- Require libddcutil from ddcutil 2.1.3 or later
- Ensure display status change detection is enabled for display connection and disconnection, not for DPMS asleep.
- When libddcutil detects connection or disconnection of a display, ddcui puts up a dialog box reporting the change and indicating that the user needs to redetect displays using Action->Redetect Displays.
- Options --enable-watch-displays, --disable-watch-displays By default ddcui watches for display connection events.
- If multiple "options" lines are found in a segment of configuration file ddcuirc, their contents are combined into a single value.
- Requires libddcutil.so.5.1 or later
- If CMakeLists.txt option ASAN is specified, cmake compiles ddcui using options required for ASAN and links the executable with libasan.
- Option --disable-syslog. Normally ddcui and libddcutil write important messages to the system log. This option disables that behavior.
- Option --libopts "". Passes an option string to the shared library. This string is appended to the option string obtained from configuration file $HOME/.config/ddcutil/ddcutilrc.
- Menu item Actions->Debug Locks reports locking the libddcutil as a debugging aid.
- CMakeLists.txt recognizes option DDCUTIL_PROJECT_DIR, which specifies the ddcutil project directory in which libddcutil is built. Using this option avoids having to install libddcutil.so in a system directory in order for ddcui to use it.
- Incremented required libddcutil version to 1.5.0
- ddcui options that exist solely to control libddcutil behavior. These include --ddc and --excp, --trace, --trcfunc, and --trcfile. These can now be passed as text strings using ddcui option --libopts.
- CTL-Q terminates ddcui (does not apply within dialog boxes)
- Errors opening /dev/i2c and /dev/usb/hiddev devices are reporting using a message box instead of to the terminal. These are typically lack of permissions (Linux error EACCESS).
- Optionally requiring the control key to be pressed when changing feature values now applies
to all changes, not just those made using sliders. (The option is set using command line
option --require-control-key or the UI Options dialog box).
- A status message is issued when the control key is required.
- Special handling for feature X60:
- Allow extra sleep time before validation. (It was observed that a Dell U4320 returns a Null Message if getvcap for validation is called too quickly
- For simple NC values, do not include the SH field in validation. (getvcp for feature x60 on Dell U4320 returns non-zero SH.)
- Options --force-slave-address and --disable-force-slave-address have no effect and are deprecated.
- Option dialogs: Tab key was not jumping to the OK and Cancel buttons
- Fix free() before final use in certain cases of function tracing.
- Custom feature lists: Fix assert statements.
- Memory leaks
- Cast many pointers to ( void* ) to avoid compiler warnings
- Erroneous assert() statment that could cause compilation failure or segfault in ValueSpecialWidgetX62.cpp.
- Command line option --force-slave-address. Its meaning for ddcui is the same as for ddcutil. See Option: --force-slave-address and section Device Busy (EBUSY) Errors on the ddcutil web site.
- Command line option --disable-force-slave-address disables the setting in case it has been enabled by shared library configuration.
- If monitor communication fails because of Linux error EBUSY, the Summary view reports it as "Busy" instead of "Invalid" suggests use of option --force-slave-address.
- The Capabilities and Feature views for monitor cannot be selected if it doesn't support DDC/CI, or if the the capabilities string cannot be read.
- Disable all view selection if no monitor is detected.
- More consistently use the term "display" instead of "Monitor" in the user interface.
- ddcui recognizes environment variable DDCUTIL_DEBUG_PARSE to enable tracing in command line parsing without recompiling.
- CMakeLists.txt has been extensively updated.
- The minimum supported version is specified as 3.10, as that is known to work. If need be, CMakeLists.txt can be edited to specify an earlier version and the script will likely still work.
- The script uses command line option --log-level to control message output. Message level VERBOSE is new as of cmake 3.15. If the script is being executed on an earlier version, messages marked VERBOSE are treated as STATUS.
- Command line option --use-cache controls whether ccache is used to speed builds (assuming it is installed). The default is --use-ccache=yes.
- Building in the source directories is not allowed.
- Better support for cmake variable CMAKE_BUILD_TYPE. The default value is RelWithDebInfo. Validation of the supplied value has been factored out into file validate_CMAKE_BUILD_TYPE.cmake.
- Requires glib version at least 2.40 for function g_option_context_strv().
- Segfaults
- In particular, handle the pathological case, reported for Gentoo, where glib function g_option_context_parse_strv() fails but does not return an error message.
- Numerous memory leaks
- Code simplification, particularly for display initialization and error message propogation
- The "Use Latest Feature Values" setting in the NC Feature Values dialog, and corresponding command line option --use-latest-nc-values. This feature was hard to document and convoluted to implement. Instead, the User Defined Features facility allows for definition of the possible NC feature values for a monitor feature.
This log summarizes user visible changes in ddcui.
Though the list of changes is short, in fact the code base has been extensively reworked.
For details, see ddcui Release Notes.
- Support VCP features, e.g. x62 (Audio Balance), that have both a continuous range. and a set of special values. The widget for these features has both a slider/spinbox for the continuous range, and a combo-box for the special values.
- Desktop integration
- Install ddcui.desktop in /usr/share/applications
- Install icons in /usr/share/icons/hicolor, /usr/share/pixmaps
- Install ddcui.appdata.xml in /usr/share/metainfo
- Configuration file, typically $HOME/.config/ddcutil/ddcutilrc, which is shared with ddcutil and libddcutil.
- Special handling for unrecognizd NC feature values
- When obtaining the value id and names for a feature, ddcui normally uses the values and names specified for the monitor's MCCS version. Sometimes monitors use feature values defined in a later version. The Use Latest MCCS Values checkbox in the NC Feature Values dialog specifies that the NC value table for the highest applicable MCCS version be used. This can also be specified by command line option --force-latest-nc_value-names.
- Handle the case where a monitor reports a NC value that is not in the MCCS or capabilities list.
- Menubar option Actions->Redetect Monitors tells libddcutil to redetect displays. The caller should replace its data structures to reflect the new list of monitors.
- Use "video-display" icon from Oxygen theme
- Rename the "Other Options" dialog to "NC Feature Values"
- Revise and extend help screen content
- User interface cleanup
- Command line option --help does not report deveelopment related options. Use --help-developmen or --help-all.
- qmake is no longer supported, use cmake
- Command line options affecting only libddcutil that can be specified instead in configuration file ddcutilrc: --udf, --no-udf, --nousb, --maxtries, --sleep-multiplier, --sleep-less, --less-sleep, --no-less-sleep, --dynamic-sleep-adjustment
