Hi. I installed Manjaro for the first time today, and used 19.12.
On initial boot my monitor didn't get a chance to display any text at all (i.e. there's no sign of a boot loader). Instead, my monitor switches to a message saying it can't display the video mode.
It's a Dell monitor whose native resolution is 1600x1200 at 60Hz.
I'd seen a video online of somebody installing 19.08 on the same hardware, so I tried installing that instead. It booted fine, installed smoothly, and I created a user account.
Then I ran
pacman -Syu (which went smoothly) and rebooted. Again, my monitor says it can't display the video mode.
Has anything changed in the pre-login graphics mode between 19.08 and 19.12?
And how I could edit the startup files to get it running a basic text mode during bootup? I can ssh in to fiddle with the settings fairly easily.
One last thing — this is Manjaro ARM on a Raspberry Pi 4. I didn't post this in the ARM forum as I suspect that the problem is caused by a change to the features between Manjaro 19.08 and 19.12. If I'm wrong about that, feel free to move it...
