Switch from Manjaro to Arch without fresh install
WARNING!!! After the switch neither Manjaro nor Arch community will be supporting you. No guarantee. What are you doing is your own risk! Make a backup first!
First of all you will need to download a new mirrorlist
sudo wget -O /etc/pacman.d/mirrorlist https://www.archlinux.org/mirrorlist/all/
then edit your new mirrorlist and remove any mentions of manjaro* from /etc/pacman.conf
sudo rm /etc/lsb-release
sudo pacman -Syyu pacman-mirrorlist
If you are faced with errors due to broken dependencies- remove the issue package before. (in my case it was
linux41-nvidia* to be removed).
sudo pacman -R manjaro-system sudo pacman -Syyu pacman
Note that if you start getting "warning ... SyncFirst in section 'options' not recognised" you will need to comment that line out.
sudo sed -i 's/^SyncFirst/#&/' /etc/pacman.conf
Removing and reinstalling packages
sudo pacman -Rsn $(pacman -Qsq manjaro-) sudo pacman -Syu alsa-utils alsa-firmware lib32-alsa-plugins sudo pacman -Rsn pulseaudio pulseaudio-alsa sudo pacman -Sy pulseaudio pulseaudio-alsa sudo pacman -Rsn lib32-mesa lib32-nvidia-utils libgl lib32-libgl
If you don't have libgl* packages installed go ahead to the next step
sudo pacman -Sy libgl lib32-libgl --force
You will want to choose an appropriate packages to be installed (in my case it was nvidia-related ones). You will want to agree to remove mhwd. If during removing there is an error regarding mhwd-tui remove it first.
sudo pacman -Rsn $(pacman -Qsq mhwd)
Setting up Arch installation
sudo pacman -S grub
You will want to merge /etc/default/grub.pacnew with the existing one (especially replacing GRUB_DISTRIBUTOR and commenting out color options).
sudo sed -i 's/^Manjaro/^Arch/' /etc/issue
Edit /etc/release to have it look like this:
NAME="Arch Linux" ID=arch PRETTY_NAME="Arch Linux" ANSI_COLOR="0;36" HOME_URL="https://www.archlinux.org/"; SUPPORT_URL="https://bbs.archlinux.org/"; BUG_REPORT_URL="https://bugs.archlinux.org/";
Copy the file to /etc/os-release and remove /etc/manjaro-release.
Installing kernel and graphics
sudo pacman -Sy nvidia-340xx
Replace it with your driver.
sudo pacman -Sy linux linux-api-headers linux-headers linux-firmware
- Boot to grub and choose Arch Linux
- Remove remained Manjaro Linux kernels
- Reinstall packages that are marked as newer than available.
