I reboot after installation, my computer shows the manjaro boot options interface. I choose manjaro, but it shows me my computer logo instead of the manjaro loading animation and the login interface. please help me figure out it, appreciate…
two pieces of NVMe (nvme0 loaded Windows10, I installed manjaro in nvme0n1p3)
display card: hd630 + gtx1060m
I install succeed before, I re-install recently.
typo, actually win10 installed in nvme0(one partition), manjaro installed in nvme1n1p3
Welcome to the forum! 
Please post your system info as outlined here:
If you’re not able to get to a terminal, the info can be obtained while booted from the live USB.
Thanks for the tips!
I’ve installed manjaro gnome minimal 21.0.7 and had no problem. Then, after a pacman -Syu I’ve had the same problem. For me, a (kinda) solution was to switch to tty2 when this happens (ctrl+alt+f2), then back (ctrl+alt+f1). After this, the login screen loads, but gnome does not load the themes. Currently don’t know the problematic package, because as I simply reverted to my timeshift snapshot before the update.
My GPU specs: Intel UHD 620 + Nvidia mx150
EDIT
So, after some restarts the problem appeared in 21.0.7 as well, and after updating (again) it seems the not loading theme was a different problem. So after all, I can not add anything to the problem. Sorry
BUT the (kinda) solution still applies, using that seems to result in an otherwise problem-free system
