我最近在 Windows 双启动中安装了 Ubuntu，我正在努力让 Ubuntu 正确检测我的分辨率。
我有一个 1920x1080 的屏幕，但当我运行时xrandr，我得到了这个
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 32767 x 32767
LVDS1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 345mm x 194mm
1366x768 60.0*+
1360x768 59.8 60.0
1024x768 60.0
800x600 60.3 56.2
640x480 59.9
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
我在网上搜索了一段时间，当我运行时gtf 1920 1080 60，我得到了
# 1920x1080 @ 60.00 Hz (GTF) hsync: 67.08 kHz; pclk: 172.80 MHz
Modeline "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsyn
我尝试添加这样的新模式
xrandr --newmode "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync
当我尝试时xrandr --addmode LVDS1 1920x1080_60.00，我得到了这个
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: 37
Current serial number in output stream: 38
之后newmode，xrandr给了我
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 32767 x 32767

v: height 1080 start 1081 end 1084 total 1118 clock 60.0Hz
你知道我该怎么做才能让它发挥作用吗？
先感谢您。
