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
allow_lab_output | bool | false | allow XYZ and Lab color spaces as output
this is mainly useful for debugging and to create colorchecker lut styles externally.
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 / discarding history stack
always ask the user before any image file is deleted / history stack is discarded.
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.
ask_before_rmdir | bool | false | ask before removing empty folders
always ask the user before removing any empty folder. this can happen after moving or deleting images.
bauhaus/scale | float | 1.4 | widget scale
scaling factor for bauhaus widgets, will affect font size
brush_smoothing | enum low medium high | medium | smoothing of brush strokes
sets level for smoothing of brush strokes. stronger smoothing leads to less nodes and easier editing but with lower control of accuracy.
cache_color_managed | bool | true | color manage cached thumbnails
if enabled, cached thumbnails will be color managed so that lighttable and filmstrip can show correct colors. otherwise the results may look wrong once the display profile gets changed.
cache_disk_backend | bool | true | enable disk backend for thumbnail cache
if enabled, write thumbnails to disk (.cache/darktable/) when evicted from the memory cache. note that this can take a lot of memory (several gigabytes for 20k images) and will never delete cached thumbnails again. it's safe though to delete these manually, if you want. light table performance will be increased greatly when browsing a lot. to generate all thumbnails of your entire collection offline, run 'darktable-generate-cache'.
cache_memory | int64 | (1024 * 1024 * 256) | memory in megabytes to use for thumbnail cache
this controls how much memory is going to be used for thumbnails and other buffers (needs a restart).
channel_display | enum false color grey scale | false color | display of individual color channels
defines how color channels are displayed when activated in the parametric masks feature.
codepaths/openmp_simd | bool | false | enable usage of OpenMP SIMD codepaths. if enabled, and such codepath exists, it will have the highest priority
codepaths/sse2 | bool | true | enable usage of SSE2-optimized codepaths
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.
darkroom/ui/overexposed/colorscheme | int | 1 |
darkroom/ui/overexposed/lower | float | 2.0 |
darkroom/ui/overexposed/upper | float | 98.0 |
darkroom/ui/rawoverexposed/colorscheme | int | 0 |
darkroom/ui/rawoverexposed/mode | int | 0 |
darkroom/ui/rawoverexposed/threshold | float | 1.0 |
darkroom/ui/scale_precise_step_multiplier | float | 0.1 | the multiplier that is applied to any slider precise value change
any slider value change will be multiplied by this number, when changing slider while holding CTRL modifier
darkroom/ui/scale_rough_step_multiplier | float | 10.0 | the multiplier that is applied to any slider rough value change
any slider value change will be multiplied by this number, when changing slider while holding SHIFT modifier
darkroom/ui/scale_step_multiplier | float | 1.0 | the multiplier that is applied to any slider value change
any slider value change will be multiplied by this number, when changing slider while NOT holding SHIFT or CTRL modifiers
darkroom/ui/scroll_to_module | bool | true | scroll to darkroom modules when expanded/collapsed
when this option is enabled then darktable will try to scroll the module to the top of the visible list
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/expose_statuses | bool | false | always show thumbnail overlays
show overlays (rating stars, "edited" mark, etc) for all thumbnails in file manager, not only hovered one
lighttable/ui/scroll_to_module | bool | false | scroll to lighttable modules when expanded/collapsed
when this option is enabled then darktable will try to scroll the module to the top of the visible list
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 | 10000 | assumed maximum sane number of tiles
if during tiling this number is exceeded darktable assumes that tiling is not possible and falls back to untiled processing - with all system memory limits taking full effect. in case you want to process huge images you may want to increase this number.
metadata/resolution | int | 300 |
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.
omit_tag_hierarchy | bool | false | omit hierarchy in simple tag lists
when exporting images the hierarchical tags are also added as a simple list of non-hierarchical ones to make them visible to some other programs. when this option is checked darktable will only include their last part and ignore the rest. so 'foo|bar|baz' will only add 'baz'.
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_checksum | string |  | checksum representing the setup of opencl devices on this computer
darktable re-checks the performance benchmarks of your system in case your setup has changed, which is indicated by a change versus the stored checksum in this config variable; darktable de-activates opencl if the GPU benchmark lies below the one of the CPU.
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_disable_drivers_blacklist | bool | false | whether to allow some partial opencl implementations to be used or not
not all opencl implementations are fully-functional, there are at least two, which are not production-quality yet: pocl and beignet; therefore at this point in time, it is better to explicitly blacklist them by default. can be changed by setting this configuration option to TRUE (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_mandatory_timeout | int | 200 | timeout period for locking mandatory opencl device
time period (in units of 5ms) after which we give up try-locking an opencl device for mandatory use. defaults to 200.
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_scheduling_profile | enum default multiple GPUs very fast GPU | default | OpenCL scheduling profile
defines how preview and full pixelpipe tasks are scheduled on OpenCL enabled systems. default - GPU processes full and CPU processes preview pipe (adaptable by config parameters); multiple GPUs - process both pixelpipes in parallel on two different GPUs; very fast GPU - process both pixelipes sequentially on the GPU.
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 transferred 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 | 350 | width of the side panels in pixels
(needs a restart)
performance_configuration_version_completed | int | 0 | version of the last completed performance configuration
what was the last performance configuration which has been completed
pixelpipe_synchronization_timeout | int | 200 | timeout period of pixelpipe synchronization
time period (in units of 5ms) after which synchronization of preview and full pixelpipe is assumed to have failed. set to zero to omit pixelpipe synchronization. defaults to 200.
please_let_me_suffer_by_using_32bit_darktable | bool | false | if using a 32-bit build, hide the message recommending a 64-bit build
the 32-bit build of darktable is known to exhibit sporadic issues and crashes. we show a warning message hinting at this issue. with this option, you can suppress the warning.
