我已经在 ubuntu 服务器上安装了vulkan 。但是，当我跑步时，vulkaninfo我得到

WARNING: [Loader Message] Code 0 : loader_icd_scan: Can not find 'ICD' object in ICD JSON file /usr/share/vulkan/icd.d/nvidia_layers.json.  Skipping ICD JSON
ERROR: [Loader Message] Code 0 : loader_scanned_icd_add: Could not get 'vkCreateInstance' via 'vk_icdGetInstanceProcAddr' for ICD libGLX_nvidia.so.0
ERROR: [Loader Message] Code 0 : vkCreateInstance: Found no drivers!
Cannot create Vulkan instance.
This problem is often caused by a faulty installation of the Vulkan driver or attempting to use a GPU that does not support Vulkan.
ERROR at /build/vulkan-tools-1.3.224.0~rc2-1lunarg18.04/vulkaninfo/vulkaninfo.h:672:vkCreateInstance failed with ERROR_INCOMPATIBLE_DRIVER

的输出nvidia-smi

我最近购买了 Lenovo Ideapad 720s (4K) 和 Dual Booted Ubuntu 18.04。但是屏幕闪烁。即使在安装时我也遇到了这个问题，但认为一旦设置了 Ubuntu 就不会发生这种情况。我已经尝试过华硕 Zenbook UX391UA 中提到的方法 - 屏幕闪烁但仍然没有成功。我附上了相同的视频：
https ://youtu.be/Fz7JkVIMPlk

规格：
8GB RAM
Core i7-8550U
Intel UHD Graphics 620 (Kabylake GT2)
GNOME 3.28.2

我发现的唯一解决方法是拔下电源，然后重新插入。（有效率为 98%）。这个问题让我的生活变得悲惨，因为一旦我锁定屏幕（并且屏幕关闭），它就会重新出现。

请帮忙！
