我有一台 3840x2160 的笔记本电脑,我想将其连接到 3440x1440 的显示器,但是使用 Ubuntu(Ubuntu 18.04 LTS)屏幕显示设置,其中一个显示器的缩放比例要么太小要么太大。
我按照这里的说明进行操作:https://wiki.archlinux.org/index.php/HiDPI#Multiple_displays
并运行以下命令:
xrandr --output eDP-1 --auto --output DP-2 --auto --panning 3840x2160+3840+0 --scale 2x2 --right-of eDP-1
但输出是这样的:
xrandr: screen cannot be larger than 8192x8192 (desired size 10720x2880)
运行xrandr -q
结果如下:
Screen 0: minimum 320 x 200, current 3840 x 2160, maximum 8192 x 8192
