could you try adding the following line "IBM; IBM Analog Flatpanel; IBM252f; 30.0-82.0; 56.0-75.0; 1" to /usr/share/ldetect-lst/MonitorsDB ?
format is "VendorName; ModelName; EISA_ID; HorizSync_Range; VertRefresh_Range; dpms_support?"
you can get your monitor's EISA ID by running the following command: ddcxinfos | fgrep -i eisa i suppose this is how you get IBM252f ?
the 1 at end of line must be kept *only* if your monitor support dpms for power saving.
put the proper name instead of "IBM Analog Flatpanel" since i do not think this is what would be the model name.
if you send me back the right line, i'll add support for your monitor in the monitor database
IBM; IBM T85A; IBM252f; 30.0-82.0; 56.0-75.0; 1
I will submit more that are missing. (Got many flatpanels that are not working).
