Three clipboard managers are available:
xclipboard
The clipboard manager traditionally distributed with X. xclipboard handles
plain text only.
5.6
90 Chapter 5: Using the X Server
Klipper
The KDE clipboard manager. Installed by default with KDE, klipper does not
interfere with the more recent clipboard action as long as the source client (the
one supplying the data) stays running, which lets you do an immediate cut/copy
and paste with content negotiation. All other paste operations are in one format
only (e.g., when pasting text, formatting and attributes will be lost).
Gnome-clipboard-manager
The Gnome equivalent of klipper. This project was discontinued in 2004 but the
software is still available
Various projects on freedesktop.org are focused in improving the clipboard system.
Although the clipboard mechanism can be used with all types of data??”including
images, sound, and video??”very few applications support data types other than text.
For a simple example of pasting an image, you can copy an image from Firefox and
paste it into OpenOffice.
Pasting with the clipboard and pasting using a middle mouse click
(Section 5.4) work in an almost identical manner: the X server facilitates
the data transfer directly from the source client (select/cut/copy)
to the destination client (paste).
