Hmm, it looks like the installer has set “in” as the keymap according to your language/keyboard layout selection, but it is not actually an available keymap in localectl list-keymaps. Honestly I’m not sure which of your available keymaps will be closest for you; maybe you can look through the list yourself and see if you recognize any of those options.
Once you decide on a keymap that will work for your keyboard, edit /etc/vconsole.conf and change the KEYMAP= line to use that keymap. For example, to switch to the us keymap:
sudo micro /etc/vconsole.conf
KEYMAP=us
Then rebuild the initramfs.
sudo dracut-rebuild
Reboot, and test again if you can start a Hyprland session normally.
Describe what you have done leading up to “nothing working” with as much detail as possible. You are the only one who can see your computer at the moment; “nothing working” is not enough information to determine what the issue is.
us-en is not an available keymap in the output from localectl list-keymaps. Please, review the output if you are not sure. It is this link you posted: https://termbin.com/n3ih
Did you regenerate the initramfs afterward? What was the output from that?
Please post again, after a reboot:
garuda-inxi | nc termbin.com 9999
cat /etc/vconsole.conf | nc termbin.com 9999
Then try running again:
hyprstart
If it fails, post the new log the same way as the last time.
No, this is not appropriate. If you can’t get this working on your own you should choose another spin; it is specifically mentioned on the download page that the Hyprland spin is intended for advanced users only.
