In Ubuntu the path variable is stored in /etc/environment. 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?
