开机时提示
[ 6.787399] [drm:intel_dsm_platform_mux_info] *ERROR* MUX INFO call
failed
后来在nVidia的驱动说明文当里发现了这么一段：
The driver may be installed normally on Optimus systems, but the NVIDIA X
driver and the NVIDIA OpenGL driver may not be able to display to the
laptop's
internal display panel unless a means to connect the panel to the NVIDIA GPU
(for example, a hardware multiplexer, or "mux", often controllable by a BIOS
setting) is available. On systems without a mux, the NVIDIA GPU can still be
useful for offscreen rendering, running CUDA applications, and other
uses that
don't require driving a display.
现在我的显卡没法用OpenGL的程序（提示说Invalide OpenGL context），怀疑和
*ERROR* MUX INFO call failed有关，谁能帮忙解决以下？？
