Using a computer without a mouse and a monitor

Can you believe it? It’s not so hard to achive that. We just made it today.

I have been keeping a computer under my desk for nearly a year. The mouse is broken. I think I’ve sold the monitor. I plan to buy a widescreen LCD someday. But today I asked Jack to help me with the book writing things and we don’t have an extra computer. He reminded me that I could use the TV set. Fortunately there is a VGA socket on my TV.

Jack borrowed a VGA cable. I just connected the computer to the TV and booted it hoping everything’s fine.

But there came another problem. Because the screen resolution is too high for the TV there’s nothing showing up on the sceen. I knew what I needed to do is to adjust the resolution, but how?

I pluged in the headphone and looked at the screen of the laptop(It’s David’s laptop and was brought in by Alfred). Firstly logged off the Laptop to the Login screen. Then started pressing the "tab" key several times to see where the cursor moved to. And did the same simultaneously on the keyboard of the previouse computer. And when the box for password is activated, I typed in the password and then "enter".

When I heard the windows login music I waited for a moment for the softwares start with windows. Then I think you know what I did:

"win key" -> "win key"+"d" -> "Menu Key" -> "r" -> "shift"+"tab" -> "right arrow" for several times -> "tab" 3 times -> "left arrow" for many times to make sure the resolution is the lowest -> "alt"+"a" -> "y"

win key (left) & menu key (right)

If you don’t understand those steps just try them out. You’ll get it. That was the exciting moment. The desktop appeared on my TV!

The next problem is that althought most of the operations we do with a mouse can be done with the keyboard, some poor programmers develop softwares that can’t be used without a mouse. Like the IP-COM wireless connection management software. I plugged in the IP-COM USB wireless adapter and installed the driver and application. This application disabled the function of the system to manage the wireless connections. I was forced to use its own application. But the buttons of that application can’t be pressed using the keyboard! What a stupid software!

Now I have to use a mouse but I don’t have one. It occured to me that there’re some options to enable the user to use the keyboard to act like a mouse right after I said "I give up". I remembered that it was something with accessibility in the Control Panel. So I was just like "Check it out!"

"win key" -> "c" -> "tab" for several times to select "Accessibility Options" -> "enter" (-> if you are in Category View you need to press "tab" for a few more times and select "Accessibility Options" under "or pick a Control Panel icon" then "enter") -> "shift"+"tab" -> "right arrow" for three times to select "Mouse" -> "tab" -> "space" to check the checkbox before "Use MouseKeys" -> "enter"

OK, now you can use "num lock" key to turn on or off the MouseKeys function. How to use it? You can use your numeric keypad as a mouse.

You can use 1, 2, 3, 4, 6, 7, 8, 9 to move the pointer to those eight direcitons. Pressing "5" on numeric keypad is equal to press the left button of the mouse (click). Pressing "+" on numeric keypad is equal to press the right button of the mouse (right click). Amazing, huh?

But the pointer seems to be moving so slowly. You can open the "Accessibility Options" again. On the "Mouse" tab click "settings". Now you can adjust the speed of the pointer and I like to check "Hold down Ctrl to speed up and Shift to slow down".

That’s it. Now we made it. To use a computer without a monitor and a mouse.

Using SCIM in English interface

惭愧啊,在ubuntu里搞定中文输入法竟然花费了近一天的时间。其实如果是把语言设置为中文的话也没那么多麻烦。只是我个人偏好英语的界面(再说ubuntu的中文界面下字体很难看),问题就出在这里了。只要切换到英语的界面,scim就不管用了。在网上看到了解决办法:

先用这句来安装im-switch和scim

sudo apt-get install im-switch scim

然后用下面两句来进行设置:

sudo im-switch -s scim -z all_ALL
im-switch -s scim -z all_ALL

结果我的问题就出在这里了,其实有错误提示,但我一直没有看到,提示内容是:

No system wide default defined just for locale en_US .
Use "all_ALL" quasi-locale and set IM.
update-alternatives: Cannot find alternative `/etc/X11/xinit/xinput.d/scim’.

没注意这里的提示我还到处找别的原因,又试着装了fcitx,接着卸了又装,装了又卸,还手动修改/usr/lib/gtk-2.0/2.10.0/immodule-files.d/libgtk2.0-0.immodules,都不起作用。直到看到错误提示,才想起,原来是要update-alternatives。用下面这句:

update-alternatives –install /etc/X11/xinit/xinput.d/all_ALL xinput-all_ALL /etc/X11/xinit/xinput.d/scim 30

完了之后再用上面那两句来设置,没有错误提示了,重启就OK了。

Ubuntu (pronounced "oo-boon-too")

Ubuntu is a South African ethical ideology focusing on people’s allegiances and relations with each other. The word comes from the Zulu and Xhosa languages. Ubuntu (pronounced "oo-boon-too") is seen as a traditional African concept, is regarded as one of the founding principles of the new republic of South Africaband is connected to the idea of an African Renaissance.

A rough translation of the principle of Ubuntu is "humanity towards others". Another translation could be: "the belief in a universal bond of sharing that connects all humanity".

         "A person with ubuntu is open and available to others, affirming of others, does not feel threatened that others are able and good, for he or she has a proper self-assurance that comes from knowing that he or she belongs in a greater whole and is diminished when others are humiliated or diminished, when others are tortured or oppressed."

Archbishop Desmond Tutu

As a platform based on Linux, the Ubuntu operating system brings the spirit of ubuntu to the software world.
