Hey! I am using ubutnu 13.10 with kernel 3.12 installed from mainline repo. I also installed nvidia 319.60 drivers from run file with a patch for kernel 3.12. It seems that this kernel has capability to close and open nvidia GPU. Is it possible to follow which card is in use? I am not sure if it is working or not.
I fail in the kernel 3.12 with NVIDIA 325.15. Errors comparison.
You should patch with http://sourceforge.net/projects/openpctv/files/sources/nvidia-319.60_kernel-3.12.patch/download?use_mirror=garr&r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fopenpctv%2Ffiles%2Fsources%2F&use_mirror=garr
but there is no need for that now. Nvidia released 331.20 which have support for kernel 3.12 but I still could not figure out if the optimus is working or NVidia card is on all times.
For the patching process
./NVIDIA*.run --extract-only cd NVIDıa*
and in that folder copy the patch downloaded. Then
patch -p1 "nvidia patch name here" < nvidia-install
after that swtich to Ctrl+Alt+f1 and do the normal install.
Is anyone have an information about whetder the optimus is working or not in kernel 3.12??
Ooook. Probe… :)
IN my case not working in 325.15. Fail complete. Thanks.
