nvidia-settings复杂问题

我全新安装了 Ubuntu 16.04，并且仅在 ssh 中使用它。我有几个nvidia gpu。

这就是我安装驱动程序的方式（在谷歌中找到信息）：

--------------------------驱动程序安装---------- ----

准备：

sudo dpkg --add-architecture i386
sudo apt update
sudo apt install build-essential libc6:i386

禁用默认的 Nouveau NVIDIA 驱动程序

sudo bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
sudo bash -c "echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf"

 更新内核 initramfs

sudo update-initramfs -u
sudo reboot

下载最新驱动https://www.geforce.com/drivers

sudo sh NVIDIA-Linux-x86_64-440.83.run
sudo reboot

之后检查

sudo lspci -vnn | grep -i VGA -A 18

--------------------------结束驱动程序安装---------- -----

之后 gpus 与驱动程序正常工作。但

 nvidia-settings
** (nvidia-settings:2285): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-G3kXDTdi54: Connection refused
ERROR: Unable to load info from any available system

在export NO_AT_BRIDGE=1的帮助下解决了第一个警告

关于错误：无法从任何可用系统加载信息，我发现我需要

sudo prime-select nvidia

Info: the current GL alternatives in use are: ['mesa', None]
Info: the current EGL alternatives in use are: ['mesa-egl', None]
Error: the installed packages do not support PRIME
Error: nvidia mode can't be enabled

现在我不知道如何解决这一切......
