在 ubuntu 20.04 上,它不允许我设置原始分辨率,我尝试将屏幕分辨率设置为,1920x1080 (16:9)
但选项没有显示,唯一的选项是1024x768 (4:3)
这就是我从xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected primary 1024x768+0+0 0mm x 0mm
1024x768 76.00*
这就是我从sudo lshw -C video
