Thinkpad X24 + Linux で dual head

マルチモニター(Dual Display /dual head)をやってみたくて設定をやってみたが、結構簡単にできた。

OS: Vine linux 3.1CR
PC: Thinkpad X24
LCD : Sony SDM-S204(/Samsung LCD SyncMaster 213T) と TPX24のLCD

Vine linux 3.1ではXineramaが最初から使えるらしく、xorg.confと
dual headsで検索したときの設定を流用するだけで良かった。

具体的には、下のようにxorg.confを書き換えて、Xを立ち上げるだけ。
ノートスクリーンの右横に1600x1200の外部LCDが並ぶ形になり、カーソル
を動かすことで両者が行き来できる。なお、この場合、仮想デスクトップ
サイズが(1024+1600)x1200となるようだ。

なお、この場合、Fn+F7でのon/off/切り替えはできなくなる。
現在、外部LCDにvmware(Windows 2000)、本体LCDにLinuxを出して
作業しているが、非常に快適だ。
