Hello I’ve just tried adding this grub params to disable Plymouth but still not The weird thing is that after a system update I tried, It got stuck so I shutted down the machine through power button. Then I have this error which couldn’t find vmlinuz, which I solved it using manjaro-chroot and updating the system again as suggested in this post so after that I could open up again the computer as usual. Then I had to shutdown through power button, as something weird happened since last summer where the shutdown command was not properly shutting down the machine…
And at that point is where I am, that I cannot access the OS withouth adding nomodeset param
