WHAT IS CONKY?
|
|
|
|
Conky is a system monitor for Linux that sits in the corner of your
|
|
desktop. Conky renders itself on the root window (on the desktop) or to
|
|
its own transparent window any special eyecandy.
|
|
Conky can show lots of info about your system, including:
|
|
|
|
* kernel version
|
|
* uptime
|
|
* network interface information
|
|
* memory and swap usage
|
|
* hostname
|
|
* machine, i686 for example
|
|
* system name, Linux for example
|
|
* temperatures from i2c-sensors
|
|
|
|
THINGS 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 and
|
|
$top 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,
|
|
because you will simply be ignored.
|
|
|
|
With that out of the way, if you have a better way of doing something,
|
|
please submit a patch for Conky. I know I am certainly not the world's
|
|
best programmer, and I still have a lot to learn.
|
|
|
|
COMPILING
|
|
|
|
To compile and run Conky with all optional components (If you run Gentoo, see the "Ebuild" Section below):
|
|
|
|
./configure --prefix=/usr --enable-xft --enable-mpd --enable-seti --enable-double-buffer --enable-own-window --enable-proc-uptime
|
|
make
|
|
./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.
|
|
|
|
EBUILD
|
|
|
|
Conky is in Gentoo's Portage. Simply use "emerge conky" to install conky.
|
|
|
|
CONFIGURING
|
|
|
|
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.
|
|
|
|
Configuration file confs
|
|
|
|
Conf Meaning
|
|
alignment Aligned position on screen, may be top_left,
|
|
top_right, bottom_left, bottom_right

|
|
Use the Xdbe extension? (eliminates flicker) It is
|
|
double_buffer highly recommended to use own window with this one
|
|
so double buffer won't be so big.
|
|
draw_borders Draw borders around text?

|
|
draw_outline Draw outlines?
|
|

|
passing -x at command line
|
|
gap_y Gap between top or bottom border of screen, same as

top type, num This takes arguments in the form:

|
|
|
|
Note that when displaying bytes, power is 1024 and not 1000 so 1M really
|
|
means 1024*1024 bytes and not 1000*1000.
|
|
|
|
KNOWN PROBLEMS
|
|
|
|
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.
|
