I have a Thinkpad T40 which has some function keys for browsing (forward and
back) near the cursor keys which I used for switching desktops in XFCE. Since
the upgrade to XFCE 4.0.4, these stopped working.
They are also not detected by xev anymore. They still work flawlessly in Gnome.
Nothing changed in this matter. As if xev doesn't return the keysym, then
you're missign a couple of xmodmap definitions.
I see no bug with xfce here.
