1.可以解决的问题：
（1）安装驱动后开机和关机画面花屏，分辨率低；
（2）开机画面直接出现，一闪而过，错过点点进度过程。（这个我原来幼稚地认为是10.04的开机速度太快，进度条来不及显示呢。呵呵）
2.解决方案：uvesafb 替代 vesafb（具体什么意思我也不知道）
3.所需包：
（1）v86d（uvesafb需要）
（2）hwinfo（查看framebuffer）
4.步骤
（1）安装驱动：
方法一，Nvidia官网下载最新驱动，但是得先屏蔽掉nouveau，而且安装后会出现Nvidia巨大的Logo,我没有用 这种方法。
方法二，System-->Administration-->Hardware Drivers，我选的是那个Recommended。
sudo apt-get install v86d hwinfo
（3）查看framebuffer
sudo hwinfo --framebuffer
（4）修改grub文件
sudo gedit /etc/default/grub
-------------------------------------------------------------------------------------------------------------------
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1280x800-24,mtrr=3,scroll=ywrap"
GRUB_CMDLINE_LINUX=""
# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=1280x800
# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true
# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_LINUX_RECOVERY="true"
# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"
-------------------------------------------------------------------------------------------------------------------
（5）修改initramfs:
sudo gedit /etc/initramfs-tools/modules
-------------------------------------------------------------------------------------------------------------------
# List of modules that you want to include in your initramfs.
#
# Syntax: module_name [args ...]
#
# You must run update-initramfs(8) to effect this change.
#
# Examples:
#
# raid1
# sd_mod
uvesafb mode_option=1280x800-24 mtrr=3 scroll=ywrap
-------------------------------------------------------------------------------------------------------------------
（6）强制使用Framebuffer:
echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splash
（7）更新grub和initramfs:
sudo update-grub2
sudo update-initramfs -u
（8）重启
