What you could try:
- copy /usr/share/lensfun/v1/compact-panasonic.xml to
~/.local/share/lensfun/v1 (under a new name)
- edit that copy to include the proper camera and change the lens name
"DMC-LX100" to whatever your camera reports.
- save the edits, and (re)start darktable
or see http://lensfun.sourceforge.net/calibration-tutorial/lens-calibration.html
disclaimer: the above is a summary of what has been reported in this list in
earlier threads, I never needed to try this. That said, if things go pear-
shaped, delete the copy in ~/.local/share/lensfun/v1 and you should be back
where you started.
An alternative would be to create your own correction profile using Hugin.
E.g. http://hugin.sourceforge.net/tutorials/calibration/en.shtml describes how
to do this (take care when collecting the images you need!).
