nvidia,fglrx以外のドライバ向けのX Window Systemの明るさとガンマのGUI調整ツールを作成
「X Window Systemでnvidia,fglrx以外のドライバを用いた環境における明るさとガンマの調整について(ページ2/3)」「X Window Systemでnvidia,fglrx以外のドライバを用いた環境における明るさとガンマの調整について(ページ3/3)」で作成した、nvidia,fglrx以外のドライバ向けの明るさとガンマの調整ツールのGUI版を作成した。
左側に色曲線,右側に操作のGUI部品を配置しており、いずれかの値を変更するとその場で画面上に反映され、同時に設定の自動キャンセルのカウントダウン(10秒)が開始される。
カウントダウンが始まると「適用」ボタンが押せるようになり、カウントが0になるまでに「適用」を押さないとカウントダウン終了のタイミングで自動的に変更前の値に戻る。
コードはPython(GUIにはPyGTK)を使用しており、動作には
- バージョン2.6/2.7系のいずれかのPython
- PyGTK(PyCairo含む)のバージョン2系
- PyGObject
が必要。

(2011/5/5)ディスプレイが開けなかった場合の処理を修正
libXxf86vm上の処理が失敗すると例外を発生(送出)するようにしているが、今回はlibXxf86vm上の処理が失敗することは想定しておらず、GUIのコード側では捕捉するようにはしていない。
これをもとに、メッセージの国際化や内部処理の改善をしたものをパッケージとして近い内に公開する予定。
使用したバージョン:
- Python 2.6.6, 2.7.1
- PyGTK 2.21.0, 2.22.0
