[tdh@wont ~]$ jjj Command not found.
Followed by an annoying lag. FC13 does not do this, but FC14 does.
It turns out there is a package called PackageKit-command-not-found and it is controlling this behavior.
[root@wont PackageKit]# pwd /etc/PackageKit [root@wont PackageKit]# diff CommandNotFound.conf CommandNotFound.conf.STOCK 35c35 < SoftwareSourceSearch=false --- > SoftwareSourceSearch=true
And problem solved! I.e., I want to keep the other features of the package (for now), so this gives the solution with the least impact.
