OK, after compiling 5.0.7 mainline + Ubuntu Patches + this patch from here (https://patchwork.freedesktop.org/patch/296411/) to fix the link training issue for my laptop panel, I am able to boot with modesetting.
Now I *am* noticing the problem. As others have suggested, bending back the laptop panel on it's hinge "resets" the keyboard and trackpad, then I can bend it back to a normal position and everything starts working.
One other thing worth mentioning is that the problem also exhibits itself in lightdm, not just gdm3.
