4.2.7 Common Linux Problems
I can't change settings in the
configuration tool.
You need to have administrator privileges to be able
to change global settings.
I am using the KDE
desktop but the configuration tool
and LLPR won't start.
You may not have the GTK libraries installed. These
usually come with most Linux distributions, but you
may have to install them manually. Refer to your
distribution's installation manual for more details
about installing additional packages.
I just installed this
package but can't find entries in
the KDE/ Gnome menus.
Some versions of the KDE or GNOME desktop
environments may require that you restart your
session for the changes to take effect.

I can't make a printer
the system default.
In some conditions, it may not be possible to change
the default queue. This happens with some variants
of LPRng, especially on recent RedHat systems that
use the "printconf" database of queues.
When using printconf, the /etc./printcap file is
automatically refreshed from the database of printers
managed by the system (usually through the
"printtool" command), and the queues in /etc./
printcap.local are appended to the resulting file. The
default queue in LPRng is defined as the first queue
in /etc./printcap, and therefore it is not possible for
the Linux Printer Package to change the default when
some queues have otherwise been defined using
printtool.
LPD systems identify the default queue as the one
named "lp". Thus, if there is already a queue by this
name, and if it doesn't have an alias, then you won't
be able to change the default. To work around this,
you can either delete the queue or rename it by
manually editing the /etc./printcap file.
