conky

Name

conky — a system monitor for X originally based on the torsmo code, but more kickass.

Synopsis

conky [options]

Description

Conky is a system monitor for X originally based on the torsmo code. Since it's original conception, Conky has changed a fair bit from it's predecessor. Conky can display just about anything, either on your root desktop or in it's own window. Conky has many built-in objects, as well as the ability to execute programs and scripts, then display the output from stdout.

We are always looking for help, and anyone interested in becoming a developer is welcome. Please use the facilities at SourceForge to make bug reports, feature requests, and submit patches.

Thanks for your interest in Conky.

Compiling

First, make sure you have the X development libraries installed, this should be a package along the lines of "libx11-dev or xorg-x11-dev". Gentoo users, Conky is in Gentoo's Portage. Simply use "emerge conky" for installation. There is also usually an up-to-date ebuild within Conky's package or in CVS.

To compile and run Conky with all optional components:

sh autogen.sh # Only required if building from CVS
./configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/ share --sysconfdir=/etc --localstatedir=/var/lib --enable-double-buffer --enable-own-window --enable-proc-uptime --enable-mpd --enable-xft --enable-seti
make
make install # Optional
./conky

Conky doesn't probably compile with other compilers than gcc and icc. It doesn't compile with C89 compiler and not even with pure C99. It uses few things that might not exist: strdup(), strcasecmp(), strncasecmp(), optarg variable with getopt() and long long (not in C89). Crashes in file system statistics stuff when compiled with icc, I don't know exactly why.

You can disable 'drawing to own window' feature in case you don't need it by passing --disable-own-window to configure -script.

You Should Know

Conky is generally very good on resources. However, certain objects in Conky are harder on resources then others. In particular, the $tail, $top, $font, and $graph objects are quite costly in comparison to the rest of Conky.

If you do use them, please do not complain about memory or CPU usage, unless you think something is going seriously wrong (mem leak, et cetera).

Options

Command line options override configurations defined in configuration file.

-V: Prints version and exits
-a ALIGNMENT: Text alignment on screen, {top,bottom}_{left,right} or none
-b: Use double buffering (eliminates "flicker")
-c FILE: Config file to load instead of $HOME/.conkyrc
-d: Daemonize Conky, aka fork to background
-f FONT: Font to use
-h: Prints command line help and exits
-o: Create own window to draw
-t TEXT: Text to render, remember single quotes, like -t ' $uptime '
-u SECONDS: Update interval
-w WIN_ID: Window id to draw
-x X_COORDINATE: X position
-y Y_COORDINATE: Y position

Configuration Settings

Default configuration file is $HOME/.conkyrc (can be changed from conky.c among other things). See conkyrc.sample. You might want to copy it to $HOME/.conkyrc and then start modifying it.

alignment: Aligned position on screen, may be top_left, top_right, bottom_left, bottom_right, or none
background: Boolean value, if true, Conky will be forked to background when started
on_bottom: Set conky on the bottom of all other applications

default_color: Default color and border color
default_shade_color: Default shading color and border's shading color
default_outline_color: Default outline color
double_buffer: Use the Xdbe extension? (eliminates flicker) It is highly recommended to use own window with this one so double buffer won't be so big.
draw_borders: Draw borders around text?
draw_shades: Draw shades?
draw_outline: Draw outlines?
font: Font name in X, xfontsel can be used to get a nice font
gap_x: Gap between right or left border of screen, same as passing -x at command line

text: After this begins text to be formatted on screen

Variables

Colors are parsed using XParsecolor(), there might be a list of them: /usr/X11R6/lib/X11/rgb.txt. Also, http://sedition.com/perl/rgb.html Color can be also in #rrggbb format (hex). Note that when displaying bytes, power is 1024 and not 1000 so 1M really means 1024*1024 bytes and not 1000*1000.

~/.conkyrc default configuration file

Bugs

Drawing to root or some other desktop window directly doesn't work with all window managers. Especially doesn't work well with Gnome and it has been reported that it doesn't work with KDE either. Nautilus can be disabled from drawing to desktop with program gconf-editor. Uncheck show_desktop in /apps/nautilus/preferences/. There is -w switch in Conky to set some specific window id. You might find xwininfo -tree useful to find the window to draw to. You can also use -o argument which makes Conky to create its own window.
