我在使用 Bumblebee 和 nVidia 驱动程序 331 时遇到问题。Bumblebee 配置正确吗?我在 Ubuntu Gnome 14.04 中使用它。以下是使用英特尔卡的结果:
mayor@K56CB:~$ glxgears
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
303 frames in 5.0 seconds = 60.559 FPS
300 frames in 5.0 seconds = 59.930 FPS
300 frames in 5.0 seconds = 59.928 FPS
300 frames in 5.0 seconds = 59.931 FPS
这里使用 optirun 或 primusrun,结果相同:
mayor@K56CB:~$ optirun glxgears
293 frames in 5.0 seconds = 58.461 FPS
300 frames in 5.0 seconds = 59.930 FPS
300 frames in 5.0 seconds = 59.929 FPS
300 frames in 5.0 seconds = 59.928 FPS
300 frames in 5.0 seconds = 59.930 FPS
使用 nVidia 时结果不应该有所不同吗?以上是 bumblebee.conf 中包含 nVidia 驱动程序的部分:
## Section with nvidia driver specific options, only parsed if Driver=nvidia
[driver-nvidia]
# Module name to load, defaults to Driver if empty or unset
KernelDriver=nvidia-331-updates
PMMethod=auto
# colon-separated path to the nvidia libraries
LibraryPath=/usr/lib/nvidia-331-updates:/usr/lib32/nvidia-331-updates
# comma-separated path of the directory containing nvidia_drv.so and the
# default Xorg modules path
XorgModulePath=/usr/lib/nvidia-331-updates/xorg,/usr/lib/xorg/modules
XorgConfFile=/etc/bumblebee/xorg.conf.nvidia
我是否应该删除/更改有关 nouveau 驱动程序的部分?
答案1
glxgears 不是基准测试工具,因此您只能看到显示器的刷新率(60Hz)。
如果两个命令都起作用并产生相同的输出,则表明 nvidia 卡可以正常工作。
