ubuntu 256 bit color urxvt (from internet)

Steps used to recompile urxvt with the 256 bit color patch.
$ apt-get source rxvt-unicode
$ sudo apt-get build-dep rxvt-unicode
$ cd rxvt-unicode*
$ patch -p1 < doc/urxvt-8.2-256color.patch
$ sudo dpkg-buildpackage -us -uc
$ sudo dpkg -i rxvt-unicode_9.05-4_i386.deb
$ echo "rxvt-unicode hold" | sudo dpkg --set-selections
in your .Xdefaults file, type: rxvt.termName=xterm, so that most ssh to other machine will support 256 color.

The last step makes sure apt doesn't reinstall the old package the next time you update.

opera keyboard issues

I found that sometime my keyboard didn't respond in opera. I can get this fixed by start a terminal and close it, then my keyboard come back.
But today I found a solution.
It is caused by conflict between it and scim.
So:
sudo apt-get install scim-qtimm
sudo vim /usr/bin/opera

add "export export QT_IM_MODULE=SCIM" at second line.

restart opera and all is fine.

Opera with Chinese font config

First, you need to have YaHei font, which I think can give you best profile when Chinese+English is showing. I even use it as the font in terminal. I think it is better than WenQuanYi.
Methods of installing YaHei is in another post of mine.

1. Tools->Preferences->advanced->fonts; all change to YaHei Consolas Hybrid.
2. type opera:config in address bar, search antialiasing and dismark it.
3. open a terminal, type:
echo 'html,body,*{font-family:"YaHei Consolas Hybrid" !important;}' > ~/.opera/styles/user/user.css
4. restart opera, view->style->user.css.
tools->preferences->general->language->details->encoding to assume...->gb18030
5. restart opera.
You will find the Chinese font is perfect.

Chinese configure in wine

1. add wine-cn source
wget -O- 'http://keyserver.ubuntu.com:11371/pks/lookup?op=get&search=0x84DD336194625C2F' | sudo apt-key add -

echo -e "deb http://ppa.launchpad.net/wine-cn/ppa/ubuntu jaunty main\ndeb-src http://ppa.launchpad.net/wine-cn/ppa/ubuntu jaunty main" | sudo tee /etc/apt/sources.list.d/wine-cn.list

2.
sudo apt-get update
sudo apt-get install wine

3.
If you "Locale" is not zh_CN, MODIFY the command line in ~/.local/share/applications/wine-Programs-XXX.desktop TO env LANG=zh_CN.UTF-8 wine "C:\Program Files\XXX.exe" to provide Chinese support.

Chinese font configuration in ubuntu 9.04

I prefer YaHei font, due to its good mix of Chinese and English
1. Download from http://rs54l33.rapidshare.com/files/34563809/5101584/YaHei.Consolas.1.11b.zip
2. Copy the ttf file to ~/.fonts
3. fc-cache -fv (to refresh the font list)
4. Right click on desktop -> Change Desktop Background -> Fonts. Change all to YaHei ....

Done.
