I have just bought an Clevo w650sr, everything work except the nvidia graphic card.
It has nvidia 750m together with a haswell CPU, Core i7-4700MQ.
I have done some research and found out that I need the Nvidia 319 driver (or never). So I have tried installing that. I have tried installing it from both the Nvidia website, and from the xorg edgers ppa. But I can't get it to work. After I have installed the driver, Unity is gone, and the GUI around the programs. I have tried doing
sudo nvidia-xconfig
But after this, I just get a 600x480 resolution.
If I search in "additional drivers" I find nothing. There is noe option in BIOS to "hard set" the GPU to the Nvidia one. I have also tried installing Bumblebee without any luck.
I have also search around on askubuntu, but I can't find anyone that have gotten an 750m to work with haswell CPUs.
