这个问题以前已经被回答过, 但是接受的答案中的方法在11.10上对我都无效。
首先，我尝试编辑/etc/default/grub，然后运行sudo update-grub。但是之后，当内核加载时，我仍然得到一个空白、纯粹的紫色屏幕。屏幕上没有引导选项，并且遮挡了我想要在终端中看到的那些dmesg信息。
接下来，我尝试移除plymouth-theme-*，但是那只是破坏了我的gnome-shell主题外观，而紫色屏幕仍然存在。
我还尝试使用startupmanager软件包进行配置，但似乎没有任何方法可以摆脱那个讨厌的紫色启动画面。
这里是我的/etc/default/grub文件的内容：

# /boot/grub/grub.cfg.
