In the past I've successfully installed Garuda. Recently though I'm interested in trying it more extensively. I've run into a bit of an issue. I can't log in. Like the password is correct and it tries to show me the startup screen and then it just immediately goes right back to the login screen.
I can verify the password is correct because when I enter the wrong password it tells me the password is wrong.
I was experiencing a similar or the same issue with my fresh install on a nvidia optimus laptop with graphic switching enabled, and with an external display connected to my computer. Running sddm through the ctrl+alt+f3 terminal I was able to see error messages about the displays, so I tried disconnecting my external display. This allowed me to login normally, and after a round of post-install updates I'm able to login with that display connected. I can't remember the exact error message, so apologies for that.
This is a known issue with SDDM/KDE. First time is safer to start with only one monitor. After setup, it's OK to add external monitors.
Plasma has a big issue with multihead, so they created a specific bug tracker tag for that, to focus on fixing all issues.
