Everything was working a couple of days ago. Apparently the installation of virtualbox using zypper somehow (??) resulted in the un-installation of my Nvidia drivers, because now when I run any Cuda code, including the samples, it just fails. So I tried to re-install the Nvidia drivers using the exact same method that was working last Friday.
It asks all the same question it was asking last Friday, but now it says
Installing the NVIDIA display driver…
The driver installation is unable to locate the kernel source. Please make sure that the kernel source packages are installed and set up correctly.
If you know that the kernel source packages are installed and set up correctly, you may pass the location of the kernel source with the ‘–kernel-source-path’ flag.
Of course, the kernel-source is installed on this system, and I’d be pretty surprised if its location had changed, due to the use of zypper to install VirtualBox??:
fourier:~ # zypper se kernel

So the kernel-source module is isntalled, but I do not know how to query its location. Maybe VirtualBox modved it?
So I uninstalled virtualbox the same way it had been installed, using zypper. This succeeded, but the same error still persists.
I am trying a reboot next. I’ll post back here to let you know if that fixes the problem, but I doubt it. Have already rebooted once after virtualbox install and once more during the foregoing problems. No help from that so far.
