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附件:

(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"
-------------------------------------------------------------------------------------------------------------------
第二步:
代码:
sudo gedit /etc/grub.d/00_header
找到代码:
set gfxmode=${GRUB_GFXMODE}
在其下一行添加
代码:
set gfxpayload=keep
第三步:
代码:
sudo update-grub
(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_moduvesafb 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
