The program 'gnome-settings-daemon' received an X Window System error.

This probably reflects a bug in the program.

The error was 'BadRequest (invalid request code or no such operation)'.

  (Details: serial 107 error_code 1 request_code 151 minor_code 6)

  (Note to programmers: normally, X errors are reported asynchronously;

   that is, you will receive the error a while after causing it.

   To debug your program, run it with the --sync command line

   option to change this behavior. You can then get a meaningful

   backtrace from your debugger if you break on the gdk_x_error() function.)

ERROR: While executing gem ... (Gem::GemNotFoundException)
Could not find rails (> 0) in any repository

$sudo gem sources -a http://gems.rubyforge.org

$sudo gem install rails -y

1. 安裝 bootchart，安裝完成以後，得重開機，讓 bootchart 能獲取必要的資訊。

   $sudo apt-get -y install bootchart

2. 重開機之後，bootchart 會把必要的資訊紀錄在 /var/log/bootchart.tgz。由於 bootchart 所提供的工具是用 Java 程式(/usr/share/bootchart/bootchart.jar)寫的，所以你還得確定有安裝 Java 或是 IKVM，我這邊是使用 ikvm。ikvm 是一個可以利用Mono(Linux 下的 .Net 執行環境)來執行 Java 程式的工具，一般來說，如果你有使用 Tomboy 或是 Beagle 的話，Mono就已經安裝了。

   $sudo apt-get -y install ikvm

3. 執行 bootchart.jar，這會解析 /var/log/bootchart.tgz，然後產生 bootchart.svgz 在當前目錄下。

   $ikvm -jar /usr/share/bootchart/bootchart.jar

4. 有了 bootchart.svgz，該怎麼去看這個圖呢？這邊提供兩種方法：
   • 利用 Firefox：把 bootchart.svgz 以 zcat 解開，再用 Firefox 打開即可。

     $zcat bootchart.svgz > bootchart.svg

   • 用 Inkscape 開啟檔案。

     $sudo apt-get -y install inkscape

sudo aptitude purge `dpkg -l | grep ^r | awk '{print $2}'`

1. 點取選單：應用程式 > 影音 ，執行 DeVeDe。
2. 選取 Video DVD
3. 右邊清單下有"新增"，會跳出另外一個對話盒，你可以從這邊去選取你要加入的影片，設置影片尺寸、縮放、輸出訊號(NTSC、PAL)等等。
4. 加入以後，畫面下方會顯示你使用了多少空間。不過據我的經驗，整個放滿以後製作出來的 DVD ISO 檔才約 2.1G。點取右下角的"下一頁"之後，DeVeDe就會開始進行轉檔與製作 DVD ISO 。
5. 最後再執行GnomeBaker來燒錄產生出來的 ISO檔案即可。

1. 請找到並下載 Kyocera_Mita_KM-3035_en.ppd. (用 Google 找！)
2. 執行系統 > 管理 > 列印
3. 選擇 "新增印表機"，選取"網路印表機"，然後再選取 HP JetDirect，填入 IP 位址，進入下一步
4. 選擇"安裝驅動程式"，然後選到剛剛步驟一所下載的Kyocera_Mita_KM-3035_en.ppd，下一步
5. 指定名稱、說明以後，選擇"套用"即可
