I was trying to log into my main administrator account, and it seems to accept my username & password and begin to login normally, as the standard (for me) blank purple screen pops up, but then it goes to a black prompt screen, little white cursor blinking, then brings me straight back to the greeter.
I remember something similar happening before on my old Chromebook, though not exactly the same, because...
I made a root user account (I know, I know...) that I swear I haven't touched, but when I tried to login with THAT account, from the greeter, Gallium booted up just fine. So maybe I can fix the problem from that side?
Oh, also, I've already tried to remove the USB flash drive I have for extra space, etc, before booting and updated the RW_LEGACY Firmware. Neither worked.
If I have to reinstall, I guess that's all there is to it. But hopefully not.
