darktablerc

this files gives an overview over the default settings of the darktable configuration found in ~/.config/darktable/darktablerc. you might find some extra values in that configuration file that get generated by the code at runtime, this overview only has the default values that are specified during compile time. some details (like allowed range and factors when shown in the preferences dialog) are not shown here to not clutter the list too much. please have a look at the corresponding source file for up-to-date information.

key | type | default | description
ask_before_copy | bool | true | ask before copying images to new film roll folder
| always ask the user before any image file is copied.
ask_before_delete | bool | true | ask before erasing images from disk
| always ask the user before any image file is deleted.
ask_before_move | bool | true | ask before moving images from film roll folder
| always ask the user before any image file is moved.
ask_before_remove | bool | true | ask before removing images from database
| always ask the user before any image is removed from DB.
bauhaus/scale | float | 1.4 | widget scale
| scaling factor for bauhaus widgets, will affect font size
cache_compression | enum off low quality (fast) high quality (slow) | off | compression of thumbnail images
| off - no compression in memory, JPG on disk. low quality - DXT1 (fast). high quality - DXT1, same memory as low quality variant but slower.
cache_memory | int64 | (1024 * 1024 * 512) | memory in megabytes to use for mipmap cache
| this controls how much memory is going to be used for thumbnails and other buffers (needs a restart).
compress_xmp_tags | enum never always only large entries | only large entries | store xmp tags in compressed format
| entries in xmp tags can get rather large and may exceed the available space to store the history stack in output files. this option allows xmp tags to be compressed and save space.
config_version | int | 0 | version of these dt-GConf entries
| if this number is smaller than the darktable internal version number, the values here will be synched with the new defaults.
darkroom/ui/overexposed/colorscheme | int | 1 |
darkroom/ui/overexposed/lower | float | 2.0 |
darkroom/ui/overexposed/upper | float | 98.0 |
darkroom/ui/single_module | bool | TRUE | expand a single darkroom module at a time
| this option toggles the behavior of shift clicking in darkroom mode
database | string | library.db | database location
| filename relative to ~/.config/darktable or starting with a slash (needs a restart).
database_cache_quality | int | 89 | JPEG quality of on-disk thumbnails
| affects only the thumbnail cache used for quick startup.
host_memory_limit | int | 1500 | host memory limit (in MB) for tiling
| this variable controls the maximum amount of memory (in MB) a module may use during image processing. lower values will force memory hungry modules to process image with increasing number of tiles. setting this to 0 will omit any limit. values below 500 will be treated as 500 (needs a restart).
lighttable/ui/single_module | bool | FALSE | expand a single lighttable module at a time
| this option toggles the behavior of shift clicking in lighttable mode
maximum_number_tiles | int | 500 | assumed maximum sane number of tiles
| if during tiling this number of tiles is exceeded darktable assumes something went wrong. in case you want to process huge images (like gigapixel panoramas) you may try to increase that limit. as this has never been tested by the developers you are on your own. please report back your successes or failures.
never_use_embedded_thumb | bool | false | don't use embedded preview JPEG but half-size raw
| check this option to not use the embedded JPEG from the raw file but process the raw data. this is slower but gives you color managed thumbnails.
opencl | bool | true | activate OpenCL support
| if found, use OpenCL runtime on your system for improved processing speed. can be switched on and off at any time.
opencl_async_pixelpipe | bool | false | run OpenCL pixelpipe asynchronously
| if set to TRUE OpenCL pixelpipe will not be synchronized on a per-module basis. this can improve pixelpipe latency. however, potential OpenCL errors would be detected late; in such a case the complete pixelpipe needs to be reprocessed instead of only a single module. export pixelpipe will always be run synchronously.
opencl_avoid_atomics | bool | false | do not run OpenCL kernels which require atomic operations
| if set to TRUE darktable will not use OpenCL kernels which contain atomic operations (example bilateral). pixelpipe processing will be done on CPU for the affected modules. useful if your OpenCL implementation freezes/crashes on atomics or if they are processed with a bad performance.
opencl_device_priority | string | */!0,*/*/* | priority of OpenCL devices for each pixelpipe type
| defines priorities on how (multiple) OpenCL devices are allocated to the different types of pixelpipe (full, preview, export, thumbnail). for more details visit our usermanual (needs a restart).
opencl_library | string |  | system library with OpenCL runtime
| OpenCL runtime library is normally detected automatically by darktable. if your OpenCL runtime is at an unusual place and cannot be detected, enter the full pathname here. leave empty for default behavior.
opencl_memory_headroom | int | 300 | amount of OpenCL memory (in MB) which we assume as being reserved for the driver
| this amount of memory (in MB) will be substracted from total GPU memory in order to calculate the available OpenCL memory. too low values will lead to out-of-memory situations in OpenCL processing. too high values will lead to unnecessary tiling (needs a restart).
opencl_memory_requirement | int | 768 | minmum amount of GPU memory (MB) required to activate OpenCL
| OpenCL will only be activated if your graphics card has at least this amount of memory. reducing the value will allow cards with less GPU memory to be used - but at the risk of lower system stability and occasional crashes. values below 200 will be treated as 200.
opencl_micro_nap | int | 1000 | pause OpenCL processing for this number of microseconds from time to time
| for slow GPUs this gives your graphics driver some time to breathe to do needed screen updates. can be left at zero for fast devices.
opencl_number_event_handles | int | 25 | the number of OpenCL event handles darktable can use
| a positive non-zero integer defines the number of event handles that darktable may have opened on a device. a value of -1 does not pose any restrictions, bearing the risk of hitting the device's resource limits. a value of zero completely prevents the use of event handles.
opencl_size_roundup | int | 16 | round OpenCL work group sizes to a multiple of
| in OpenCL processing round width/height of global work groups to a multiple of this value. reasonable values are powers of 2. this parameter can have high impact on OpenCL performance.
opencl_synch_cache | bool | false | copy back OpenCL buffers into pixelpipe cache after each module
| this brings pixelpipe cache and OpenCL buffers in synch after each module. on slow GPUs this might improve speed as it avoids reprocessing the whole pixelpipe on every parameter change. on fast GPUs the additional memory transfer overhead will slow down OpenCL considerably.
opencl_use_cpu_devices | bool | false | whether to make use of CPU OpenCL devices
| typically darktable's hand-optimized CPU code is much faster than any OpenCL-on-CPU code; therefore CPUs are excluded from being used as OpenCL devices by default. can be changed by setting this configuration option to TRUE (needs a restart).
opencl_use_pinned_memory | bool | false | whether to use pinned memory transfer during tiling
| during tiling huge amounts of memory need to be transfered between host and device. for some OpenCL implementations direct memory transfers give a drastic performance penalty. this can often be avoided by using indirect transfers via pinned memory. other devices have more efficient direct memory transfer implementations. AMD seems to belong to the first group, nvidia to the second.
panel_width | int | 298 | width of the side panels in pixels
| (needs a restart)
parallel_export | int | 1 | export multiple images in parallel
| set this variable to num_threads if you want multithreaded export to process multiple images at a time. be warned: every thread will need at the very least 1GB of memory. setting this to 1 switches on per-image parallelization.
plugins/capture/backup/enable | bool | false | flag if backup of imported images should be performed
plugins/capture/backup/foldername | string | photos | the name of backup directory to search for on mounted medias
plugins/capture/backup/warn | bool | false | flag if user should be interactivly warned about non present backup destinations
