longer set,
- API function ddca_report_display_info(): include binary
serial number.
+ Building and porting:
- When building ddcutil, allow for building a static library if
* *configure** option ***--enable-static*** is set. Linux
distributions frown on packaging static libraries, but if a
user wants to build it who am I to judge. By default, static
libraries are not built.
- Replace use of Linux specific function **__assert_fail()**
with **exit()** in traced assertions. **__assert_fail** is
used in the Linux implementation of **assert()**, but is not
in the C specification. This can present a problem in
porting ddcutil.
+ Code cleanup:
- Delete incomplete, experimental code for asynhronous feature
access, including files src/ddc/ddc_async.c/h.
- Remove unused files src/util/output_sink.c/h.
+ Fixed
- Only write Starting/Terminating messages to the system log if
option ***--syslog*** is specified.
- Avoid compilation warnings when assert() statments are
disabled (NDEBUG is defined).
- Fixed a segfault in the debug/trace code of
ddca_get_display_refs().
* Mon Apr 25 2022 Dominique Leuenberger <dimstar@opensuse.org>
- Rename libddcutil3 subpackage to libddcutil4, making the package
name actually match the provided library. conflict the wrongly
named package.
* Mon Dec 20 2021 Dirk Müller <dmueller@suse.com>
- 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
* Thu Jul 01 2021 Steve Kowalik <steven.kowalik@suse.com>
- Remove unncessary BuildRequires on python-devel
* Sun Aug 16 2020 Dirk Mueller <dmueller@suse.com>
- update to 0.9.9:
* Additional per-thread statistics are shown when --verbose is specified along with --stats
* --dynamic-sleep-adjustment
* ddcutil no longer supports AMD's old proprietary display driver fglrx
* Mon May 25 2020 Simon Lees <simonf.lees@suse.com>
- Update to ddcutil 0.9.8
* A new command line option, --sleep-multiplier, adjusts the time ddcutil
pauses between sending a request to the monitor and reading from the
monitor.
Many monitors work successfully with shorter sleep durations than required
by the DDC/CI specification, in which case ddcutil execution time can be
considerably reduced. On the other hand, some monitors having communication
difficulty may work with longer sleep durations than required by the DDC/CI
specification.
* A bug fix for the situation where certain mice would lock up during
display detection.
* libddcutil api break and move to v2
* The libddcutil shared library API has some minor extensions.
- cmake files installed to right location
- Update to ddcutil 0.9.7
* Fixed the cause of a segfault during display detection if a monitor
appearing to support the USB Monitor Control Class Specification, i.e. one
that uses USB to communicate monitor settings, is connected to the system.
* The release also contains some minor code cleanup.
- Update to ddcutil 0.9.6
* SONAME support is enabled for libddcutil.
* Other minor enhancements, bug fixes, and API changes.
* Tue Feb 26 2019 Antonio Larrosa <alarrosa@suse.com>
- 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/)
- Update to ddcutil 0.9.4
* Fix the cause of failure to build from source for the x32 ABI. The file
output by the dumpvcp command no longer contains a TIMESTAMP_MILLIS field,
the number of seconds since start of the machine epoch, typically
January 1, 1970. This field, and its companion TIMESTAMP_TEXT, are ignored
on input, so this change can only affect an external program that relies
on the TIMESTAMP_MILLIS field, say for sorting.
* Fix an execution failure that resulted from attempting to open an already
opened display. This occured on the capabilities command when the vcp
field in the string returned by the monitor was damaaged or missing,
causing ddcutil to attempt to read the VCP version from feature 0xDF.
* Features 0x59..0x5E (6 axis separation values). Report these values as
normal continuous (C) values instead of just uninterpreted bytes.
- Update to ddcutil 0.9.3
* Display Detection
Display detection no longer performs initial probes of I2C slave addresses
on each possible /dev/i2c device. These initial probes do not return valid
information on a Dell P2715Q, and have been seen to cause screen corruption
on Dell XPS 13 laptops. In addition, /dev/i2c devices for Synopsys
DesignWare are automatically skipped.
As a result of the changes to display detection, ddcutil detect --verbose
no longer reports the presence of slave addresses x30 (EDID block number)
or x37 (DDC), but does report whether a display is an Embedded Display
Port (eDP) device, which is the case for recent laptop displays. It also
reports the sysfs device name.
* User Supplied Feature Definitions
ddcutil internals have been extensively restructured for future support of
user supplied feature definitions. This will allow users to supply feature
definitions for manufacturer reserved features, i.e. those in the range
xe0..xff. While not yet ready for public use, there are a couple changes
already visible in the user interface
* Tracing
Added trace groups: UDF (user defined features), DDCIO (low level DDC
functions), VCP (feature metadata).
Because of the volume of output, trace group "DDC" has been split into DDC
and DDCIO, with the latter containing low level DDC services.
* API Changes
The C API has had a few changes to support user supplied feature
definitions and reflecting experience gained from work on the Qt C++ GUI
interface. See API Changes in Release 9.3
(https://www.ddcutil.com/c_api_93/) for details.
* Miscellaneous
Vebose output of the environment command now displays execution timestamps
to aid in interpreting system logs.
