ubuntu 18.04 on HP Pavilion 15 cx0140tx

## Major Specs
- Intel® Core™ i5-8300H CPU
- Intel® UHD Graphics 630 (Coffeelake 3x8 GT2)
- Nvidia GTX 1050M

### Install
- Add `nomodeset` to kernel boot line, else the install will freeze randomly.

### First boot
1. Add kernel argument : `nomodeset`

2. GDM edit
------------
- Force usage of X11 instead of Wayland by changing the line in `/etc/gdm3/custom.conf` that has:
```
#WaylandEnable=false
```
to
```
WaylandEnable=false
```

3. No audio fix
----------------
- reference link : https://www.linuxuprising.com/2018/06/fix-no-sound-dummy-output-issue-in.html
- Only fix needed is Fix#2:
```
echo "options snd-hda-intel dmic_detect=0" | sudo tee -a /etc/modprobe.d/alsa-base.conf
```

4. Blacklist nouveau driver
---------------------------
```
$ sudo bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
$ sudo bash -c "echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
$ sudo update-initramfs -u
```

5. Update Grub
```
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash modprobe.blacklist=nouveau"
```

6. Install nvidia headless
--------------------------
- Refer Xorg settings : https://gist.github.com/wangruohui/bc7b9f424e3d5deb0c0b8bba990b1bc5#2-configure-xorg
- Install MLRepo and CUDA repo hosted by Nvidia (refer steps 1-7 : https://gist.github.com/christianramsey/52b74ecc4048f8e3e9ae84afc3ee810b)
- Then:
$ sudo apt install nvidia-headless-440 nvidia-compute-utils-440

7. Install CUDA headless (no dependency on nvidia-driver-440 (with opengl)
--------------------------------------------------------------------------
$ sudo apt install cuda-minimal-build-10-1 cuda-libraries-10-1 cuda-nvcc-10-1 cuda-gdb-10-1 cuda-memcheck-10-1
