我有一台笔记本电脑，正在尝试插入两个显示器，其中一个应该运行在2560x1440
我已经安装了专有nvidia-331-updates驱动程序，并且（我认为）将其配置为默认使用这些驱动程序（prime-select nvidia）
我有一个Intel(R) Core(TM) i7-3537U CPU @ 2.00GHz和一个Nvidia 710m正在运行的 Ubuntu 14.10
当我尝试通过以下方式设置分辨率时：
~$ cvt 2560 1440
~$ xrandr --newmode "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync
~$ xrandr --addmode HDMI1 "2560x1440_60.00"
~$ xrandr --output HDMI1 --mode 2560x1440_60.00
我收到错误：xrandr: Configure crtc 2 failed
输出xrandr --verbose

更新：
按照此处的说明进行操作： https://plus.google.com/+LinusTorvalds/posts/HQsCY7ErAL4 我能够让它输出而没有错误，但现在我的显示器出现“超出范围”错误
答案1
尝试使用 nvidia-settings -> X Server Display Configuration -> Detect Displays。我已成功使用它在两个显示器上显示桌面（一个@2550x1440，另一个@1920x1080）。
答案2
很抱歉，但你运气不好。显示2560x1440像素需要使用更高的图形芯片频率，即使这在芯片的规格范围内，笔记本电脑制造商也会禁用高于该频率的任何功能1920x1080以防止过热。
我还没有看到笔记本电脑的规格说明Support of external monitor @2560x1440 pixels。
您可以将闪亮的显示器与具有带 HDMI 输出的独立卡的台式工作站一起使用 - 前提是该分辨率在卡的规格范围内。
