I have gone to great lengths to appease Nvidia Drivers. The following does not produce a console on my hardware
set linux_gfx_mode=text
export linux_gfx_mode
menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-f47d27d1-2d39-4f88-8ecc-cc26d7ab51cc' {

gfxmode $linux_gfx_mode
insmod gzio
if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
insmod part_gpt
insmod ext2
set root='hd0,gpt4'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt4 --hint-efi=hd0,gpt4 --hint-baremetal=ahci0,gpt4 6999d3cd-e1c1-4938-8930-10fe35a36b34
else
search --no-floppy --fs-uuid --set=root 6999d3cd-e1c1-4938-8930-10fe35a36b34
fi

}
this still yields the infamous

No. It’s a grub thing. Grub allocates a framebuffer and you either have to preventi it from doing so or make it release it again.

“it just works”
The behavior is undefined. It works until it does not.

there is literally no combination of vesa/uvesafb/vesa off console=text that works in any case
See the archlinux link. It’s a grub thing.

never not throw that error when using UEFI and Nvidia linux :(
I won’t believe there’s an UEFI that keeps a framebuffer open after its init job is done until I see one ;-P
I yield to hivemind’s superior grub wrangling, I saw another post where the moderator only said “your probably in the clear” Then this is a bug.
If you’re booting in native UEFI mode, you will always have efifb loaded. Otherwise there’s no console at all, just a blank screen. But, as the warning clearly says, Nvidia only supports a VGA console. Which consequently means native UEFI is not supported, you need to boot in BIOS compatibility mode.
Yeah, this is clearly something Nvidia will need to work on, considering UEFI is now the norm. But as it is, the warning says there might be corruption, so it’s not surprising that there’s corruption. So you’ll have to boot in BIOS compatibility mode until Nvidia officially supports native UEFI.
So I installed linux via efistub this is still in dmesg

The warning will always be there, because efifb is, no matter which loader is used. vekin is merely saying it works for him. It works for a lot of people without any instability of corruption. On my old BIOS system I used vesafb with the nvidia blob, no problems ever. But that’s by chance, not by design.
The message is a little misleading in UEFI mode. What it means it that the GPU was initialized to a graphical mode using the legacy VGA BIOS, regardless of whether the system was booted in UEFI mode or not. Typically this happens if the Compatibility Support Module (CSM) is enabled in the system BIOS. If you have an option to disable CSM in the SBIOS, please try that.

UEFI Stub, CSM Full Disabled
Could it be that I’m using Other OS in secure boot and an unsigned kernel because I am going to try that next :(
What graphics card are you using? If it’s not fairly recent then it might predate the signed GOP driver that’s included in the VBIOS in recent cards.
It’s interesting how recent this thread is, gien how many threads there are about the error message all over the internet for years.
I’m typing this on a white plastic iMac. Whatever typos there are is due to display lag. This hardware is nearly a decade old, UEFI is not exactly new. nVidia, just open source it.
BTW, if anybody could give me an idea how to improve display performance on said iMac with its unsupported GeForce 7300 GT, I’m all ears. Certain programs (Chromium) are unusable due to video lag, others are fine.
Been having issues with KDE sleep corruption forever, I have had Nvidia 660GTX, and now 760GTX, using drivers 304->349 both experienced the same issue with screen corruption after sleep in KDE.
Saw this error a long time ago and assumed it was safe to ignore since you cannot boot EFI without the EFI framebuffer…
Changing my boot setup from EFI Stub kernel to MBR Bios boot with grub and using the /etc/default/grub config as specified by the OP fixed corruption after sleep in KDE and removed the dmesg error for me.
this seems to be highly system firmware dependent. On my dell I don’t have any problems with UEFI and the nvidia driver, I even get the “standard” text console with the kernel’s builtin simple framebuffer driver. Suspend/resume do work as well, the only “issue” I have is that on resume there’s random garbage on screen for a split second until the kde lock screen appears.
Like someone said before, not all cards support fully UEFI boot. I got Zotac 760 where it will display this message because it cannot boot fully in UEFI mode. However switching to 970 this error message wont show up.
I know that MSI had on their forums a rep where you could ask for a updated BIOS for your card and they would give you the instructions on how to flash and provide you with a BIOS file.
I’m not usually one to necropost old threads, but because it might be helpful to others, disabling CSM removed the message and seems to have fixed my graphics corruption problems. In my UEFI, CSM was automatically enabled in every mode except Normal Boot (Fast Boot, Ultra Fast Boot) and further the setting was hidden from me until I tried normal mode!
I selected normal mode in my ASRock UEFI, and then CSM appeared (showing enabled as the default) to finally give me the option of disabling. It might be helpful if the error message was updated to suggest that CSM might lead to a BIOS mode boot with some firmwares (and subsequent corruption in some cases).
Here’s hoping my necropost wasn’t too ignorant or offensive. Your post was extremely helpful.
