我的电脑上有以下设置：
- OpenSuse Leap 42.1
- Geforce GT 430（带两个显示器：DVI-I-1-1 和 VGA-1-2）
- 第三个显示器连接到板载显卡（Radeon 3000）。
在 BIOS 中，我设置了启动至 VGA-Onboard 的选项，目前我正在正确地同时运行三台显示器。实际上，操作并不是最佳的，因为当我移动窗口时图像被剪切，我认为这一定是因为 GPU 没有使用 NVIDIA 驱动程序。
这是我的 xrandr 输出、lspci 和 lshw（我的 xorg.conf 为空）。

为了尝试解决这个问题，我从 YAST (computeG04) 安装了 NVIDIA 驱动程序，并且仅支持连接到 Radeon 的显示器，并且 xrandr 不检测 GPU 接口。
目前我卸载了 NVIDIA 驱动程序并使用 nouveau 驱动程序。
我可以做什么来解决这个问题？
