after installing and activating the gedit-latex-plugin the latex menu doesn't appear in the menu bar and you can't compile etc (latex->pdf in the tools menu is grayed out).
the menu can be retrieved by doing the following:
edit -> preferences -> plugins -> latex plugin 0.2 -> configure plugin
-> tools -> "latex->pdf" -> properties -> ok
not change anything, and just leaves these menus. the latex menu is back and you can compile etc.
had the same problem with xubuntu 11.04 when i tried it. then it just appeared in ubuntu.
