Hi @Fabby, I have same laptop (Asus fx505dt) with same configuration.
I also got the same issue. After trying bunch of different methods. I just removed non-free drivers video-hybrid-amd-nvidia-450xx-prime and started using free drivers video-linux .
Everything works fine now.
Also, method mentioned by @visone did not work for me, It gives error ‘cannot start SDDM’ at start.
@Fabby that’s alright. I just wanted to confirm if solution works with everyone.
Also, The solution I gave above does not work in all conditions. I apologize for that.
I just found the solution here on forums that works and I have thoroughly tested it.
Please check point 4.0 Suspend Issues.
If someone is having same problem, please let me know.
also for an update : the issue gets resolved if I switch to nvidia 440.x.x.x. but the system automatically upgrades itself to 450+.x.x. and that causes the issue again and again

Warning: No installed USB configs!
I install those from harware configuration settings
also I am on manjaro gnome .
I think it upgrades whenever I upgrade my machine via pamac manager or install a new package …
in that case what can I do ?
Hey , sad to say but After trying the method u suggested , broke the screen and starten flickering again… I then deleted uninstalled the driver then again installed … now its working
I first went to TTY2 then removed the drivers and then installed em again . came back to home … got blamed with the flickering issue again … I then removed the driver via gui and then installed it again . It worked .
That’s totally and utterly weird, because it should do the same thing, but on TTY2 you can remove all drivers and still be able to reboot (back into the TTY only though) and then fix any issues that cannot be fixed thorugh a GUI…
