完美解决Ubuntu 10.04开机和关机分辨率过低

Ubuntu 10.04开机和关机分辨率过低

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framebuffersudo hwinfo –framebuffer

我的显示器分辨率是1280×800的所以我需要的是:1280×800-24(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=0GRUB_HIDDEN_TIMEOUT=0GRUB_HIDDEN_TIMEOUT_QUIET=trueGRUB_TIMEOUT=10GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash nomodeset video=uvesafb:mode_option=1280×800-24,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=1280×800

# 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_moduvesafb mode_option=1280×800-24 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-grub2sudo update-initramfs -u(8)重启。

怀着淡定从容的心态去面对,也就没有了真正意义上的寂寞了。
