[メモ](らずぱい) conkyでシステムモニター

More than 1 year has passed since last update.

概要

  • Linuxのデスクトップにシステムステータスを表示するやつ...って、よく忘れるので、メモ。
  • conkyっていう名前も忘れるし(Linux デスクトップ ステータス 表示とかで検索)、設定もその都度、調べるし...ここに書いておけば自分の記事検索すればいいしね。
  • 設定は、 conky settings raspberry piというキーワードでググって出てきた、Jeffさん?のConky for the Raspberry Piのところの設定をベースに、4つのCPU対応にしただけ。

環境

  • Raspberry Pi 2
  • Raspbian: 2017-02-16-raspbian-jessie.img

    pi@raspberrypi:~ $ uname -a
    Linux raspberrypi 4.4.48-v7+ #964 SMP Mon Feb 13 16:57:51 GMT 2017 armv7l GNU/Linux
    
  • 縦720ピクセル向け?

手順

  1. いつもの(img焼いて、パッケージアップデート)
  2. conkyインストール
    sudo apt-get install conky-all
  3. 設定 : ${HOME}/.conkyrc

    /home/pi/.conkyrc

  4. 自動起動設定: ${HOME}/.config/lxsession/LXDE-pi/autostart

    こぴぺで、autostartに追記
    grep conky ${HOME}/.config/lxsession/LXDE-pi/autostart > /dev/null|| echo '@conky -p 15' >> ${HOME}/.config/lxsession/LXDE-pi/autostart
    
    ${HOME}/.config/lxsession/LXDE-pi/autostart(編集例)
    @lxpanel --profile LXDE-pi
    @pcmanfm --desktop --profile LXDE-pi
    @xscreensaver -no-splash
    @point-rpi
    @conky -p 15
    
    • -p オプションで、ん秒後にスタートを指定

      -p | --pause= SECONDS
            Time to pause before actually starting Conky
      

その他

  • conky -c ore_no_setting
    で、設定ファイルを指定。
  • ク~ルな設定があったら、コメントへ。
