In Ubuntu the path variable is stored in /etc/enviorment. This is mine (I've made no changes to it, this is the system default):

$ cat /etc/environment 
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"

but when I examine my PATH variable:

$ echo $PATH
/home/dan/bin:/home/dan/bin:/bin:/usr/bin:/usr/local/bin:/usr/bin/X11

You'll notice /usr/games is missing (it was there up until a few days ago). My /etc/profile makes no mention of PATH. My ~/.profile is the default and only has:

if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

This only happens in gnome, not in tty1-6. This is missing from both gnome terminal and when I try to call applications from the applications dropdown. Anyone know what could be causing this?

Thanks.
