The following are what I did:
- sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libqt5gui5 libgles1-mesa-lts-utopic libgles2-mesa-lts-utopic libgl1-mesa-glx-lts-utopic libgl1-mesa-glx-lts-utopic:i386 libglapi-mesa-lts-utopic:i386 libegl1-mesa-drivers-lts-utopic
Except it reported that it cannot locate dkms.conf, everything goes well.
- sudo add-apt-repository ppa:xorg-edgers/ppa
- sudo apt-get update
- sudo apt-get install nvidia-346
After that, I can find an application called "NVIDIA X Server Settings" in my application list, and everything looks normal in it. It can even show the tempature of my GPU.
But sudo lshw -C display still cannot show my nvidia GTX 850M (I have already enabled NVIDIA):
*-display description: 3D controller product: GM107M [GeForce GTX 850M] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a2 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:55 memory:f6000000-f6ffffff memory:e0000000-efffffff memory:f0000000-f1ffffff ioport:e000(size=128) memory:f7000000-f707ffff *-display description: VGA compatible controller product: 4th Gen Core Processor Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 06 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:52 memory:f7400000-f77fffff memory:d0000000-dfffffff ioport:f000(size=64)
I am not sure is there any problem in my question, I think maybe I need describe what I expect in more details. I think if the driver is installed successfully, after I sudo lshw -C display, the "VGA compatible controller" should also be nvidia one, but now it still is Intel Integrated one.
If I am correct, does anyone can tell me what should I do to make the VGA compatible controller to nvidia one. If I am wrong, how could I know whether my naughty GPU is running or not. Thanks a lot!!!
