我正在尝试扩展我的外接显示器,以允许我的 4k/1080p 设置运行并且实际可见的东西,但却xrandr
拒绝让我做任何事情:
我的命令xrandr --output HDMI-1-1 --auto --scale 2x2
输出以下内容:
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 26 (RRSetCrtcTransform)
Value in failed request: 0x40
Serial number of failed request: 38
Current serial number in output stream: 39
执行后,我的屏幕闪黑片刻,但又恢复原样,这表明设置根本没有被应用。
我的系统配备了 NVIDIA Optimus,目前正在使用 Prime 运行所有内容,如prime-select query
返回所示nvidia
。
如果我在笔记本电脑的内置显示器上运行此命令,缩放功能可以正常工作,但仍会抛出错误。出于某种原因,它只会在我的外接显示器上完全被忽略。
至于为什么我不只是缩放我的另一台显示器,它造成烦恼我目前还没有可行的解决方案。
发生了什么事?更重要的是,我该如何解决这个问题?
