Profile-sync-daemon

I haven't had much luck with this so far.

I've tried it twice, and Firefox became very unstable.

rEFInd

  • Install rEFInd
refind-install
  • Create the themes directory for refind
cd /efi/EFI/refind
  • On refind installation path, clone the catppuccin repo inside a themes directory
mkdir themes && cd themes

git clone https://github.com/catppuccin/refind.git catppuccin
  • Edit the mocha.conf file, commenting the last line
nano catppuccin/mocha.conf

#showtools hidden_tags

For some reason the rEFInd showtools variable is not working properly for me anymore, this is why I have to comment this line on catppucin's mocha file

  • Edit the refind.conf, making sure to add a new menuentry for the systemd-boot and also including the mocha.conf file
nano ../refind.conf

timeout 5

[...]

menuentry "Arch Linux" {
    icon /EFI/refind/themes/catppuccin/assets/mocha/icons/os_arch.png
    volume "ARCHIE_ESP"
    loader /EFI/systemd/systemd-bootx64.efi
}

include themes/catppuccin/mocha.conf

Virtual Machine

Check the hardware virtualization support

# the output should be > 0
grep -Ec '(vmx|svm)' /proc/cpuinfo
Make sure the virtualization is enabled in the BIOS

For AMD, look for the SVM option. For Intel, look for the VMX option

Install the necessary packages

sudo pacman -Syu virt-manager qemu-desktop dnsmasq iptables-nft

Enable the libvirtd service

sudo systemctl enable --now libvirtd.service

Add the user to the libvirt group

sudo usermod -aG libvirt $env.USER

Restart the service

systemctl restart libvirtd.service
