问题：
在ubuntu 11.10下，利用gvim打开文件时不出错，但是关闭文件时总要出现6、7行的错误提示如下：
(gvim:28478): Gdk-WARNING **: Using Cairo rendering requires the drawable argument to have a specified colormap. All windows have a colormap, however, pixmaps only have colormap by default if they were created with a non-NULL window argument. Otherwise a colormap must be set on them with gdk_drawable_set_colormap (gvim:28478): Gdk-CRITICAL **: IA__gdk_cairo_region: assertion `region != NULL' failed (gvim:28478): Gdk-CRITICAL **: IA__gdk_cairo_region: assertion `region != NULL' failed如果打开的文件不是一个而是N个，那么就会有N次上述错误提示。
真实让人看了很心烦啊。
解决办法：
放狗搜，说是这样的原因：
由于fcitx-frontend-gtk2和gvim冲突造成的错误，可以通过sudo
apt-get remove fcitx-frontend-gtk2解决。
dingq@u1110-120628:/nfsroot/root422$ sudo apt-get remove fcitx-frontend-gtk2 [sudo] password for dingq: Reading package lists... Done Building dependency tree Reading state information...

实验一下：
dingq@u1110-120628:/nfsroot/root422$ gvim etc/inittab dingq@u1110-120628:/nfsroot/root422$先用gvim打开文件，再关闭，可以看到terminal中很干净，没有出现以前的错误提示。
问题解决。
