Ubuntu18.04键盘、鼠标不能用
最近在搞jetson nano的远程桌面控制，Ubuntu18.04系统。安装向日葵后可以正常远程操作。
但是在启动时出问题了——不连接显示器的情况下启动nano，不会自动进入桌面图形界面，这时候再用向日葵发起远程控制会显示连接出错。

怎么引起的
在/etc/X11/xorg.conf配置文件中添加以下内容（GPT教的）：
Section "ServerFlags"
Option "AutoAddDevices" "False"
EndSection
重启后发现不连接显示器时依然不会自动启动桌面，而此时外接的鼠标、键盘都不能用了（2.4g指示灯都没亮）。
GPT说这行代码用来禁用自动添加设备。
删除这几行代码后重启系统，鼠标、键盘可以用了。
在网上又找了个大佬写的使用虚拟显示器的文章：文章链接
sudo apt-get installxserver-xorg-core-hwe-18.04
sudo apt-get installxserver-xorg-video-dummy-hwe-18.04--fix-missing
安装了使用虚拟显示器的相关文件库后，发现使用这种方法后，会出现即使外接了显示器，信号也不会输出到显示器上的情况（只能用虚拟显示器，不能用物理显示器了，我是这么理解的）。
所以到这步就停了，没有继续跟着走下去。
但是重新启动nano后，鼠标、键盘又不能用了，不知道是为什么？？？？
有没有大佬知道在哪个地方出了问题了，求助！！！
或者有什么方法让系统跳过屏幕检测程序，直接开机后就能远程控制。。
PS：也跟着上述文章链接创建了/usr/share/X11/xorg.conf.d/xorg.conf，并添加了相关内容，但是由于看见这个操作会使物理显示器不能用，所以就把xorg.conf文件移出了xorg.conf.d目录，放到了桌面自己创建的一个目录下，不知道和这个有没有关系。
有没有大佬知道怎么才能让鼠标键盘能用，现在想控制系统只能远程操作，太麻烦了，期待各位大佬的回答。
纯纯纯新手操作，确实不懂，希望能有大佬看见

[ 506.182] (--) NVIDIA(GPU-0): AOC 24B1W1 (DFP-0): External TMDS 根据您提供的信息，可能有几个原因导致键盘和鼠标无法使用：
1. 在xorg.conf配置文件中禁用了自动添加设备。这可能导致系统无法识别和使用键盘和鼠标。您可以尝试删除这些配置并重启系统，看看是否解决了问题。
2. 安装了虚拟显示器相关的文件库后，无法使用物理显示器。这可能导致系统无法检测到键盘和鼠标。您可以尝试卸载这些文件库并重启系统，看看是否解决了问题。
3. 在启动时不连接显示器，系统无法自动进入桌面图形界面。这可能导致键盘和鼠标无法使用。您可以尝试连接显示器并重新启动系统，看看是否解决了问题。
如果上述方法都无法解决问题，您可以尝试以下方法：
1. 在启动时按下Ctrl+Alt+F1，进入终端模式。然后尝试使用命令行控制系统。
2. 在终端模式下，检查系统的输入设备是否被正确识别。您可以使用以下命令查看输入设备列表：
ls /dev/input/
如果键盘和鼠标设备在列表中显示，请尝试重新配置它们。
3. 检查系统的日志文件，查看是否有与输入设备相关的错误或警告信息。您可以使用以下命令查看日志文件：
cat /var/log/Xorg.0.log
如果发现与输入设备相关的错误或警告信息，请尝试解决这些问题。
如果您仍然无法解决问题，建议向Jetson Nano的社区或论坛寻求帮助。他们可能会有更具体的解决方案或建议。 怀疑是没有指定输入驱动程序，但是不知道该怎么解决 isdkz 发表于 2023-9-25 16:00

感谢您的回答，但如果您借鉴了ChatGPT给出的答案，那么这些方法我已经尝试过了，包括删除配置文件中禁用自动添加设备的部分，卸载虚拟显示器相关文件库，连接显示器并重新启动等，均不能使我的键盘鼠标恢复使用。另外在启动时进入终端模式，由于我的键盘输入被禁用了，无法通过同时按下Alt、Ctrl、F1方法进入。但是因为我在连接显示器后，可以远程控制桌面，所以可以实现使用终端命令和查看相关文件。系统日志文件关于鼠标输入的报错我已经粘在了本帖原文内，根据日志文件内容，可能是驱动程序没有被指定，但是我不知道该怎么解决这个问题，或者请问您有这方面的解决经验吗 不懂诶，虽说我也用Ubuntu，但了解有限{:10_262:} 或许你可以去更大的平台比如知乎之类的去问问 yinda_peng 发表于 2023-9-26 18:29
