I can't draw a triangle when I use TRIANGLE_LIST, but LINE_LIST is right

I’ve struggle with this question for several days, I cant’t find the reason.

The question is when I set assemble toplogy with VK_PRIMITIVE_TOPLOGY_LINE_LIST/STRIP, it run mormally,
but when I changed the assemble toplogy to VK_PRIMITIVE_TOPLOGY_TRIANGLE_LIST/FAN/STRIP, it display nothing.

I use GTX1070, the PC system is Ubuntu 18.04

I’ve find the point. the point was in the VkPipeline create.

void TKPipeline::initRasterStateCreateInfo(){
m_rasterState.sType = VK_STRUCTURE_TYPE_PIPELINE_RASTERIZATION_STATE_CREATE_INFO;
m_rasterState.pNext = nullptr;
m_rasterState.flags = 0;
//m_rasterState.depthClampEnable = VK_FALSE;
//m_rasterState.rasterizerDiscardEnable = VK_FALSE;
m_rasterState.polygonMode = VK_POLYGON_MODE_FILL;
m_rasterState.cullMode = VK_CULL_MODE_NONE;
m_rasterState.frontFace = VK_FRONT_FACE_COUNTER_CLOCKWISE;
//m_rasterState.depthBiasEnable = VK_FALSE;
//m_rasterState.depthBiasConstantFactor = 0.0f;
//m_rasterState.depthBiasClamp = 0.0f;
//m_rasterState.depthBiasSlopeFactor = 0.0f;
m_rasterState.lineWidth = 1.0f;
}
when I set the CULL_MODE to VK_CULL_MODE_FRONT_BIT or others which are not VK_CULL_MODE_NONE, I can’t draw a solid triangle.
May be ther are some special properties I don’t konw about Nvidia GPU .
