联想Y450花屏闪屏_土豆_高清视频在线观看Ubuntu 10.04 ***Nvidia显卡后开机花屏完美解决
笔记本联想Y450，Ubuntu 10.04.3 LTS
1.可以解决的问题：
（1）***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）
（1）***驱动：
方法一，Nvidia官网下载最新驱动，但是得先屏蔽掉nouveau，而且***后会出现Nvidia巨大的Logo,我没有用 这种方法。
方法二，System--&Administration--&Hardware Drivers。
我使用的是第一种，不过有点问题，需要先禁用自带的nouveau
步骤如下：
用官方驱动***，将驱动拷到主文件夹，然后按Ctrl+Alt+F1退到终端并登录，sudo /etc/init.d/gdm stop，然后运行sudo sh ./Nv.......（驱动软件名），它会提示nouveau在使用，然后会问你是否建立一个文件来禁止nnouveau，选择Yes，一直点下去，会退出到终端界面，sudo reboot重新启动到GDM桌面，然后按Ctrl+Alt+F1退到终端，并登录，sudo /etc/init.d/gdm stop，退掉X桌面，再次运行sudo sh ./Nv.......（驱动软件名），就会正常***驱动了，***完sudo reboot，完成。
如果照着上面的做了，还会提示nouveau在使用，那就是没有完全屏蔽掉，因为内核还是在加载nouveau。10.04.3LTS和10.10以后版本好像都不行。解决方法：
生成&/etc/modprobe.d/nvidia-installer-disable-nouveau.conf&文件后，要执行：
update-initramfs -u
update-grub2
再重启系统，就可以***NVIDIA官方驱动了。
（2）***所需包：
sudo apt-get install v86d hwinfo
（3）查看framebuffer
sudo hwinfo --framebuffer
结果如下：
tsl0922@ubuntu:~$ sudo hwinfo --framebuffer

我的笔记本分辨率是的所以我需要的是：
（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=,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=
# Uncomment if you don't want GRUB to pass &root=UUID=xxx& parameter to
#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:
uvesafb mode_option= 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
