我正在尝试在 ubuntu 16.04 系统中添加一些缺失的显示,我按照以下站点进行配置:
http://ubuntuhandbook.org/index.php/2017/04/custom-screen-resolution-ubuntu-desktop/
dev@mysite-dev:~$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192

dev@mysite-dev:~$ cvt 1920 1080

[sudo] password for dev:
dev@mysite-dev:~$ sudo xrandr --addmode eDP-1 "1920x1080_60.00"
xrandr: cannot find output "eDP-1"
dev@mysite-dev:~$
正如您所看到的,我收到以下错误:
xrandr: cannot find output "eDP-1"
答案1
失败是因为您的输出显示未被调用eDP-1
,您需要将其替换为您正在使用的输出显示。
sudo xrandr --addmode `xrandr | grep -e " connected [^(]" | sed -e "s/\([A-Z0-9]\+\) connected.*/\1/"` "1920x1080_60.00"
该命令将输出您当前连接的显示,在我的情况下是LVDS-1
:~$ xrandr | grep -e " connected [^(]" | sed -e "s/\([A-Z0-9]\+\) connected.*/\1/"
LVDS-1
