Conky is a system monitor software for the X Window System. It is available for GNU/Linux and FreeBSD. It is free software released under the terms of the GPL license. Conky is able to monitor many system variables including CPU, memory, swap, disk space, temperature, top, upload, download, system messages, and much more. It is extremely configurable, however, the configuration can be a little hard to understand. Conky is a fork of torsmo.

When editing your config file, you will see immediately the effect of any change as soon as you save it. There is no need to log out/log in your X session. So best is to test all kind of options, one by one, save the configuration file and see the change on your conky window, and correct if your change is unappropriated.

Conky needs Double Buffer Extension (DBE) support from the X server to prevent flickering because it cannot update the window fast enough without it. It can be enabled in {{ic|/etc/X11/xorg.conf}} with {{ic|Load "dbe"}} line in {{ic|Section "Module"}}. The xorg.conf file has been replaced (1.8.x patch upwards) by {{ic|/etc/X11/xorg.conf.d}} which contains the particular configuration files. ''DBE'' is loaded automatically.

Aside the classic preset colors (white, black, yellow...), you can set your own custom color using the color name code. To determine the code of a color, use a color selector app. The basic {{pkg|gcolor2}} package in the [[Official Repositories|official repositories]] will give you the color name. It is made of a series of letters and numbers.

=== Fix scrolling with UTF-8 multibyte characters ===

The current version of conky (1.9.0) suffers from a bug (http://sourceforge.net/p/conky/bugs/341/) where scrolling text increments by byte, not by character, resulting in text containing multibyte characters to disappear and reappear while scrolling.  A package with a patch fixing this bug can be found in the AUR: {{AUR|conky-utfscroll}}

If you notice that your conky fonts appear smaller than they should, or they don't align properly, it could be caused by a default setting in the infinality freetype2 patch.  This setting can cause some programs to display fonts at 72 DPI instead of 96 even if the rest of your system is set to 96. If you notice a problem open {{ic|/etc/fonts/infinality/infinality.conf}}  search for the section on DPI and change 72 to 96.

Revision as of 00:51, 19 September 2013

Conky is a system monitor software for the X Window System. It is available for GNU/Linux and FreeBSD. It is free software released under the terms of the GPL license. Conky is able to monitor many system variables including CPU, memory, swap, disk space, temperature, top, upload, download, system messages, and much more. It is extremely configurable, however, the configuration can be a little hard to understand. Conky is a fork of torsmo.

Installation and configuration

When editing your config file, you will see immediately the effect of any change as soon as you save it. There is no need to log out/log in your X session. So best is to test all kind of options, one by one, save the configuration file and see the change on your conky window, and correct if your change is unappropriated.

  • Alternatively, you can use the default config at /etc/conky/conky.conf:
$ cp /etc/conky/conky.conf ~/.conkyrc

Best is to use a local ~/.conkyrc config. As many apps, conky will first try to look for a local .conkyrc file. If this one doesn't exist, then it will read the default one in /etc/conky.

In case you store your configuration locally, e.g. in your home directory, you will not be able to read any log files unless you do some changes. One of the nice features of conky is to pipe to your desktop some /var/log/ files to read all kinds of log messages. Most of these files can only be read by root, and you will thus need to sudo conky. Starting conky as root is not recommended, so you will need to make this following changes:

$ usermod -aG log username

You add username to the log group. Now username can read log files, and you will be able to redirect log messages with conky on your desktop.

  • If conky does not accept changes -- e.g. minimum_size -- you made to ~/.conkyrc make sure you cleared /etc/conky/conky.conf or commented out the relevant section.Best is to remove files in /etc/conky/, as conky will keep reading them and this can give you some Xorg error messages.

AUR packages

In addition to the basic conky package, there are various AUR packages available with extra compile options enabled:

  • conky-cli — Conky without X11 dependencies
|| conky-cliAUR
  • conky-lua — Conky with Lua support
|| conky-luaAUR
  • conky-lua-nv — Conky with both Lua and Nvidia support
|| conky-lua-nvAUR
  • conky-nvidia — Conky with Nvidia support
|| conky-nvidiaAUR

Tips and tricks

Enable real transparency in KDE4 and Xfce4

Since version 1.8.0, Conky suppports real transparency. To enable it add this line to ~/.conkyrc:

own_window_transparent yes

The above option is not desired with the OWN_WINDOW_ARGB_VISUAL yes option. This replaces the feh method described below.

Autostart with Xfce4

In .conkyrc file:

background yes

This variable will fork Conky to your background. If you want to make your window always visible on your desktop, sticky across all workspaces and not showing in your taskbar, add these arguments:

own_window yes
own_window_type override

The override option makes your window out of control of your window manager.

Add a ~/.config/autostart/conky.desktop:

[Desktop Entry]
Encoding=UTF-8
Version=0.9.4
Type=Application
Name=conky
Comment=
Exec=conky -d
StartupNotify=false
Terminal=false
Hidden=false

Prevent flickering

Conky needs Double Buffer Extension (DBE) support from the X server to prevent flickering because it cannot update the window fast enough without it. It can be enabled in /etc/X11/xorg.conf with Load "dbe" line in Section "Module". The xorg.conf file has been replaced (1.8.x patch upwards) by /etc/X11/xorg.conf.d which contains the particular configuration files. DBE is loaded automatically.

To enable double-buffer check to have in ~/.conkyrc:

# Place below the other options, not below TEXT or XY
double_buffer yes

Custom colors

Aside the classic preset colors (white, black, yellow...), you can set your own custom color using the color name code. To determine the code of a color, use a color selector app. The basic gcolor2 package in the official repositories will give you the color name. It is made of six hexadecimal digits (0-9, A-F). Add this line in your configuration file for a custom color:

color1     Colorname1
color2     Colorname2

Then, when editing the TEXT section, use custom color number previously defined.

Dual Screen

When using a dual screen configuration, you will need to play with two options to place your conky window. Let's say you are running a 1680X1050 pixels resolution, and you want the window on middle top of your left monitor, you will use this:

alignment top_left
gap_X 840

The alignment option is trivial, and gap_X option is the distance, in pixels, from the left border of your screen.

Do not minimize on Show Desktop

Using Compiz: If the 'Show Desktop' button or key-binding minimizes Conky along with all other windows, start the Compiz configuration settings manager, go to "General Options" and uncheck the "Hide Skip Taskbar Windows" option.

If you do not use Compiz, try editing ~/.conkyrc and adding/changing the following line:

own_window_type override

Integrate with Gnome 3

Some have experienced problems with Conky showing up under Gnome 3.

  • Add these lines to ~/.conkyrc:
own_window yes
own_window_type conky
own_window_transparent yes
own_window_hints undecorated,below,sticky,skip_taskbar,skip_pager

If you still experience problems with transparency. You could add these lines.

own_window_argb_visual yes
own_window_argb_value 255

Integrate with KDE

Conky with screenshot configuration generate problems with icons visualization. So there are some steps to follow.

  • Add these lines to ~/.conkyrc:
own_window yes
own_window_type normal
own_window_transparent yes
own_window_hints undecorated,below,sticky,skip_taskbar,skip_pager
  • If this setting is on, comment it out or delete the line:
minimum_size
  • To automatically start Conky, create this symlink:
    • KDE4:
$ ln -s /usr/bin/conky ~/.kde4/Autostart/conkylink
    • KDE3:
$ ln -s /usr/bin/conky ~/.kde/share/autostart/conkylink
  • Install the feh package which is available in the official repositories.
  • Make a script to allow transparency with the desktop

In KDE4 edit ~/.kde4/Autostart/fehconky:

#!/bin/bash
feh --bg-scale "$(sed -n 's/wallpaper=//p' ~/.kde4/share/config/plasma-desktop-appletsrc)"

In KDE3 edit ~/.kde/share/autostart/fehconky:

#!/bin/bash
feh --bg-scale $(dcop kdesktop KBackgroundIface currentWallpaper 1)

use --bg-center if you use a centered wallpaper.

  • Make it executable:
    • KDE4:
$ chmod +x ~/.kde4/Autostart/fehconky
    • KDE3:
$ chmod +x ~/.kde/share/autostart/fehconky
  • Instead of using a script, you can add the corresponding line to the bottom of ~/.conkyrc
    • For KDE4
${exec feh --bg-scale "$(sed -n 's/wallpaper=//p' ~/.kde4/share/config/plasma-desktop-appletsrc)"}
    • For KDE3
${exec feh --bg-scale $(dcop kdesktop KBackgroundIface currentWallpaper 1)}

Integrate with Razor-qt

With Conky's default configuration, its window might disappear from the desktop when you click on the latter. Add these lines to:

~/.conkyrc
own_window yes
own_window_class Conky
own_window_type normal
own_window_hints undecorated,below,sticky,skip_taskbar,skip_pager
own_window_transparent yes

Display package update information

  • Paconky - Displays package update information in a user-defined format. The output of this program can be included in Conky with the ${execpi} command.
  • Scrolling Notifications - Prints scrolling update notifications. From the author of Paconky.
  • Perl Script - Simpler and earlier script from the author of Paconky. Prints only the number of packages needing an update.
  • Python Script - Fairly configurable update notification program in Python.
  • Bash Script - Bash script for users that have enabled ShowSize.

Display weather forecast

See this thread.

Display RSS feeds

Conky has the ability to display RSS feeds natively without the need for an outside script to run and output into Conky. For example, to display the titles of the ten most recent Planet Arch updates and refresh the feed every minute, you would put this into your ~/.conkyrc in the TEXT section:

${rss https://planet.archlinux.org/rss20.xml 1 item_titles 10 }

If you want to display Arch Forum rss feed, add this line:

${rss https://bbs.archlinux.org/extern.php?action=feed&type=rss 1 item_titles 4}

where 1 is in minutes the refresh interval (15 mn is default),4 the number of items you wish to show.

Display Distrowatch Arch Linux ranking

See this thread.

Display rTorrent stats

See this thread.

Display your WordPress blog stats

This can be achieved by using the in python written extension named ConkyPress.

Display number of new emails (Gmail)

Create a file named gmail.py in a convenient location (this example uses ~/.scripts/) with the following Python code:

#!/usr/bin/env python

from urllib.request import FancyURLopener

username = 'your username'
password  = 'your password'

url = 'https://%s:%s@mail.google.com/mail/feed/atom' % (username, password)

opener = FancyURLopener()
page = opener.open(url)

contents = page.read().decode('utf-8')


ifrom = contents.index('<fullcount>') + 11
ito   = contents.index('</fullcount>')

unread = contents[ifrom:ito]

print(unread)
  1. Comment or delete print(unread), if you want to add a message, modify the script as follows
  2. Remove "print(unread)" and add
int(unread)
print(unread,"new messages in gmail")

With a Google App mail account, the above username variable must contain your domain:

username = 'user@yourdomain.com'
Note: Regular Gmail users input only your username without @gmail.com

You can also use Python's urllib as follows.

import urllib.request
from xml.etree import ElementTree as etree

# Enter your username and password below within quotes below, in place of ****.
# Set up authentication for gmail
auth_handler = urllib.request.HTTPBasicAuthHandler()
auth_handler.add_password(realm='New mail feed',
                          uri='https://mail.google.com/',
                          user= '****',
                          passwd= '****')
opener = urllib.request.build_opener(auth_handler)
# ...and install it globally so it can be used with urlopen.
urllib.request.install_opener(opener)

gmail = 'https://mail.google.com/gmail/feed/atom'
NS = '{http://purl.org/atom/ns#}'
with urllib.request.urlopen(gmail) as source:
    tree = etree.parse(source)
fullcount = tree.find(NS + 'fullcount').text
print(fullcount + ' new')

Add the following string to your ~/.conkyrc in order the check your Gmail account for new email every five minutes (300 seconds) and display:

${execpi 300 python ~/.scripts/gmail.py}

Other Methods

The same way, but with using grep and sed for filtering output of wget:

$ wget -q -O - https://mail.google.com/a/domain/feed/atom \
>                                --http-user=login@domain \
>                                --http-password=password \ 
>                                --no-check-certificate | \
> grep fullcount | sed 's/<[^0-9]*>//g'

instead of words login, domain, password you must type yours data.

Alternatively, you can use stunnel which is provided by the stunnel package.

The following configuration is taken from Conky's FAQ

Modify /etc/stunnel/stunnel.conf as follows, and then start the stunnel daemon:

# Service-level configuration for TLS server
[imap]
client = yes
accept  = 143
connect = imap.gmail.com:143
protocol = imap
sslVersion = TLSv1
# Service-level configuration for SSL server
[imaps]
client = yes
accept  = 993
connect = imap.gmail.com:993

The only thing left is our ~/.conkyrc:

imap localhost username * -i 120 -p 993
TEXT
Inbox: ${imap_unseen}/${imap_messages}

Here I used * as the password for Conky to ask for it at start, but you do not have to do it.

Display new emails (IMAP + SSL)

Conky has built in support for IMAP accounts but does not support SSL. This can be provided using this script from this forum post. This requires the Perl/CPAN Modules Mail::IMAPClient and IO::Socket::SSL which are in the perl-mail-imapclientAUR and perl-io-socket-ssl packages

Create a file named imap.pl in a location to be read by Conky. In this file, add (with the appropriate changes):

#!/usr/bin/perl

# gimap.pl by gxmsgx
# description: get the count of unread messages on imap

use strict;
use Mail::IMAPClient;
use IO::Socket::SSL;

my $username = 'example.username'; 
my $password = 'password123'; 

my $socket = IO::Socket::SSL->new(
  PeerAddr => 'imap.server',
  PeerPort => 993
 )
 or die "socket(): $@";

my $client = Mail::IMAPClient->new(
  Socket   => $socket,
  User     => $username,
  Password => $password,
 )
 or die "new(): $@";

if ($client->IsAuthenticated()) {
   my $msgct;

   $client->select("INBOX");
   $msgct = $client->unseen_count||'0';
   print "$msgct\n";
}

$client->logout();

Add to ~/.conkyrc:

${execpi 300 ~/.conky/imap.pl} 

or wherever you saved the file.

If you use Gmail you might need to generate an application specific password.

Alternatively, you can use stunnel as shown above: Conky#How to display the number of new emails (Gmail) in Conky

Fix scrolling with UTF-8 multibyte characters

The current version of conky (1.9.0) suffers from a bug (http://sourceforge.net/p/conky/bugs/341/) where scrolling text increments by byte, not by character, resulting in text containing multibyte characters to disappear and reappear while scrolling. A package with a patch fixing this bug can be found in the AUR: conky-utfscrollAUR

 Ring Meters by londonali1010 (2009)

 This script draws percentage meters as rings. It is fully customisable; all options are described in the script.

 IMPORTANT: if you are using the 'cpu' function, it will cause a segmentation fault if it tries to draw a ring straight away. The if statement on line 145 uses a delay to make sure that this does not happen. It calculates the length of the delay by the number of updates since Conky started. Generally, a value of 5s is long enough, so if you update Conky every 1s, use update_num > 5 in that if statement (the default). If you only update Conky every 2s, you should change it to update_num > 3; conversely if you update Conky every 0.5s, you should use update_num > 10. ALSO, if you change your Conky, is it best to use "killall conky; conky" to update it, otherwise the update_num will not be reset and you will get an error.

 To call this script in Conky, use the following (assuming that you save this script to ~/scripts/rings.lua):
         lua_load ~/scripts/rings-v1.2.1.lua
         lua_draw_hook_pre ring_stats
  
 Changelog:
 + v1.2.1 -- Fixed minor bug that caused script to crash if conky_parse() returns a nil value (20.10.2009)
 + v1.2 -- Added option for the ending angle of the rings (07.10.2009)
 + v1.1 -- Added options for the starting angle of the rings, and added the "max" variable, to allow for variables that output a numerical value rather than a percentage (29.09.2009)
 + v1.0 -- Original release (28.09.2009)

A note about symbolic fonts

Many of the more decorated .conkyrc's use the fonts PizzaDude Bullets and Pie Charts for Maps. They are available from the AUR as 'ttf-pizzadude-bullets' and 'ttf-piechartsformaps' respectively, or they can be found and downloaded with a quick search and manually installed using the instructions in Fonts.

Fonts appear smaller than they should

If you notice that your conky fonts appear smaller than they should, or they don't align properly, it could be caused by a default setting in the infinality freetype2 patch. This setting can cause some programs to display fonts at 72 DPI instead of 96 even if the rest of your system is set to 96. If you notice a problem open /etc/fonts/infinality/infinality.conf search for the section on DPI and change 72 to 96.

Universal method to enable true transparency

Transparency is a strange beast in Conky, but there is a way to universally apply true transparency with any environment or window manager by using xcompmgr and transset-df. Install xcompmgr from [extra] and transset-df from [community] with pacman -S xcompmgr transset-df. These packages both have the same 3 dependencies, so this is the lightest method for composition available, for those of you using standalone window managers in order to achieve the leanest setup you can manage (or whatever reason you have :D)

NOTE: This may conflict with any other compositing manager you are already using.

Check xcompmgr documentation to help you decide which compositing options you would like to enable. The following is a common standard command.

$ xcompmgr -c -t-5 -l-5 -r4.2 -o.55 &

Make sure conky is running with conky &. Use transset-df to enable transparency on the Conky window. Set '.5' to any value in the range 0 - 1.

$ transset-df .5 -n Conky

This should give your conky window true transparency. If you get an error like,

$ transset-df .5 -n Conky
No Window matching Conky exists!

Verify that conky is running, and use xprop and click on the conky window to find the name you should pass to transset-df.

$ xprop | grep WM_NAME
WM_NAME(STRING) = "Conky (ArchitectLinux)"

In this case, "Conky" is right, but for you it may be different, so be sure to use your output instead. If ~/.conkyrc has own_window_type panel then this xprop invocation may show now output. Try using any of the following options instead. own_window_type {dock,normal,override,desktop}

Use this in ~/.xinitrc to have transparent conky run when you startx.

xcompmgr -c -t-5 -l-5 -r4.2 -o.55 &
conky -d; sleep 1 && transset-df .5 -n Conky
