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。
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。
(2)安装所需包：
sudo apt-get install v86d hwinfo
(3)查看framebuffer
sudo hwinfo --framebuffer
我的显示器分辨率是1680x1050的所以我需要的是：1680x1050-24
(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=1680x1050-24,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=1680x1050
# 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=1680x1050-24 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
