旧 Nvidia GeForce GT 620M 卡安装 Bumblebee

今天在leap 15.0通过以前的添加bumblebee源安装N卡的方法操作，安装完成后，总不能用

[ERROR]Cannot access secondary GPU - error: Could not load GPU driver

弄了半天后，发现dmesg里

[   66.566920] nvidia-nvlink: Nvlink Core is being initialized, major device number 243
[   66.567211] NVRM: The NVIDIA GeForce GT 620M GPU installed in this system is

我可怜的旧卡NVIDIA GF108M [GeForce GT 620M]被抛弃了。
现在我正在想办法安装legacy驱动配合bumblebee

http://download.nvidia.com/opensuse/leap/15.0/x86_64/ 这里有390.XXX的nvidia驱动源

N卡驱动下载超级慢呀

我安装了这个源里的几个G04（390），好像缺少文件

$ optirun --status

$ optirun -v glxgears

并没有找到系统里有libGL.so.1

$ rpm -ql nvidia-computeG04 nvidia-gfxG04-kmp-default nvidia-glG04 x11-video-nvidiaG04|grep "\.so$"
/usr/lib/libOpenCL.so
/usr/lib/libcuda.so

/usr/lib64/libnvcuvid.so
/usr/lib64/libvdpau_nvidia.so
/usr/lib64/xorg/modules/drivers/nvidia_drv.so

也许可以试试将/usr/lib64/libGL.so.1软链接到/usr/lib64/nvidia下面

目前解决了，感谢！

原来libGL.so不是nvidia驱动里的文件

$ rpm -qf /usr/lib64/libGL.so
libglvnd-devel-1.0.0-lp150.1.1.x86_64

不过，只要

sudo ln -s /usr/lib64/xorg/modules/extensions/nvidia/nvidia-libglx.so /usr/lib64/nvidia/xorg/modules/extensions/libglx.so

optirun就能用了。（primusrun还不能，暂时不管它了）

与显卡驱动相关的好多名词，mesa,glx,gl,glvnd,gles,egl,gfx,xf86-video-intel,vdpau真是头晕
