I've have the latest version of kde and XFree86 and there is
still a problem when i'm connected to the internet using
kppp. The problem is that the X server (i use the Mach64
server) is refusing connection to all X applications so
before going on the web i've have to start all applications
i want to use during my kppp session.
This is actually not a problem with kppp or even KDE itself, but
rather with CORBA. CORBA is trying to perform a reverse lookup of the
hostname before starting any applications. I am assuming that your
hostname is currently set to localhost.localdomain. This being the
case, then you dial up to your ISP, the network scripts that get
executed are assigning you a new hostname, and therefore CORBA is not
able to perform that reverse lookup anymore and you see what happens.
To solve this problem, give your machine a real hostname (check "man
hostname") and then add this entry to your /etc/hosts file (mimic the
entry which is already there for localhost) This way when you dial
up, you will not get a new hostname (since you have already assigned
one) and CORBA will be able to perform the reverse lookup because the
assignment is given in /etc/hosts.
