雙螢幕 + Xinerama

關鍵字:

繼 linkname:[雙螢幕 - Multihead Configuration for Xorg] http://heaven.branda.to/~thinker/GinGin_CGI.py/show_id_doc/242 後， Panasonic R5 已經可以支援兩個 screen 。但這是兩個獨立的 screen ，有各獨立的 window ， window 也無法互跨或轉移。

如果想組成電視牆，那該怎麼辨？必需讓一個視窗能跨數個 screen ，個別顯示 window 的部分畫面。 linkname:Xinerama http://en.wikipedia.org/wiki/Xinerama 就是這樣的功能，只需在 xorg.conf 加入一個 section "ServerFlags" 就可以啟動 Xinerama 。

這個我以前玩過，就是 notebook 本身 lcd 加上外接的螢幕，形成一個超寬的桌面，但不記得用到了 serverflag...？
