If in Tools > Preferences you search for "viewer", one result is File Handling > File Formats. Select the PDF format from the dropdown box at the top, and then put in the binary name of your PDF viewer. Unfortunately, if you have to use multiple PDF formats, you must change it for all. > I made Foxit the default pdf viewer, but Lyx still seems to ignore it. Do you mean at the OS level? indeed, I think someday we will add support for xdg-open or something like that, but right now we don't have it. > Incidentally, I tried to find in the Texworks preferences where the > pdf viewer is specified, but I was unable to find it. > So, sadly, Lyx is still dead (for me). LyX seems to be alive on your system! It is just not able to communicate. What is the binary name of Foxit Reader? Did Lubuntu install a PDF reader and you removed it or it really does not install a PDF reader in the base installation? Scott
