[游手] HP mini 2133 Ubuntu 9.04 VGA 設定

明明是生病了，沒有力氣做什麼正事，卻撐著發燒的身體，把裝在 HP mini 2133 裡的 Ubuntu Linux 9.04 的 VGA 設定和 3D 加速搞出來了！(呀呼～)

故事是這麼開始的…

HP mini 2133 在全世界有許多國家販售，但是有在玩 Linux 的，或是在電子製造業待過的都會知道，就算是「同一型號」的硬體，只要生產地不同、販賣地不同，甚至只是生產日期的不同，都可能會有不一樣的晶片元件在裡面。

所以，雖然 HP mini 2133 這款小筆電上採用的雖然都是 VIA 的處理器和繪圖晶片，但是還是有些細節不太一樣。


好玩的部份來了！我買的 HP mini 2133 是搭售 Suse Linux 的，買回來後我再改裝成 Ubuntu Linux，但是不管是哪一種 Linux，在購買的那個時候 VIA 方面卻「還沒寫好繪圖晶片給 Linux 用的 3D 驅動程式！」也就是說，我買了一部極速 400 km/hr 的超級跑車，但是「耐得住這個速度的輪子還沒發明出來！」 (-_-)"

不過呢，Open Source 開放原始碼的社群裡的各家高手們可沒有閒著，馬上就開始著手用逆向工程的方式寫出了驅動程式。但是…客倌啊…有一好，沒兩好，世間事就是這麼樣地難以一兼二顧啊！

開放原始碼的高手們寫出了 OpenChrome 這套繪圖晶片的驅動程式，可以讓 HP mini 2133 上的 VGA 輸出埠正常地使用。只要接上外接螢幕的線，不管是寬螢幕電視、投影機還是桌上的 LCD/CRT 都能馬上辨識出來，進入 Clone 模式。這樣拿來做簡報，真是再好不過了！

相較之下， 3D 加速的部份，因為涉及晶片本身的規格內容，而 VIA 方面又不願意公開，所以大夥兒都還在繼續努力做著逆向工程…

另一方面呢， VIA 經過近兩年的努力，終於寫出了自家產品繪圖晶片給 Linux 用的 3D 加速驅動程式， 叫做 VIA Chrome 9 驅動程式…但是搞笑的是…如果裝上這個驅動程式的話， 3D 加速的部份是正常了，但是卻沒辦法做 VGA 的輸出…也就是說，所有的外接顯示器都不能用！媽呀…如果不能外接做簡報，那要小筆電幹嘛？

所以…簡單地說，對一個 HP mini 2133 的使用者來說，你究竟應該要：
1. 安裝 OpenChrome：可以外接螢幕做簡報，但是沒有 3D 加速功能！
2. 安裝 VIA Chrome 9: 不能外接螢幕做簡報，但是有 3D 加速功能！

做為一個使用者的我，我想要可以外接螢幕，不然我手上這個小小的螢幕才對角線 8 吋…整體看來，比一個披薩還小啊…

我也想要有 3D 加速！因為我最常用的 Linux 功能就是 Compiz 的「多重桌面(影片)」的功能 (就是影片中像是一個大方塊，可以轉來轉去換面的功能。每一面都是一個新的桌面)！我可以方便地在閱讀或是做整理的時候，切換桌面，在不同的主題或是文件圖表、Paper 等等之間遊走、比較。

而且這樣的加速功能並不需要很新的硬體哦！我的桌機已經堂堂邁入十歲了，跑起上面的 Compiz 3D 特效，和影片裡一樣順哩！

如果我能有外接螢幕的功能，也能有 3D 加速的功能，那就可以在簡報的時候同時帶著大家一起比較兩個、甚至更多不同的東西之間的異同了！這絕對遠比在畫面下方那細細的一條「工具列」上切來切去地在不同程式間切換，來得有效率多了！

經過三個禮拜的研究，我得到這個小小的結論：同時擁有 3D 加速和 VGA-out 的功能，應該是可行的。如果能讓 VIA 的 Chrome 9 負責 3D 加速的部份，然後讓 VGA-out 的功能在 xorg.conf 檔中設定好，我看不出任何理由做不出來！(當然，也可能是因為我很遜，所以看不出來！)

--- 廢話分格線；以上都是廢話 ---

照著我的思緒，我先在 Ubuntu Linux 9.04 (Jaunty) 版中安裝的 VIA Chrome 9 的驅動程式：

1. 打開終端機，輸入：
sudo apt-get install linux-headers-generic
2. 接著用 wget 把驅動程式抓回來：
wget http://www.viaarena.com/Driver/5.74.33.86a-u904-50937.tgz
3. 解開抓回來的驅動程式：
tar -xvvf 5.74.33.86a-u904-50937.tgz
4. 切換工作目錄來編譯驅動程式：
cd 5.74.33.86a-u904-50937/DRM_Code/chrome9_2.6.27_28/
5. 編譯：
make
6. 把編好的 .ko 檔移到安裝程式的 bin 目錄：
cp via_chrome9.ko ../../bin
7. 切換工作目錄，準備安裝：
cd ../../
8. 安裝驅動程式：
sudo ./vinstall
9. 把 VIA 的驅動程式加入 Compiz 的許可名單 (whitelist) 裡，這麼一來才能正常啟動 Compiz 的特效：
sudo gedit /usr/bin/compiz
找到下面這一段 whitelist, 然後把 via 加進去 (紅字部份)
# Driver whitelist
WHITELIST="nvidia intel ati radeon i810 via"
到這裡，算是裝好 VIA 的 Chrome 9 驅動程式了。這時候已經可以從 [系統] > [偏好設定] > [外觀] > [特效] 這裡去啟用 Compiz 的效果了。

接著我們繼續調整 xorg.conf 檔。

10. 先把目前的 xorg.conf 檔做個備份，以免玩壞了，還有東西可以補救：
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
11. 我拿國外 luvit 改出來的 xorg.conf 檔，自己再做了點修正 (共三個地方，主要是把解析度從 1024x600 改成 1024x768)，luvit 和其他的外國的 HP 2133 使用者都說這個檔案可以直接使用，但是我試用後，發現解析度不太對勁兒。可能是我之前說的型號一樣，但是裡面的晶片元件不太一樣的緣故吧。

檔案內容如下：

請把上面的設定 copy 回去，另存成 xorg.conf.luvit.768 這樣的檔案在你的桌面上。然後在終端機裡鍵入以下指令，把 xorg.conf 檔代換成上述內容：
sudo cp ~/Desktop/xorg.conf.luvit.768 /etc/X11/xorg.conf
接著登出、再登入一次，讓 Gnome 去讀新的 xorg.conf 就有 VGA-out 了！

至於你的 Compiz 要開啟什麼樣的功能，就超過這篇要講的範圍了。不過，看到投影機在牆面上投射出來，巨大的方塊旋轉畫面時…有一種被震憾到的感動啊！
