在 Ubuntu 19.04 中，2560x1600 59Hz 或 60Hz 没有 HDMI（在 xrandr 中为 DP-3）输出。
无论我尝试使用英特尔还是英伟达芯片，输出都限制为 30Hz。请注意，在 Windows 10 中使用相同的电缆和显示器，2560x1600 和 60Hz 可以正常工作。
在 60Hz 上使用 xrandr 添加自定义模式不起作用。更改配置不起作用。但是只要我保持 30Hz 设置和自定义 xrandr 设置，一切就会正常。

请帮助解决这个问题，或者帮我提交错误报告。这应该是开箱即用的。
答案1
我的额定频率为 60 Hz 的 4K 显示器和适配器在 60 Hz 下也无法工作。就像您一样，它在 30 Hz 下工作。然后我尝试了 45 Hz，它也工作了。我不断将其增加到 54 Hz，这也工作了。所以我创建了一个 54 Hz 的配置并将其放入xorg配置中。对我来说，从 30 Hz 跳到 54 Hz 可以减轻眼睛的很大压力。我认为从 60 Hz 降到 54 Hz 不会损失那么多。
这是我的xorg配置片段：
