you need to be running a service called gpm, this provides console mouse services
service gpm start
then check if the service is enabled in your runlevels with...
[root@localhost]# chkconfig --list gpm
gpm 0:off 1:off 2:on 3:on 4:on 5:on 6:off
if it says off in all your runlevels you can turn it on again with..
chkconfig --levels 2345 gpm on
i hope thats helps
