Personally, I would not expect this to be related to mainboard firmware/bios issues as I have not had any issues with efifb and nvidia-drivers on several systems. What is your kernel-commandline? Mine is really simple: $ cat /proc/cmdline root=/dev/nvme0n1p3 I get the following in my dmesg for "efifb": ==== [ 8.717047] efifb: probing for efifb [ 8.717061] efifb: framebuffer at 0xd1000000, using 3072k, total 3072k [ 8.717062] efifb: mode is 1024x768x32, linelength=4096, pages=1 [ 8.717064] efifb: scrolling: redraw [ 8.717065] efifb: Truecolor: size=8:8:8:8, shift=24:16:8:0 [ 8.719748] fb0: EFI VGA frame buffer device ==== Which is nowhere near the real resolution my screen can handle, but for emergencies, this is definitely sufficient. For completeness, these are the entries for nvidia: ==== $ dmesg | grep -i nvidia [ 11.222893] nvidia: loading out-of-tree module taints kernel.
