Ubuntu 15.04 桌面缺少启动屏幕

Ubuntu 15.04 桌面缺少启动屏幕

我使用 Unetbootin 安装了 Ubuntu 15.04。(与 Windows 7 双启动)。
但在启动 Ubuntu 时,我得到一个粉红色的屏幕(与 grub 默认背景颜色相同),几秒钟后变为黑色(不是逐渐过渡),然后大约 10 秒后(平均启动时间)Ubuntu 登录屏幕出现,然后一切正常。没有显示 Ubuntu 启动动画。其他一切正常。我该如何解决这个问题?

笔记:

I was having this problem since the first boot.
I am using default graphic driver

我认为你无法修复它,这取决于你的显卡驱动程序,默认情况下有正常的 ubuntu 动画,如果你更改驱动程序,启动可能会看起来不同(我已更改,并且只显示 Ubuntu 14.04 文本和闪烁的点)。如果你有默认的,也许某个地方有问题,尝试安装 Super Boot Manager 并更改 Plymouth。

  1. 按住Shift
  2. 在 GRUB 中按C打开命令行
  3. 启动命令vbeinfo查看所有分辨率,例如。1920x1200x32
  4. 重新启动系统
  5. 打开文件/etc/default/grub

    sudo nano /etc/default/grub
    

    并添加或更改行

    GRUB_GFXMODE=<your_resolution>
    

    例如:

    GRUB_GFXMODE=1920x1200x32
    

    现在添加或更改行

    GRUB_GFXPAYLOAD_LINUX=keep
    
  6. 保存配置并启动命令

    sudo update-grub
