@irfanjunaid I have never tried this on Debian 12 - maybe it ships an old version of fprintd that doesn't work very well with the out-of-tree drivers?

Yeah, it seems like it has something to do with the fprintd. Everything works perfectly on Ubuntu Noble and Jammy but not in Debian. I will try testing with different versions of the driver and fprintd. Thank you again for this script @giannello 👍
