Ok, I think I've got this sorted out. Three things:
Thanks, Paul. I wish I had the time to dig deeply into LaTeX, LyX, and PSTricks.
1. If you move the LaTeX code to a standard environment above the title, you'll get the logo on the title page as well as on the slides.
OK. Makes sense now that I think about it.
2. The \pgfdeclareimage command does not appear to accept clipping and bounding arguments, so if you want to use that, you'll need to redo the image in a way that fills up the page it's drawn on in the source document. (There may be some sneaky way to bound and clip with \pgfdeclareimage, but I haven't yet found the docs for it, so all I know is that it rejects bounding box options if they're put in the same optional argument where you have the height ... unless I'm munging the syntax.}
Perhaps it's that pdf files have bounding box arguments incorporated that has caused the problems. In prior presentations I used the .eps form of the logo, but that didn't work here, either.
3. Your syntax is fine. It will work (other than the clipping issue) if you export a .tex file and run pdflatex manually. The reason for the "institution-logo" text is indeed that, as I suspected, PGF can't find the logo. The reason it can't find the logo is that LyX is not copying the image files to the temp buffer, because the image file is only mentioned in a \pgfdeclareimage command, which LyX does not parse. If I make the path absolute and then View -> PDF from LyX, it works (except that the image is miniscule due to the clipping/bounding issue).
That's interesting. Perhaps when I get back and have time I'll look more deeply into this. In the View menu I have three pdf options: dvipdfm, pdflatex, and ps2pdf. With the original syntax none of the three produce the logo. Also, exporting to a .tex file using the pdflatex option rather than the plain TeX option also doesn't work here.
