Hi guys! So...yeah. I have a Chuwi Minibook X N150 laptop that I'm testing around. Seems so far, so good regarding hardware support, with even the camera working on apps like the zoom flatpak. There's one thing that keeps irking me though, and that's the GRUB boot menu. It's all rotated to the left (90º counter-clockwise). This is probably because they're using some sort of tablet 1080p LCD screen. Once logged in, the acceleration sensors (took a couple of boots to get them working) take over, and determine what is up and down. At the SDDM login screen, I can handle it with a quick xrandr --output mydisplay --rotate right. But...GRUB? Seems grub ignores me.

I have tried by now things such as: GRUB_CMDLINE_LINUX="video=efifb fbcon=rotate:3", or GRUB_CMDLINE_LINUX="i915.fastboot=1 fbcon=rotate:3" or even: GRUB_FB_ROTATION=270

But so far, nothing sticks, and the screen remains locked at a 90 degree angle. Any ideas of what could I do to sort it out?

I have KDE Neon installed, which is an Ubuntu 24.04 so far.

Thanks!
