心優しい先生方のアドバイスを頂きました。ちなみに今、UbuntuからFireFoxでの書き込みです。
アプリケー ションからアクセサリ、そこから
GNOME端末をひらき
sudo gedit/etc/X11/xorg.conf
と入力して編集してみては?
アプリケーション→システムツール→ルート端末を選択すると「GNOME端末」が出て来た。なるほど…これがいわゆるコマンドライン入力画面なのか…と感慨深げに眺める。
sudo gedit /etc/X11/xorg.confと入力したつもりがスペルミスがあった模様で、「なんたらnot Found」と出て来た。スペルの大文字小文字、スペースには要注意が必要だ。何回も見直し入力、リターンを押すと出ました!Xorg.conf!先生ありがとう!ちなみに内容は下記の通り。
# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

多分"1280x1024" "1024x768" "800x600" "720x400" "640x480"の頭に"1280×768"を加えればイイんだろう。6行分書き加えて保存した。ワクワクしながら再起動!の結果!何も変化無し…システム→設定→画面の解像度を開いても、解像度の選択は以前のまま……ん〜〜何が違う?そう言えばアプリケーション→システムツールの中に「GNOME端末」ともう一つ、「コンソール」ってのがあった。見た目は同じコマンドライン入力画面だ。コレを開き試しに
sudo gedit/etc/X11/xorg.confと入力してみた。…GNOME端末からコマンド入力した時と全く同じxorg.confが出て来た。しかも中の解像度の行にはちゃんと1280×768が追加されている。ん〜〜わからん(笑
きっと何かが違うはず。今夜も寝るのは朝になる予感…
