過了4個月，才有耐心解決這個問題。
A. 安裝官方的驅動程式，以下參考手把手網站的內容
- 請先去Nvidia官網下載你的驅動程式
名字太長了我改成 nvidia.run並放到~/ (家目錄)下面 - 要賦予nvidia.run執行權限才能安裝哦
- chmod +x nvidia.run
- 移除nvidia舊版並移除舊的設定檔
- sudo apt-get --purge remove nvidia-*
- 安裝編譯所需套件與核心 (這一個步驟我有點問題…說linux-restricted-modules...找不到)
- sudo apt-get install build-essential libc6-dev pkg-config xserver-xorg-dev linux-headers-$(uname -r) linux-restricted-modules-$(uname -r) nvidia-settings gcc gcc-3.4
- 請按Ctrl+Alt+F1進入文字終端機
- 中斷X windows才能正確安裝顯示卡驅動程式
- sudo /etc/init.d/gdm stop
- 開始安裝nvidia官方版驅動程式
- sudo sh ~/nvidia.run
- 接著就進入了Nvidia的授權頁，第一個選accept同意他的授權聲明 按tab鍵可移動
- There appears to already be a driver installed on your system (version: 173.14.12). As part of installing this driver (version: 173.14.12), the existing driver will be uninstalled. Are you sure you want to continue? ('no' will abort installation) (Answer: Yes)
- No precompiled kernel interface was found to match your kernel; would you like the installer to attempt to download a kernel interface for your kernel from the NVIDIA ftp site (ftp://download.nvidia.com)? (Answer: No)
- Install NVIDIA's 32-bit compatibility OpenGL libraries? (Answer: No)此項只有amd64版本才會出現
- Would you like to run the nvidia-xconfig utility to automatically update your X configuration file so that the NVIDIA X driver will be used when you restart X? Any pre-existing X configuration file will be backed up(Answer: Yes)
- sudo sh ~/nvidia.run
- 最後回到x windows會看到一個Nvida的畫面，這樣就代表安裝好了
- sudo /etc/init.d/gdm start
- 咱們來看看有沒有安裝成功
- glxinfo | grep "OpenGL version string:"
OpenGL version string: .....
- lspci | grep VGA
01:00.0 VGA ......
- glxinfo | grep "OpenGL version string:"
我試了n偏，仍然無效，最後在外國的討論區才發現重要的步驟
these options were critical
Option "ExactModeTimingsDVI" "TRUE"
Option "ModeValidation" "NoEdidModes"
貼上我的 xorg.conf
Section "Monitor"
Identifier "Monitor0"
Vendorname "Generic LCD Display"
Modelname "LCD Panel 1920x1080"
Horizsync 31.0-83.0
Vertrefresh 56.0 - 76.0
Option "DPMS"
Option "ExactModeTimingsDVI" "TRUE"
Modeline "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync
EndSection
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
EndSection
經過我的試驗，如果少了藍字，解析度依然無效。多了橘字…畫面字會糊掉
我不知道為什麼…這次的經驗，讓我對ubuntu的喜愛程度大打折扣
