我有一台支持 2560x1440 分辨率的显示器，它通过 HDMI 连接到我的笔记本电脑。我使用相同的 HDMI 电缆和显示器连接运行 Windows 和 MacOS 的笔记本电脑，默认情况下支持 2560x1440。在 Ubuntu 上，我没有选择将分辨率设置为 2560x1440，默认为 1920x1080。
我尝试通过运行cvt --reduced 2560 1440 60来添加分辨率，并通过以下方式添加它
xrandr --newmode "2560x1440R" 241.50 2560 2608 2640 2720 1440 1443 1448 1481 +hsync -vsync
xrandr --addmode HDMI-1 2560x1440R
xrandr --output HDMI-1 --mode 2560x1440R
但是我得到xrandr：配置 crtc 0 失败。
这是我从xrandr --verbose获得的 HDMI-1 输出
