Python Gtk+的问题

Question

我不能确定我在我的Lucid盒子上做了什么更新，但现在我得到：

Python 2.6.5 (r265:79063, Apr 16 2010, 13:09:56) 
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gtk
/usr/lib/pymodules/python2.6/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display
  warnings.warn(str(e), _gtk.Warning)
>>> 

有什么提示吗？

更新：

通过完全重新安装X，我设法摆脱了这个问题：

sudo apt-get remove --purge xserver-xorg

sudo apt-get install xserver-xorg

sudo dpkg-reconfigure xserver-xorg

希望这对某些人有帮助！
