再次,Ubuntu 在 Dell XPS 13(9350,2016 型号)上出现了一些奇怪的问题。我拿到了 Dell DA200 适配器(USB-C 转 HDMI/VGA/以太网/USB3.0)来连接外接显示器。我测试了两台显示器:一台有 VGA 端口,另一台有 VGA 和 DVI 端口。以下是我的测试结果:
Ubuntu, DVI-connection with screen: no display (though linux recognizes it)
Ubuntu, VGA-connection both screens: working display
Windows, DVI-connection with screen: working display
- 内核:4.6.0-040600rc7-generic
- Linux:Ubuntu 16.04
- 显示管理器:Gnome
编辑:问题不在于系统完全无法工作。它显然只适用于某些分辨率。我目前的屏幕分辨率为 1680x1050。此显示器的标准分辨率为 1920x1080。但是,我在工作时有一台 Dell U2515H (2560x1440),该分辨率也不起作用。我还没有尝试过 1920x1080 和 2560x1440 之间的任何分辨率,但我希望任何分辨率都能正常工作。

编辑 2:屏幕设置为工作分辨率时的输出与设置为非工作分辨率时的输出相同。以下是非工作分辨率的输出:

答案1
看来这是与 i915 相关的内核错误。错误报告已在此处提交https://bugs.freedesktop.org/show_bug.cgi?id=93578。我们需要等待修复。
