如何使用C#获取Ubuntu上的图形处理器信息？

using System;
using System.Management;

class Program
{
    static void Main(string[] args)
    {
        try
        {
            ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_VideoController");
            foreach (ManagementObject queryObj in searcher.Get())
            {
                Console.WriteLine("设备名称: {0}", queryObj["Name"]);
                Console.WriteLine("制造商: {0}", queryObj["AdapterCompatibility"]);
                Console.WriteLine("驱动程序版本: {0}", queryObj["DriverVersion"]);
                Console.WriteLine("显存大小: {0} MB", queryObj["AdapterRAM"] != null ? Convert.ToInt32(queryObj["AdapterRAM"]) / 1024 / 1024 : 0);
                Console.WriteLine("-----------------------------------");
            }
        }
        catch (ManagementException e)
        {
            Console.WriteLine("发生错误: " + e.Message);
        }
    }
}
