色々思うところあってs30をsiduxにしました．

例によって，LiveCDは反転したような画面で起動します．
ここで諦めないで，なんとかControl Center->display検索->displayで解像度かリフレッシュを60Hzとかに変えてApply!
Ctrl+Alt+BackSpaceして，X再起動したら普通な画面になってるはず，うちのはなった．

後は普通にインストール．死ぬほど楽．
再起動後，grubのbootオプションにsingleを書いて，設定したrootのパスワードでlogin.
xorg.confがぐちゃぐちゃなので，以下のものと差し替えで完了．後は日本語関係をインストール中

s30のxorg.conf置いておきますね．多分これで普通に表示できる．
