I have gimp 3.04 on fedora 42. G’mic version 3.5.4pre. When Trying to use the G’MIC extract foreground (interactive) I get the following:
*** Error in ./fx_extract_foreground/*foreach/*substitute/x_segment/ *** Command ‘x_segment’: No display available.
Not sure if its relevant but I have laptop display plus an external HDMI connected display. Intel integrated graphics. The error comes up when I click ‘apply’, which on the video I watched, is supposed to bring up an interactive screen where you can indicate what is inside and outside the foreground.
