Ubuntu 12.04 lts 32bit LXDE 一定時間無操作が続いた時に自動でサスペンドする方法

Ubuntu 12.04 LTS 32bitのデスクトップ環境LXDEは自動でサスペンドに移行させる機能がもともとない。そこで以下の操作を行う。

-timeの後の数字は、サスペンドが実行されるまでの時間を表す。
下の例では、無操作が1分続いた後にサスペンドが実行される
 
sudo leafpad /etc/xdg/lxsession/LXDE/autostart

@xscreensaver -no-splash
@lxpanel --profile LXDE
@pcmanfm --desktop --profile LXDE
@/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1
xautolock -time 1 -locker "xscreensaver-command --lock && dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Suspend"

pppoe接続 (有線) をやめて、無線LAN(wifi)でネットをする場合

sudo gedit /etc/network/interfaces
auto lo
iface lo inet loopback

だけにしてあとはすべてコメントアウト


sudo gedit /etc/NetworkManager/NetworkManager.conf
[ifupdown]
managed=true

ubuntu 12.04 lts 32bit pppoeでネットにつなぐ方法

sudo pppoeconf



sudo gedit /etc/network/interfaces

auto lo
iface lo inet loopback


auto dsl-provider
iface dsl-provider inet ppp
pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
provider dsl-provider

auto eth0
iface eth0 inet manual



sudo gedit /etc/NetworkManager/NetworkManager.conf

デフォルトのブラウザを変更する方法 ubuntu 12.04 lts 32bit JWM (joe's window manager)

firefoxの更新などで、デフォルトのブラウザがchromiumなどになってしまう場合、次のコマンドで元に戻すことができる

 sudo update-alternatives --config x-www-browser

alternative x-www-browser (/usr/bin/x-www-browser を提供) には 2 個の選択肢があります。

  選択肢    パス                     優先度  状態
------------------------------------------------------------
* 0            /usr/bin/chromium-browser   40        自動モード
  1            /usr/bin/chromium-browser   40        手動モード
  2            /usr/bin/firefox            40        手動モード

現在の選択 [*] を保持するには Enter、さもなければ選択肢の番号のキーを押してください: 2
update-alternatives: /usr/bin/x-www-browser (x-www-browser) を提供するために 手動モード で /usr/bin/firefox を使います。

ルータがないけれどインターネットに繋ぎたい場合 ubuntu 12.04 lts 32bit

 ADSL モデムあるいは光回線終端装置のみしかない場合、以下のコマンドを実行してインターネット接続を行う。

sudo pｐpoeconf
