我以前运行 17.10,一切运行正常。升级后,第二台显示器停止工作。它在 Windows 中运行良好,但我不想使用 Windows。我的显卡是 AMD RX 480。
我将内核升级到最新的稳定内核 (4.17.9-041709-generic),并将 mesa 升级到最新版本。不幸的是,这些都无济于事。我还进入并将/etc/gdm3/custom.conf
设置 wayland 更改为 false,但这也不起作用。当我进入此内核版本的恢复模式时,它可以工作,但无法加载到 gnome 中。它卡住了。
这是我的 xrandr:

我也遇到了同样的问题。将显示管理器从 gdm3 更改为 lightdm 解决了我的问题。
安装 LightDM
sudo apt install lightdm
运行并在对话框中dpkg-reconfigure
选择lightdm
sudo dpkg-reconfigure lightdm
值得注意的是,我安装了最新的可用 Nvidia 驱动程序:
