洒家闲来无事，想起原来曾经遇到过在笔记本上直接安装ubuntu出现过启动屏幕空白，无法继续安装的问题，因此这次打算来进行解决。

首先查了一下网上的资料，找到两帖。

一、显卡(NVIDIA GeForce 310M)启动时，在 grub 里加上 nomodeset 参数禁用 kms，不然会黑屏安装驱动 NVIDIA-Linux-x86-256.53.run修改 /etc/X11/xorg.confSection "Device"    Identifier    "Device0"    Driver        "nvidia"    VendorName    "NVIDIA Corporation"    Option        "ConnectedMonitor" "DFP-0"    Option        "CustomEDID" "DFP-0:/proc/acpi/video/IGPU/LCD0/EDID"EndSection加载 uvesafb 模块以修复启动 X 后切换控制台黑屏死机的问题 二、屏幕亮度安装 hal 即可调整屏幕亮度，直接在 gnome 的电源管理里调节sudo apt-get install hal 安装 acpid 和 acpi-support 可使调节屏幕亮度的快捷键工作，但是要自己写几个脚本。 三、声卡安装软件库的内核声音模块sudo apt-get install linux-backports-modules-alsa-lucid-generic-pae或者手动安装 alsa 最新版本 四、触摸板修改 /etc/default/grub，添加命令 i8042.nopnp，如下形式GRUB_CMDLINE_LINUX="i8042.nopnp"然后 sudo update-grub 更新安装 gpointing-device-settings 进行管理

This seems to be happening with nVidia graphic cards to fix this problem try to use the following solution i hope this would helpSolution1I have a HP Pavilion SLimline s7727cwith lspci giving meVGA compatible controller: nVidia Corporation C51 [GeForce 6150 LE] (rev a2)I was getting a blank screen (out of sync) on booting from the live cd.I worked around the problem as follows:* At install screen press F6 and select nomodeset and install Ubuntu as usual.* On first boot after install, press e on getting the GRUB bootloader.* Using arrow keys navigate to and delete quiet and splash and type the word nomodeset in their place* Press Ctrl and X to boot* You should now be able to login to your Ubuntu as usualFor those of you who do not know what to do next, in the taskbar click on System->Administration->Hardware drivers, and select and activate the nvidia current driver if you have an nvidia card like I do. The driver will be downloaded and activated automatically, and you will be prompted for a reboot.Solution 2Yes, I think you may be right about it being a graphics card problem. I think you may have the same problem that I did on my beat-up old Toshiba Satellite A10.So, here is what should work:At the very first screen, the one with just the rectangle (it’s meant to be a keyboard) and a human figure, press any key - spacebar will do.Then choose your language.Then make sure you have “Try Ubuntu without any changes” selected, and then press F6Add this to the end of the command line:    i915.modeset=0 xforcevesaThen press enter and it should boot successfully.Solution 31. Boot from the Ubuntu 9.10 CD2. Mount the internal HD and look for /etc/X11/xorg.conf - its missing!3. Copy a new “known good” xorg.conf file to the HD (I had to use sudo cp … otherwise I got permission problems)4. System boots fine.

我按照上面红色标注的内容进行操作，解决了这个问题。

但是发现每次重启都需要这样走一遍，因此需要将grub的配置文件修改掉：

sudo gedit /boot/grub/grub.cfg

在相应的quiet splash的地方改成nomodeset，保存退出即可！
