[arch-general] Lyx and texlive don't allow viewing the document as pdf, ps, or dvi

Hello, I have installed lyx, and texlive (from community). I am now (I had tetex earlier and it was working fine) unable to view my documents by clicking View -> DVI or View -> PDF or by clicking the PDF, DVI, and PS buttons on the toolbar. I keep getting the error dialog box "File does not exist: /tmp/lyx_tmpdir[random letters and numbers]/lyx_tmpbuf0/foo.dvi" or "blah: blah/foo.pdf" or "blah: /blah/foo.ps". Does anyone know how I may solve this problem? I could go back to tetex, but I'd feel more satisfied with finding a solution to the problem, so here I am :) . Thank you ravster.
