我的显卡是 GT 710。从物理上讲，我已经正确安装了它。但是lspci -v没有在任何地方显示 Nvidia 显卡。以下是输出（由于篇幅过长，省略了详细信息，因此仅显示条目）：
00:00.0 Host bridge: Intel Corporation 4 Series Chipset DRAM Controller (rev 03)
00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) (prog-if 00 [VGA controller])
00:02.1 Display controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)
00:1c.0 PCI bridge: Intel Corporation 82801JD/DO (ICH10 Family) PCI Express Port 1 (rev 02) (prog-if 00 [Normal decode])
00:1c.4 PCI bridge: Intel Corporation 82801JD/DO (ICH10 Family) PCI Express Port 5 (rev 02) (prog-if 00 [Normal decode])
00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev a2) (prog-if 01 [Subtractive decode])
我也尝试过lspci | grep 3D并且没有返回任何内容。
lspci | grep VGA仅显示Intel Corporation 4 Series ...，这是默认的板载显卡：
00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)
不过，我还是继续尝试安装驱动程序。我按照如何安装 Nvidia 驱动程序？，安装 nvidia-381，这是最新的驱动程序。安装后我打开了，Nvidia X Server Settings但没有PRIME profiles，尽管nvidia-prime旁边自动安装了nvidia-381并bumblebee删除了。
sudo nvidia-xconfig返回了：
WARNING: Unable to locate/open X configuration file.
Package xorg-server was not found in the pkg-config search path.
Perhaps you should add the directory containing `xorg-server.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xorg-server' found
New X configuration file written to '/etc/X11/xorg.conf'
我尝试重新安装xorg，openbox但没有任何改变。
我搜索了已安装驱动程序的问题，并尝试了这个已安装 Nvidia 驱动程序，但未使用.我执行了sudo update-alternatives --config x86_64-linux-gnu_gl_conf：
There are 3 choices for the alternative x86_64-linux-gnu_gl_conf (providing /etc/ld.so.conf.d/x86_64-linux-gnu_GL.conf).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/nvidia-381/ld.so.conf 8604 auto mode
1 /usr/lib/nvidia-381-prime/ld.so.conf 8603 manual mode
2 /usr/lib/nvidia-381/ld.so.conf 8604 manual mode
* 3 /usr/lib/x86_64-linux-gnu/mesa/ld.so.conf 500 manual mode
Press <enter> to keep the current choice[*], or type selection number:
将选项改为0，即/usr/lib/nvidia-381/ld.so.conf。但是重启后选项又变回了/usr/lib/x86_64-linux-gnu/mesa/ld.so.conf。我认为有很多问题，但这些问题可以归因于 Ubuntu 无法检测到显卡。
如果您有任何想法我将不胜感激。
编辑：这是lspci -v
