Binary package hint: xorg
When my xfce4 session finishes, instead of getting back to kdm (I use kubuntu.... but my kde is broken right now, so I'm using xfce in the meantime), I'm welcomed by the VTs
I checked xorg's logs and it's because there's a crash.
By the way, I'm using vesa cause I'm having problems with intel's driver (in case you are interested as well)
