我有一台华硕 Q536fd，已经与 Ubuntu 一起使用了一段时间。我使用过多个版本，都存在以下问题。我目前使用的是 Ubuntu 20.04，但曾使用过 18.10、19.04、19.10。因此，问题如下：
使用 Nouveau 驱动程序：
- 输入密码后，操作系统需要一两分钟的时间才能离开紫屏并实际启动 GUI。
- 此外，从挂起状态唤醒后，触摸板大约 30 秒内无法工作，但触摸屏仍然可以工作，外接鼠标也可以工作。
使用 NVIDIA 440 驱动程序（或任何其他驱动程序）：
- 上述问题消失了，但我的 Wi-Fi 连接似乎不起作用。我在 Chrome 中加载一个页面，它只是不停地旋转。连接在那里，但它从未加载过任何页面。Firefox 中也发生了同样的事情。
- 此外，软件和更新程序也不再起作用（可能是因为 Wi-Fi 无法正常工作）。
如能得到任何帮助/指导，我将不胜感激。谢谢！

答案1
所以最后我继续安装卸载 nvidia 驱动程序。最终我的设备不再“看到”nvidia gpu，这实际上是一个福音。我认为我的设备在集成显卡芯片和 nvidia gpu 之间发生争斗，并导致了所有这些问题（即使是 nouveau）。现在没有 nvidia 芯片被识别，我不再有登录问题。我的触摸板没有问题，我的 wifi 工作得很好！
所以答案是：如果您不需要 nvidia gpu，那么请将其从驱动程序中完全卸载。
