デュアルディスプレイ設定

デュアルディスプレイでないと作業効率が落ちるので設定。


/etc/X11/xorg.confを書き換えてやれば良いのですが手順としては

  1. /etc/X11/xorg.conf を ~/xorg.confなどにコピーしておく。(うまくいかない場合は戻せるように)
  2. /etc/X11/xorg.conf を書き換える
  3. ログアウトする
  4. ログイン画面で ctrl-alt-backspaceで GDM を再起動
  5. ここでうまくいっていればログイン画面が表示される
  6. うまくいかない場合はtextのCUIになるので、xorg.confをてきとうに修正。
  7. /etc/init.d/gdm restartで再起動
  8. これでうまくいけばログイン画面が表示されます。
  9. xorg.conf修正、GDMの再起動を繰り返していきます。
  10. どうしてもうまくいかない場合はあきらめて、~/xorg.confをcp して元に戻します。


僕の xorg.confは以下の通りです。
