Routers
#!/usr/bin/env bash
# Alright so, this hotel decided to put up separate SSIDs for each room. This
# is kind of annoying since we've been moved 3 times and since it's a large
# property. T-Mobile also doesn't have coverage here so the moment we step out
# of our rooms we can't make or receive calls even though we're still in range
# of the hotel's wifi networks.
#
# Also interesting is that the hotel decided to use a few models of router (as
# far as I can tell they're all cable + wifi router devices) *and* decided to

nvidia-390 w/5.3.0-28 on hera on an xps 9560

since i don't have a blog, i'm going to dump here:

  • /lib/modules/<kernel version>/updates/dkms isn't what dkms uses anymore for, at least for ubuntu provided HWE and other patched kernels; instead it's /lib/modules/<kernel version>/extras so make your symlinks so that X and bumblebee and friends don't flip out
  • you can use the graphics ppa (ppa:graphics-drivers/ppa or just the stock ubuntu contrib/non-free bionic ppas)
  • install: bbswitch-dkms prime-select acpi-call-dkms nvidia-390 bumblebee bumblebee-nvidia (if you don't install this one you'll suffer like me) and (crucially!) your linux kernel's headers! (i.e.: linux-headers-generic-hwe-18.04-edge or linux-headers-5.3.0-26-generic) (note: install your headers before you install the other things or if you don't go run dkms manually)
  • nvidia drivers are no longer symlinked to /usr/lib/nvidia-current so change /etc/bumblebee/xorg.conf.nvidia and /etc/bumbleebee/bumblee.conf's contents to match ([this](https://github.com/Bumb
#!/usr/bin/env bash
# Go to the directory where you want to install all these things:
# - i.e.: `mkdir -p /dev/shm/__ && cd !$`
#
# Copy this script into that dir:
# - i.e.: `cp <path/to/script> !$`
#
# And then source this script:
# - i.e.: `source sourceme`
