On Debian 10 (Buster), running latex does not cause refresh of xdvi, as I seem to recall that it does on Debian 8 and 9. Instead, I must click on the screen for refresh.
Having read the xdvi man page, I think this could be corrected by invoking: xdvi -watchfile 1 <filename.tex> & when starting xdvi; but that was not necessary on either Jessie or Stretch. Working as much as possible from the keyboard, I find the necessity of reaching for the rodent a significant nuisance. Has something changed?
