我正在尝试让我的旧 1280x1024 显示器（连接到 DVI-I-0）与 Ubuntu 配合使用。我尝试的显示器是旧的 AOC VGA 显示器，通过 DVI-I 到 VGA 适配器连接到 Nvidia GTX960。我尝试使用 添加模式xrandr，但没有成功。
我曾尝试运行：
sudo xrandr --newmode "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync
进而
sudo xrandr --addmode 1280x1024_60.00
但命令返回错误：
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: 47
Current serial number in output stream: 48
xrandr 的输出：
