temporarily changing language for bash output

One may want to temporarily change language for bash'es output some time (like me, reporting bug), and the output language is different from the main locale configuration. Then just prefix `LC_ALL=C' to a command to change to English, e.g.:

# LC_ALL=C aptitude full-upgrade

禁用gnome终端中的M-F激活文件菜单

默认gnome终端中激活文件菜单的快捷键是Alt-F，跟M-F冲突，又无法改变，可以这样设置：不显示主菜单，同是允许菜单快捷方式（编辑>键盘快捷键>启用所有键盘访问键）。

Install Mouse Cursor Theme on GNOME

I also heart that there was one entry in 'Desktop - Preference - Mouse' which could select the X11 mouse theme to be apply for the gnome, but I can not fine such entry at least on Debian, etch.

I find a way to solve the cursor installation problem.

1. After extracting the cursor theme package, place the theme folder under directory ~/.icons. The directory looks like '~/.icons/my_cursor/cursors'.
2. Open gconf-editor and set key '/desktop/gnome/peripherals/mouse/cursor_theme' to the name of the new cursor theme (e.g. my_cursor).
3. If you use another window manager or desktop environment rather than gnome, you need append a line like this in file ~/.Xdefaults:

   Xcursor.theme:THEME_NAME

4. (Optional) the steps mentioned above is used for specific user, and for GDM greeter, you should place the cursor folder under /usr/share/icons/, and then edit the /usr/share/icons/default/index.theme like:

   [Icon Theme]
   Inherits = my_cursor

   'my_cursor' is the cursor theme's folder name under /usr/share/icons. Note: at present, not all cursor themes can be configured successfully in this step. Some cursor themes may make a GDM greeter program crash.
