Linux下查看本机显示器分辨率：

我的显示器目前设定的分辨率为 1920×1080 (16:9) 。

我还试着按照教程来修改显示器分辨率，但是修改失败了。等后面再来尝试。

$ cvt 2560 1440# 2560x1440 59.96 Hz (CVT 3.69M9) hsync: 89.52 kHz; pclk: 312.25 MHzModeline "2560x1440_60.00"  312.25  2560 2752 3024 3488  1440 1443 1448 1493 -hsync +vsync$ xrandr --newmode "2560x1440_60.00"  312.25  2560 2752 3024 3488  1440 1443 1448 1493 -hsync +vsync$ xrandr --addmode DP-0 "2560x1440_60.00"X Error of failed request:  BadMatch (invalid parameter attributes)  Major opcode of failed request:  140 (RANDR)  Minor opcode of failed request:  18 (RRAddOutputMode)  Serial number of failed request:  43  Current serial number in output stream:  44$
