X11 utilities An X client is a program that interfaces with an X server (almost always via the X libraries), and thus with some input and output hardware like a graphics card, monitor, keyboard, and pointing device (such as a mouse). This package provides a miscellaneous assortment of X utilities that ship with the X Window System, including: - appres, editres, listres and viewres, which query the X resource database; - luit, a filter that can be run between an arbitrary application and a UTF-8 terminal emulator; - xdpyinfo, a display information utility for X; - xdriinfo, query configuration information of DRI drivers; - xev, an X event displayer; - xfd, a tool that displays all the glyphs in a given X font; - xfontsel, a tool for browsing and selecting X fonts; - xkill, a tool for terminating misbehaving X clients; - xlsatoms, which lists interned atoms defined on an X server; - xlsclients, which lists client applications running on an X display; - xlsfonts, a server font list displayer; - xmessage, a tool to display message or dialog boxes; - xprop, a property displayer for X; - xvinfo, an Xv extension information utility for X; - xwininfo, a window information utility for X; The editres and viewres programs use bitmap images provided by the xbitmaps package. The luit program requires locale information from the libx11-data package.
