【问题描述】：
我使用的是 ubuntu 18.04（我有 ubuntu 18.04 的双启动窗口）。
nvidia-smi
这是我在 ubuntu(18.04) 终端上运行上述命令时得到的输出：
Fri Oct 9 09:33:56 2020

在此之前，我按照以下步骤在我的系统上安装所需的驱动程序：
sudo add-apt-repository --remove ppa:graphics-drivers/ppa
sudo apt-get purge nvidia*
sudo apt autoremove
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo ubuntu-drivers devices
sudo ubuntu-drivers autoinstall
sudo shutdown -r now
当我尝试运行Geekbench5 计算基准测试时，输出在运行直方图均衡时停止。这是我在提取 geekbench5 的文件夹中运行 ./geekbench5 --compute OpenCL 时的输出：
[1009/092949:FATAL:src/halogen/cuda/cuda_library.cpp(1481)] Failed to load
cuDevicePrimaryCtxRetain: /usr/lib/x86_64-linux-gnu/libcuda.so.1: undefined symbol: cuDevicePrimaryCtxRetain

Geekbench 5.2.4 Tryout : https://www.geekbench.com/
Geekbench 5 is in tryout mode.
Geekbench 5 requires an active Internet connection when in tryout mode, and
automatically uploads test results to the Geekbench Browser. Other features
are unavailable in tryout mode.
Buy a Geekbench 5 license to enable offline use and remove the limitations of
tryout mode.
If you would like to purchase Geekbench you can do so online:

If you have already purchased Geekbench, enter your email address and license
key from your email receipt with the following command line:
./geekbench5 -r <email address> <license key>

此外，当我尝试在 Windows 10（同一台机器，在 GUI 上）上运行 geekbench5 计算基准测试时，它在直方图均衡时暂停运行。
不知道为什么会这样.有人可以帮忙吗？
