gOS Rocket - Trend of the future gOS Rocket——未来操作系统的趋势

Mon, 21 Jan 2008 16:58:22 GMT

gOS Rocket is a brand new Linux Distribution based on the popular Ubuntu 7.10. Apart from the fact that it use Enlightenment 17, instead of Gnome or KDE in Ubuntu, as its default window manager, the most exciting feature of it lies in the integration of Google Web Applications. The following review is based on Virtual Box 1.5.4.

gOS Rocket 是一个基于目前大受欢迎的Ubuntu 7.10的全新Linux发行版本。除了使用Enlightenment 17作为默认的窗口管理器之外（而不是Ubuntu中默认的Gnome或者KDE），其最激动人心的特点在于对Google网络服务的大力整合。以下的评测基于虚拟机软件Virtual Box 1.5.4。

We can see that the interface is very neat, with date and time shown in the bottom-right corner, which is exactly like Ubuntu 7.10. Also we can notice the default Enlightenment window manager.

登录界面十分简洁，日期时间在右下角的显示与Ubuntu 7.10 如出一辙。注意观察可以发现默认的Enlightenment窗口管理器。

Startup desktop 起始桌面

We have to admit that the dock at the bottom is very similar to the one in Mac OSX. From left to right, the icons represent: Firefox, Gmail, Gtalk, Google Calendar, Google Doc, Google Reader, Google Map, Google News, Google Finance, Google Product Search, gBooth(Bad Link, function unknown), Youtube, Blogger, Facebook, Wikipedia, Meebo(Multi protocol online IM service, details shown later), Skype, Xine Movie Player, Rythmbox (Music player), Box.net (online storage service) and FAQly (official gOS technical support community). We can see that more than half of them are services provided by Google.

The Google bar in the middle is actually a short cut to Google web search.

必须承认桌面下方的启动栏和Mac OSX做的很类似。这些图标其实是（从左到右），火狐, Gmail（电邮）, Gtalk（聊天）, Google 日历, Google 文件, Google 阅读器, Google 地图, Google 新闻, Google 财经, Google 产品搜索, gBooth(无效链接，功能不明), Youtube（视频）, Blogger（博客）, Facebook（校友录）, Wikipedia（维基）, Meebo(多功能在线聊天工具), Skype（聊天）, Xine 电影播放器, Rythmbox (音乐播放器), Box.net (在线存储) and FAQly (官方技术支持社区)。可以发现半数以上的服务是由Google提供。

中间的Google栏指向Google搜索。

Meebo（多功能在线聊天）

Box.net（在线存储）

Internet Application List 网络相关应用程序列表

Like Ubuntu, gOS also use Synaptic Package Manager. My gOS is like My Computer in Windows. The directory structure is also very similar to Ubuntu 7.10, except the gos folder, as shown below:

类似于Ubuntu，gOS也采用了Synaptic来管理安装包。My gOS则类似于Windows里面的我的电脑。文件构成和Ubuntu 7.10十分类似，只是多了一个叫gos的文件夹，如下

The gos folder 文件夹gos

User friendly setting interface 非常直观的设置界面

Wallpaper, Theme & Shelf settings 墙纸，主题和架子的设置

Brief summary 简短总评

Pros: Slim and fast, user-friendly, Online apps

优点：简洁高效，直观友好，在线服务

Cons: Bugs, Not for geek, Not enough offline support (will be improved by Google gear)

缺点：程序错误，不够专业，离线支持较平庸（Google gear将会带来改进）

Although gOS is not officially released by Google, it still can show Google's ambition and capability to enter the Desktop OS market. As the fast development of the Internet, people will more and more rely on online service for both personal and business needs. There are plenty of reasons for us to believe, the integration of online and offline applications will be the future trend for operating systems.

虽然gOS并不是Google官方推出的操作系统，它仍能显示出Google进军桌面操作系统市场的能力和决心。随着互联网的飞速发展，不管是个人还是商业都必将越来越依赖于在线服务。我们有足够的理由相信，在线和离线服务的整合必将是未来操作系统的趋势。

[HOWTO]解决Ubuntu 7.10龟速启动问题 How to eliminate extremely slow boot up for Ubuntu 7.10

Sun, 04 Nov 2007 13:36:36 GMT

全新安装Ubuntu 7.10后启动速度变得异常缓慢
多方查找后发现是File System Check(Fsck)的问题
解决方法如下：
1. 在Terminal中输入：sudo gedit /etc/fstab
2. 找到如下的文字：
# /dev/sda1
UUID=6E50BE5450BE22AF /media/sda1 ntfs defaults,umask=007,gid=46    0     1
3. 把最后的1改成0
结果如下
# /dev/sda1
UUID=6E50BE5450BE22AF /media/sda1 ntfs defaults,umask=007,gid=46    0    0
4. 找出所有的中间是 NTFS 或者Vfat或者FAT32之类Windows的磁盘系统, 把最后的数字都改成0。
5. 存盘重启。
6. 其实问题就出在 FSCK 默认检查所有磁盘分区，而作为Unix/Linux专用的磁盘工具检测Windows 分区会出错从而拖慢启动。

再修改Grub的设置，方法如下：
1. 在Terminal中输入：sudo gedit /boot/grub/menu.lst
2. 找到如下行：
kernel     /boot/........... ro quiet splash
3. 把splash改为nosplash，结果如下：
kernel     /boot/........... ro quiet nosplash
4. 存盘退出。

After fresh installed Ubuntu 7.10 I suffered from extremely slow boot up
Finally I found that it was because of File System Check(Fsck) utility
The resolutions are as follows:

1. Type in Terminal：sudo gedit /etc/fstab
2. Find the similar lines as below
# /dev/sda1
UUID=6E50BE5450BE22AF /media/sda1 ntfs defaults,umask=007,gid=46    0     1
3. Change the last 1 to 0, so the result looks like:
# /dev/sda1
UUID=6E50BE5450BE22AF /media/sda1 ntfs defaults,umask=007,gid=46    0    0
4. Find all the similar cases( lines containing NTFS, VFAT or FAT32, so called windows file systems) and change the last 1 to 0.
5. Save and reboot.
6. In conclusion, the problem lies in the fact that by default FSCK checks all the partitions for consistency, but as a utility under Unix/Linux, checking those windows partitions will cause problems and thus make the boot up extremely slow.

Then modify Grub configurations:
1. Type in Terminal: sudo gedit /boot/grub/menu.lst
2. Find the similar line as follows:
kernel     /boot/........... ro quiet splash
3. Change "splash" to "nosplash"
4. Save and exit.

How to get Ati+Xgl+Beryl to work stable in Ubuntu 7.04

Tue, 24 Apr 2007 22:11:37 GMT

Been trying out many methods online but none of them work perfect.
The open source ati driver+beryl will cause system freeze at random and only mouse can move
The open source ati driver didn't support xgl
The ati restricted driver coming with ubuntu didn't support Composite (ubuntu desktop effect)
The ati restricted driver coming with ubuntu didn't support beryl that comes with ubuntu
Xgl didn't support the beryl that comes with ubuntu

So the following method will work
Tested base on Thinkpad t43, with X300 graphic card, Ubuntu 7.04, Feisty Fawn

1. Install ATI restricted driver with Synaptic

2. Edit xorg.conf by
sudo gedit /etc/X11/xorg.conf
Find the line with
Driver "ati"
or
Driver "radeon"
or
Driver "vesa"
Change the line to
Driver "fglrx"

3. Disable Composite ( the default desktop effect coming along with Ubuntu 7) by
sudo gedit /etc/X11/xorg.conf
Add the following lines to anywhere out of other sections
Section "Extensions"
Option "Composite" "false"
EndSection

4. Reboot and test with fglrxinfo in terminal, the output should be something like:
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: MOBILITY RADEON X300
OpenGL version string: 2.0.6334 (8.34.8)

5. Add beryl repos
In System\Administration, select Software sources\Third-Party Software, click Add and type:
deb http://ubuntu.beryl-project.org/ feisty main
Then download this repo key file: http://ubuntu.beryl-project.org/root@lupine.me.uk.gpg
In Authentication, click Import key file and select the file you just downloaded.

6. Install Xgl and Beryl
In Synaptic, search for xserver-xgl, beryl-ubuntu, beryl-manager, emerald-themes and do installation.

7. Let system prefer beryl-project packages
Alt+F2, type gksudo gedit /etc/apt/preferences and add the following content

Package: *
Pin: release o=lupine
Pin-Priority: 1000

8. Downgrade beryl-core file
	In Synaptic, reload, search for beryl-core, click "package" in menu and choose "force version"
	Choose 0.2.0-0beryl1 and install

9. Add a Xgl login session
	Run the following in terminal to create the file:
		sudo gedit /usr/local/bin/startxgl.sh
	Paste in the following content
#!/bin/sh
Xgl :1 -fullscreen -ac -accel xv:pbuffer -accel glx:pbuffer &
DISPLAY=:1
cookie="$(xauth -i nextract - :0 | cut -d ' ' -f 9)"
xauth -i add :1 . "$cookie"
exec dbus-launch --exit-with-session gnome-session

10. Create xgl login session entry
	Create a new directory using: 
		sudo mkdir -p /etc/X11/sessions
	Create the file with 
		sudo gedit /etc/X11/sessions/xgl.desktop
	Paste in the following content

[Desktop Entry]
Encoding=UTF-8
Name=Xgl
Exec=/usr/local/bin/startxgl.sh
Icon=
Type=Application

11. Reboot
	On login window, remember to change session to Xgl. After login, run beryl-manager. If
everything is ok you may add beryl-manager to startup session and make xgl your default login
session. 


* This guide is basically based on the following 2 guides since neither worked but when combined ok

Hail for Ubuntu 7.04 !!!

Fri, 20 Apr 2007 11:34:43 GMT

Been playing with the newly released Ubuntu 7.04, Feisty Fawn for the past 2 days
Extremely impressed by its user friendly interface and ease of software management system
Also the wide availability of customization.
Now I have changed the whole interface just like Mac OSX in the following aspects:
-Boot and shut down Screen
-Login interface
-Window Border (The close/minimize/restore buttons are finally on the LHS !!)
-Icons and wall paper
-Visual effect
-Mouse Cursor
-Dock
-Font
-Menu buttons
-Firefox Theme

And I have to admit that the imitation effect is even better than FlyakiteOSX in Windows!
Maybe next I will work on system sound and menu bar and most important...Chinese input

In the customization process I've read many tutorials and tried many approaches and some of them didn't work... Anyway, special thanks to these websites:

Well actually I haven't tried many other linux distros
Only 3 by now, Fedora, Opensuse, Ubuntu
And Ubuntu is the best among these 3 in user accessibility and community support
Also I assert that it provide a far better user experience than Windows Vista in appearance and performance and many more aspects

Those who feel tired about your every-day-the-same Windows interface should really have a try of the elegant Ubuntu
For it provide you with a Desktop CD with which you can boot your machine and try out all the headlight features of the OS without the trouble of installation
I mean
What you need to do is to download the iso and burn it into a CD (only 698 MB) and use it to boot
After trying it out I am sure you can't deny installing it and making your machine a dual boot one

Attached is the screenshot of my current desktop
