升级到 17.10 后 Unity 上的屏幕大小和快捷方式问题

  • 772

升级后的两个问题：

  1. 在 Unity 会话中登录后，出现一个对话框错误，说

所需的虚拟大小不适合可用大小：请求=（1,1），最小=（320,200），最大=（8192,8192）

我想知道要求的尺寸（1,1）是什么，但不知道在哪里搜索......无论如何，我可以正常工作，但是（不知道它是否相关）：

  1. 没有全局键盘快捷键起作用（例如volumeUp/Down、Super-L 来阻止屏幕等）。本地快捷方式（例如 Ctrl-Space 打开我最喜欢的启动器）有效。

在升级之前没有出现任何问题。

    简短的回答

    尝试将屏幕分辨率更改为较低的分辨率，然后从系统控制 - 显示更改回原始分辨率，然后重新启动以检查。

    长答案

    所需的虚拟大小不适合可用大小：请求=（1,1），最小=（320,200），最大=（8192,8192）

    此错误消息看起来像xrandr一个。因此，我要求将更多图形信息添加到问题中。

    dmidecode -s system-product-name; echo ==; lshw -c display; echo ==; xrandr --verbose

    来源：为什么会发生 xrandr 错误“BadMatch”、“BadName”、“Gamma Failed”？

    可能的问题：

    1. 错误或缺少驱动程序，但我们从输出中发现没问题：

      configuration: driver=i915 latency=0

    2. 配置中存储的虚拟屏幕大小错误，可以通过更改分辨率来重置。这解决了它。
