The os is Federa 15. gnome3. I install vim-X11 and input "gvim" in terminal. the gvim can be used. But the terminal also output some error:
(gvim:4431): 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
