Post installation things

Once you've installed Linux and are on the desktop, before rushing to do things, you may want to do a couple of additional steps.

To change some config files (don't worry, it won't hurt), I'll recommend nano because it just works. To save a file, use CTRL+S and to exit CTRL+X.

Update your system caution

Updating your system can be a bit of a pain in the ass, as some of the packages can't be updated because they contain modifications to make them work on the PS4.

CAUTION

Arch-based distros have repositories for drivers, other distros might not.

Arch based distros (with driver updates)

• NOTE: CachyOS Lite already has this repo configured.

To update the drivers, you need to open the pacman config:

sudo nano /etc/pacman.conf

If you installed a distro from the forums, you may have go to the [Options] section and delete the lines IgnorePkg and IgnoreGroup.

Then, under the REPOSITORIES section, add this (GitHub):

[ps4-video]
SigLevel = Optional 
Server = https://dionkill.github.io/ps4-video-archlinux/repo/

NOTE

This repo will only work as long as the developer is updating it and keeping it online. It may be changed in the future.

Then, CTRL+S to save and CTRL+X to exit.

Finally, install the driver packages:

sudo pacman -Syu lib32-mesa-ps4 mesa-ps4 lib32-libdrm-ps4 libdrm-ps4 xf86-video-amdgpu-ps4

You should now have up-to-date drivers.

Debian/Ubuntu based distros (WITH Mesa updates, WIP)

Use triki1's updater (should be included in their distro releases now)

Use uar's script updater:

wget [https://uar.no/ps4/baikal/mesa-25.sh](https://uar.no/ps4/baikal/mesa-25.sh "https://uar.no/ps4/baikal/mesa-25.sh") && sudo sh mesa-25.sh

Debian/Ubuntu based distros (disabled Mesa updates)

To make sure that the PS4 packages don't get updated run the command below:

sudo apt-mark hold lib32-libdrm-git lib32-mesa-git libdrm-git mesa-git lib32-libdrm lib32-mesa libdrm mesa lib32-llvm-libs llvm-libs

Then, you should be free to update your system with:

sudo apt update
sudo apt upgrade

Otherwise, you can always update everything but not the driver packages.

Change username and password

Create a new user. Because changing current user is unsupported.

You can however change the password, by doing:

sudo passwd

And setting a new password.

Better ram management

To do that, we must use Swap.

Enabling Swap

CAUTION

It's ABSOLUTELY NOT recommended to use the internal HDD as swap, you'd just add fuel to the dumpsterfire of slowness that it already is. Disable it and move on.

Swap is storage that you are taking from your drive and allocating as "extra RAM": it works by moving unused software over there if extra main memory needs to be reserved for another program or game. This means we can improve the memory situation a little bit.

We will be using a swap file instead of a swap partition, as it's easier to change in size. First of all, we need to remove any existing swap:

sudo swapoff -v /swapfile  
sudo rm /swapfile

Then, we need to enable new swap (8GB for this tutorial, you may change it)

sudo dd if=/dev/zero of=/swapfile bs=1M count=2048 # Allocates 8GBs, to find
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

Finally, go to the fstab file, and check if the line /swapfile none swap sw 0 0 exists. If it doesn't, add it by going here and pasting it at the end of the file:

sudo nano /etc/fstab

Oh, and don't worry if you see that your installation is using a lot of memory. It's normal and is meant to happen in order to improve performance. Check this link to learn more.

Install more applications

To play games, these are the recommended softwares:

• Steam
• Heroic Games Launcher (for Epic, GOG and Amazon)
• Lutris (for other PC games not in those launchers)
• Fjord Launcher instead of those other shitty Minecraft launchers
  • Minecraft has graphical issues in versions newer than 1.21.5
• And a bunch of emulators!

TIP

In some distros you may need to uncomment DisableSandbox in /etc/pacman.conf.

To do that, if using anything other than Arch based distros, install from their repo or github.

If you chose an Arch based distro however, use pacman or yay to install your packages. All packages you can even think of and more are available.
