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，它会显示：
** Message: PRIME: Requires offloading
** Message: PRIME: is it supported? yes
这很棒。此外，我的 xrandr 设置似乎很好：

xorg.conf 的内容如下：
# cat /etc/X11/xorg.conf

但是当我运行 nvidia-settings 时，它只是克隆屏幕，不允许我修改设置。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"

它看起来像是将 DP-0（外部）屏幕设置为非常大的显示屏，具有相同的原点（因此克隆）

您应该可以做到这一点nvidia-settings，如果不行，请尝试以下操作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，尝试这个命令：
xrandr --output DP-0 --mode 1680x1050 --output LVDS-1-0 --mode 1920x1080 --right-of DP-0
