DrRacket 图标不起作用？

Question 1

这是我第一次在线帮助别人。我刚刚自己安装了它。你可能想直接从他们的网站下载它http://racket-lang.org/。然后我选择了Linux x86_64（Debian squeeze版本。它有一个.sh文件扩展名。右键单击下载的文件并转到其属性。单击权限选项卡，然后单击允许以程序形式执行文件。然后双击或右键单击并选择在终端中运行。按照那里的说明进行安装。

Question 2

我可以通过以下步骤使 DrRacket 正常工作：

下载适用于 Debian Squeeze 的 DrRacket Linux 64 位版本这里（笔记：当 DrRacket 新版本发布时，此 URL 将会更改；请访问http://racket-lang.org以确保您获取的是最新版本）

在我的案例中，文件名为racket-5.3-bin-x86_64-linux-debian-squeeze.sh

然后我启动了以下终端会话：

user@computer:~$ cd Downloads
user@computer:~/Downloads$ chmod +x racket-5.3-bin-x86_64-linux-debian-squeeze.sh                
user@computer:~/Downloads$ sudo bash
[sudo] password for user:
root@computer:/home/user/Downloads# ./racket-5.3-bin-x86_64-linux-debian-squeeze.sh 
This program will extract and install Racket v5.3.

Note: the required diskspace for this installation is 285M.

Do you want a Unix-style distribution?
  In this distribution mode files go into different directories according
  to Unix conventions.  A "racket-uninstall" script will be generated
  to be used when you want to remove the installation.  If you say 'no',
  the whole Racket directory is kept in a single installation directory
  (movable and erasable), possibly with external links into it -- this is
  often more convenient, especially if you want to install multiple
  versions or keep it in your home directory.
Enter yes/no (default: no) > no

Where do you want to install the "racket" directory tree?
  1 - /usr/racket [default]
  2 - /usr/local/racket
  3 - ~/racket (/root/racket)
  4 - ./racket (here)
  Or enter a different "racket" directory to install in.
> 2

Checking the integrity of the binary archive... ok.
Unpacking into "/usr/local/racket" (Ctrl+C to abort)...
Done.

If you want to install new system links within the "bin" and
  "man" subdirectories of a common directory prefix (for example,
  "/usr/local") then enter the prefix of an existing directory
  that you want to use.  This might overwrite existing symlinks,
  but not files.
(default: skip links) > /usr
Installing links in "/usr/bin"...
  drracket, gracket, gracket-text, mred, mred-text, mzc, mzpp, mzscheme, mztext, pdf-slatex, planet, plt-games, plt-help, plt-r5rs, plt-r6rs, plt-web-server, racket, raco, scribble, setup-plt, slatex, slideshow, swindle
  done.
Installing links in "/usr/share/man/man1"...
  drracket.1, gracket.1, mred.1, mzc.1, mzscheme.1, plt-help.1, racket.1, raco.1, setup-plt.1
  done.

Installation complete.

注意我对安装程序所提问题的选择/回答。您可以按照我的示例尝试相同的回答，但它们并不是唯一可能的回答；您可以稍微试验一下。

完成这些之后，我只需以普通用户的身份从$提示符下运行以下命令（因此，exit如果您仍处于 root ( #) 提示符下，请运行）：

drracket

显示的 GUI。

我使用的是 Ubuntu 12.04 64 位。不确定您遇到了什么问题，因为它对我来说没问题。
