Dell Precision M4700上的Nvidia Quadro K2000M – 驱动程序无法正常工作
我刚刚安装了新的Ubuntu 12.04 LTS，并从他们的网站（304.60最新的Long Lived分支机构）安装了nvidia驱动程序。
他们只是不工作。 分辨率低至640×540或其他。 我运行sudo nvidia-xconfig得到结果：
Using X configuration file: "/etc/X11/xorg.conf". Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup' New X configuration file written to '/etc/X11/xorg.conf' 但是当我尝试用nvdia-settings打开设置时，我得到：
You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server.
因此我重新启动X服务器（sudo restart lightdm），但我再次得到相同的结果。
这是我的xorg.conf文件：
memecs@memecs-drz:~$ cat /etc/X11/xorg.conf # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 304.60 (buildmeister@swio-display-x86-rhel47-04.nvidia.com) Sun Oct 14 21:34:47 PDT 2012 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Unknown" HorizSync 28.0 - 33.0 VertRefresh 43.0 - 72.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Depth 24 EndSubSection EndSection
任何帮助都非常感谢。 谢谢！
问题解决了。 需要从BIOS禁用optimus。 一切正常。
