在配备 GeForce GTX 1050 Ti/PCIe/SSE2 的 Dell G3 15 上，我通过 HDMI 连接到外部 (acer) 显示器。我没有任何图像 (屏幕是黑色的)，有时会被蓝点或蓝线覆盖。
我保证：
- HDMI 线没有损坏
- 监视器正在工作
- 我试过几台新显示器
- 我尝试了不同的刷新率
- 我尝试了 xorg 驱动程序和几个 NVIDIA 驱动程序
- 切换到 Wayland；Ubuntu 16.04 和 19.04
sudo ubuntu-drivers autoinstall

答案1
问题似乎出在 nvidia persistence 守护进程中。这是我上次启动时的工作系统的样子（我每天多次暂停和恢复，而不是重新启动）：

我第一次设置笔记本电脑时也遇到了问题nvidia-persistenced，需要用谷歌搜索才能解决。
