How to switch nvidia driver from "nouveau" to nvidia proprietary

i'm using Linux Mint. I recently updated my workstation, and from this moment, my drivers went nuts. I was working fine before, with the nvidia-361 drivers, and, when i finished my updates, and after rebooting the PC, il was running in "software rendering mode". I finally get to have a correct desktop, but now, i'm quite sure the card isn't fonctionning properly, because i can't launch any simple game with 3D (like blazeRush for example, wich was running fine before). This is the result of a lspci -vnnn 01:00.0 VGA compatible controller : NVIDIA Corporation GF104 [GeForce GTX 460] [10de:0e22] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Gigabyte Technology Co., Ltd GF104 [GeForce GTX 460] [1458:34fc] Flags: bus master, fast devsel, latency 0, IRQ 124 Memory at dc000000 (32-bit, non-prefetchable) [size=32M] Memory at d0000000 (64-bit, prefetchable) [size=128M] Memory at d8000000 (64-bit, prefetchable) [size=64M] I/O ports at e000 [size=128] Expansion ROM at de000000 [disabled] [size=512K] Capabilities: Power Management version 3 Capabilities: MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: Express Endpoint, MSI 00 Capabilities: [b4] Vendor Specific Information: Len=14 Capabilities: Virtual Channel Capabilities: Power Budgeting Capabilities: Vendor Specific Information: ID=0001 Rev=1 Len=024 Kernel driver in use: nouveau Kernel modules: nvidiafb, nouveau, nvidia_375_drm, nvidia_375 As you can see, the kernel driver in use is "nouveau", but i would like to use nvidia_375 instead. I already tried to purge with apt like this sudo apt purge *nvidia* xserver-xorg*nouveau* bbswitch* but when i do that, after a reboot, "nouveau" is still here ... i can try to install again the proprietary drivers, but i will be back in the same situation as before the purge. I'm running out of options.
