Automatic mount disc

To make the partition auto-mount, first find out the UUID of /dev/sda3 by doing:

sudo blkid

I'll assume you're using ext4 on /dev/sda3. Open up gedit like so:

sudo -H vim /etc/fstab

Now you want to add a line to the bottom of that file. It should look something like this (UUID will be different):

UUID=03ec5dd3-45c0-4f95-a363-61ff321a09ff /works ext4 defaults  0      2

For more info on fstab, this is a good resource - https://wiki.archlinux.org/index.php/Fstab.

Deleting Windows hibernate metadata As an alternative to above clean shutdown method, there is a way to completely destroy NTFS metadata that was saved after hibernating. This method is only feasible if you are not able or unwilling to boot into Windows and shut it down completely. This is by placing remove_hiberfile option when you are mounting your NTFS file system using ntfs-3g.

mount -t ntfs-3g -o remove_hiberfile /dev/your_NTFS_partition /mount/point

Proton - Sound

I tried the WINEPREFIX solution mentioned above to no avail, ended up finding protontricks that stratus mentioned on github soon after.

Here is what worked for me:

Fetch protontricks from github and mark executable wget https://raw.githubusercontent.com/Sirmentio/protontricks/master/protontricks && chmod +x protontricks

move protontricks to /usr/bin so it can be ran from terminal sudo mv protontricks /usr/bin/protontricks

setup xact for banished on steam protontricks 242920 xact

run winecfg for banished prefix using protontricks protontricks 242920 winecfg

click on libraries and add xact and xaudio2_7, leave them with native, builtin https://i.imgur.com/lvguBoG.png

this is with Ubuntu 18.04, WINEPREFIX solutions did not work for me in this case, but this did.

Game performance

CpuFreqUtils

Install cpufrequtils:

sudo apt-get install cpufrequtils

Then edit the following file (if it doesn't exist, create it):

sudo vim /etc/default/cpufrequtils

And add the following line to it:

GOVERNOR="performance"

Save and exit.

Now you need to disable ondemand daemon, otherwise after you reboot the settings will be overwritten.

sudo update-rc.d ondemand disable

And you are done!

You can check your settings with:

Boot failing

ALERT! /dev/mapper/ubuntu-vg-root does not exist. Dropping to shell!

Gave up waiting for root device. Common problems:
  — Boot args (cat /proc/cmdline)
    — Check rootdelay= (did the system wait long enough?)
    — Check root= (did the system wait for the right device?)
  — Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/mapper/ubuntu--vg-root does not exist. Dropping to a shell! 

BusyBox v.1.21.1 (Ubuntu 1:1.21.1-1ubuntu1) built-in shell (ash)   
Enter 'help' for list of built-in commands.  

(initramfs)

In certain Ubuntu versions (e.g. Xubuntu 18.10) this issue might be caused by an apt autoremove. Due to this bug apt will suggest to remove

cryptsetup cryptsetup-bin cryptsetup-initramfs cryptsetup-run dmeventd libdevmapper-event1.02.1 liblvm2app2.2 liblvm2cmd2.02 libreadline5 lvm2

Fix (in liveCD/liveUSB):

# find root partition
sudo fdisk -l

# unencrypt partition
#   Note: replace /dev/nvme0n1p3 with your disk
#         replace "nvme0n1p3_crypt" with the correct name 
#         check by running this in chroot:
#         $ cat /etc/crypttab | cut -f1 -d " "
#         nvme0n1p3_crypt
sudo cryptsetup luksOpen /dev/nvme0n1p3 nvme0n1p3_crypt

# mount root partition
sudo vgscan 
sudo vgchange -ay
sudo mount /dev/mapper/ubuntu--vg-root /mnt

# prepare chroot environment
sudo mount /dev/nvme0n1p2 /mnt/boot/   # replace nvme0n1p2 with your boot partition!
sudo mount -o rbind /dev/ /mnt/dev/
sudo mount -t proc proc /mnt/proc/
sudo mount -t sysfs sys /mnt/sys/

# make dns available in chroot
sudo cp /etc/resolv.conf  /mnt/etc/resolv.conf 

# enter chroot
sudo chroot /mnt /bin/bash

# re-install missing packages
apt install cryptsetup lvm2

# re-generate  (this might be done also by apt in the step before, I'm not sure)
update-initramfs -u -k all

# Leave chroot environment - not sure if the following is really necessary...
exit
# Write buffers to disk
sudo sync
# Unmount file systems
sudo umount /mnt/sys
sudo umount /mnt/proc
sudo umount /mnt/boot

Upgrading

if we get something like this:

The following packages have unmet dependencies:
 winehq-stable : Depends: wine-stable (= 5.0.0~bionic)

We do this:

# Add i386 architecture
sudo dpkg --add-architecture i386
sudo apt update

# remove old repository
sudo apt-add-repository -r 'deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main' 

# Download key for new repository
wget -nv https://download.opensuse.org/repositories/Emulators:/Wine:/Debian/xUbuntu_18.04/Release.key -O Release.key

# Add key
sudo apt-key add - < Release.key

# Add repository (opensuse)
sudo apt-add-repository 'deb https://download.opensuse.org/repositories/Emulators:/Wine:/Debian/xUbuntu_18.04/ ./'

sudo apt-get update

# Stable branch     
sudo apt install --install-recommends winehq-stable

#Development branch     
#sudo apt install --install-recommends winehq-devel

#Staging branch     
#sudo apt install --install-recommends winehq-staging
