That means you must have been /using/ the modesetting DIX driver.

You likely created a new problem. modesetting_drv.so is the default DIX for AMD,
Intel and NVidia GPUs. fbdev is unaccelerated, and won't support most common
widescreen display modes. Some apps won't run on it. I don't think Gnome will even
start using it. Using fbdev you can expect your PC to feel like it's running a
single core at 233MHz instead of 2000MHz or more on multiple cores.
I don't know that I've ever migrated an installation using SDDM to another PC
using a majorly different GPU. I use TDM or KDM3 on most installations, with a
rare few on LightDM or SDDM, whose themes I always have extreme negative
appreciation for.
