okay my friend seeing you are new you best redo your installation, that sure be easiest. That is if you have a nvidia graphic card. Then install Garuda choosing the nvidia option. After installation run the update, however watch the process and see if the nvidia dkms modules throw up an error. If so after the update open a terminal ( Press Ctrl-t) and enter the code below, this will install the open source dkms driver and modules and could well fix your issues. (When you run the code below it may tell you there are dependency issues. simply uninstall the conflicting files and re run the code.
sudo pacman -Sy nvidia-open-dkms egl-wayland lib32-nvidia-utils lib32-opencl-nvidia nvidia-settings opencl-nvidia nvidia-utils
Hope this helps.
to uninstall a file
sudo pacman -R ‘conflicting file name’
after the code has successfully finished reinstall the conflicting files if possible, otherwise simply leave them, for then you have the latest driver already.
to reinstall
sudo pacman -Sy ‘packet name you unistalled before’
if the above does not work try this instead
