Comment 241 for bug 1268257

@dino99

This is not fixed with nvidia-340. I have Xubuntu 14.04 with nvidia-340 and nvidia-304-uvm installed from the xorg-edgers PPA. It seems nvidia-libopencl1-340 depends on nvidia-340-uvm. I just installed the 3.19.3 vivid kernel from here:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19.3-vivid/

And got the usual error:

Consult /var/lib/dkms/nvidia-340/340.76/build/make.log for more information.

I tried examining /var/lib/dkms/nvidia-340/340.76/build/make.log, but the file does not exist.

The usual:

$ sudo dpkg-reconfigure nvidia-340

and:

$ sudo dpkg-reconfigure nvidia-340-uvm

seem to have worked:

$ sudo dpkg-reconfigure nvidia-340
