Ubuntu 10.04 安装Nvidia显卡后开机花屏完美解决

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。



(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1280x800的所以我需要的是:1280x800-24

(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=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
