在14.04上搭配optimus的Lenovo W530上无法配置双屏幕
我已经设法在我的Lenovo W530上安装了nvidia-331-updates驱动程序，如果我启动nvidia-settings，它会说：
** Message: PRIME: Requires offloading ** Message: PRIME: is it supported? yes 哪个好。 此外，我的xrandr设置似乎很好：

xorg.conf的内容应该是：
# cat /etc/X11/xorg.conf Section "ServerLayout" Identifier "layout" Screen 0 "nvidia" Inactive "intel" EndSection Section "Device" Identifier "intel" Driver "modesetting" BusID "PCI:0@0:2:0" EndSection Section "Screen" Identifier "intel" Device "intel" EndSection Section "Device" Identifier "nvidia" Driver "nvidia" BusID "PCI:1@0:0:0" Option "ConstrainCursor" "off" EndSection Section "Screen" Identifier "nvidia" Device "nvidia" Option "AllowEmptyInitialConfiguration" "on" EndSection
但是当我运行nvidia-settings时，它只是克隆屏幕，并且不会让我修改设置。 我想在插入显示端口时扩展到辅助屏幕。
编辑 ：
当我运行以下命令时：
# xrandr --output LVDS-1-0 --auto --output DP-0 --mode 1680x1050 --right-of LVDS-1-0 --verbose
它说 ：
crtc 0: 1680x1050 60.0 +1920+0 "DP-0" crtc 4: 1920x1080 60.0 +0+0 "LVDS-1-0"
以下内容附加到Xorg.0.log：

它看起来像是将DP-0（外部）屏幕设置为一个非常大的显示器，具有相同的原点（如此克隆）
您应该可以通过nvidia-settings执行此操作，但如果没有，请尝试此xorg.conf ：
Section "ServerLayout" Identifier "layout" Screen 0 "nvidia" 0 0 Inactive "intel" Option "Xinerama" "0" EndSection Section "Device" Identifier "intel" Driver "modesetting" BusID "PCI:0@0:2:0" EndSection Section "Device" Identifier "nvidia" Driver "nvidia" BusID "PCI:1@0:0:0" Option "ConstrainCursor" "off" Option "metamodes" "DP-0: 1680x1050, LVDS-1-0: 1920x1080" Option "TwinViewOrientation" "RightOf" EndSection Section "Screen" Identifier "nvidia" Device "nvidia" Option "AllowEmptyInitialConfiguration" "on" EndSection
或者，尝试以下命令：
xrandr --output DP-0 --mode 1680x1050 --output LVDS-1-0 --mode 1920x1080 --right-of DP-0
