我有一台 Acer ET322QK 显示器。它适用于 Windows 10、Ubuntu 18.04 和 Linux4Tegra。但是,当我将计算机与新安装的 Ubuntu 20.04 连接时,它似乎无法正确使用显示器。在“连接”模式下,它是黑色的。如果我镜像它,它将在显示器的四分之一上显示桌面,但我无法用鼠标控制任何东西。当我尝试将其用作唯一显示器时,它让我处于某种状态,我必须通过按下电源按钮重新启动计算机才能再次获得控制权。
值得注意的是,设置可以很好地识别显示器。它将其列为“Acer Technology 32 英寸”,我可以从中选择的分辨率列表看起来是正确的。
我看到很多关于显示器不工作的帖子,通常可以通过更新驱动程序或其他东西来解决。但是,我不擅长这些事情。有人能建议我在这种情况下应该怎么做吗?如果我需要驱动程序,我怎么知道哪一个?
至于设置中的附加驱动程序:
默认设置是“使用 X.Org X 服务器”,这似乎是效果最好的。图片中选定的那个似乎无法识别显示器,因为它不会显示显示菜单。
dpkg -l *nvidia*
在终端运行结果如下:
