 Posted: Mon Mar 17, 2025 1:20 am Post subject: No video output w/ nvidia-drivers 570 |
 |
|
Summary: No video output w/ nvidia-drivers-570.124.04 and kernel 6.12.16.
Details: I have an Nvidia GeForce RTX 3060, which I've been successfully using w/ kernel 6.12.16 and x11-drivers/nvidia-drivers-550.144.03. Normally I boot to console, then manually start a Wayland DE, e.g. KDE (dbus-run-session startplasma-wayland).
Today I upgraded to nvidia-drivers-570.124.04, then rebooted. I saw the normal first few messages in the console, but w/in a couple of seconds, the screen went black. Using the keyboard, could log in and start a Wayland DE, but still no video output. I SSH'd in, rebooted, and selected an older kernel in GRUB, 6.6.74. This kernel was still able to use the modules from the older nvidia-drivers-550.144.03, so I got normal console output and was able to start a DE. Of course, reverting to the older nvidia-drivers (550) fixes it.
I thought the changes to /etc/modprobe.d/nvidia.conf might have been the problem w/ 570:
| Code: |
# Kernel Mode Setting (notably needed for fbdev and wayland).
# Enabling may possibly cause issues with SLI and Reverse PRIME.
options nvidia-drm modeset=1
# If modeset=1 ^, NVIDIA will handle the console/tty display and
# allow overriding DRM devices such as simpledrm. This is a default
# since 570.x drivers but has been known to cause a variety of
# problems. Given efifb is more typically used on Gentoo at the moment,
# it is not *required* here and is safer to be disabled for now.
# Comment out the line if you need it. https://bugs.gentoo.org/949097
options nvidia-drm fbdev=0
|
The 1st option is correct; I pass that option to the kernel using /etc/default/grub:
| Code: |
GRUB_CMDLINE_LINUX="nvidia-drm.modeset=1"
|
I thought maybe the 2nd option was causing the issue, so I set fbdev=1 and rebooted, but that didn't change anything, still no video output.
dmesg output doesn't look super interesting:
| Code: |

|
The only difference between dmesg output for different nvidia-drivers versions is that version 570 has the line "Loading firmware: nvidia/570.124.04/gsp_ga10x.bin". Can get rid of that by uncommenting the "options nvidia NVreg_EnableGpuFirmware=0" line in /etc/modprobe.conf/nvidia.conf. I tried doing that, but still no video output.
I have the usual kernel options set. Here are some -- not sure which other ones might also be interesting:
| Code: |
CONFIG_SYSFB=y
CONFIG_SYSFB_SIMPLEFB=y
CONFIG_DRM_FBDEV_EMULATION=y
CONFIG_FB=y
CONFIG_FB_EFI=y
CONFIG_FB_SIMPLE=y
CONFIG_DRM=y
CONFIG_DRM_FBDEV_EMULATION=y
|
Anyone have any ideas?

Hi jimbotronic!
Same problem as you; if I accept the suggested world update from
x11-drivers/nvidia-drivers-565.57.01-r2
to
x11-drivers/nvidia-drivers-570.124.04
Upon rebooting, I get a black screen when graphical mode starts.
I've also tried un-commenting the line
options nvidia NVreg_EnableGpuFirmware=0
in
/etc/modprobe.d/nvidia.conf
and like you, that didn't help.
More precise system info:

I have x11-drivers/nvidia-drivers-570.124.04 working, with firmware loading using the unmodified distkernel sys-kernel/gentoo-kernel-6.12.16.
For comparison, the above in the distkernel are: | Code: |
CONFIG_SYSFB=y
# CONFIG_SYSFB_SIMPLEFB is not set
CONFIG_DRM_FBDEV_EMULATION=y
CONFIG_FB=y
CONFIG_FB_EFI=y

Hi Kaitain,
My config values are the same as yours (for the keys you listed)
| Quote: | CONFIG_SYSFB=y
# CONFIG_SYSFB_SIMPLEFB is not set
CONFIG_DRM_FBDEV_EMULATION=y
CONFIG_FB=y
CONFIG_FB_EFI=y
# CONFIG_FB_SIMPLE is not set
CONFIG_DRM=y
CONFIG_DRM_FBDEV_EMULATION=y |
So it might be some other key that makes a difference? |

Kaitain,
Thank you for your efforts, but even adding the kernel boot options doesn't help:
Taken from dmesg:
| Quote: | [ 0.000000] Linux version 6.12.16-gentoo (root@machine) (gcc (Gentoo 14.2.1_p20241221 p7) 14.2.1 20241221, GNU ld (Gentoo 2.44 p1) 2.44.0) #3 SMP PREEMPT_DYNAMIC Sat Mar 29 17:24:40 EDT 2025
[ 0.000000] Command line: BOOT_IMAGE=/boot/kernel-6.12.16-gentoo root=PARTUUID=<numbers> ro nvidia_drm.modeset=1 nvidia_drm.fbdev=1 |
I'll try comparing your kernel config to mine. Although we are using the same kernel version, I have manually configured mine, so there might be some differences there... |

Do you have any better success with USE=“kernel-open” emerge nvidia-drivers ? Both worked for me, but the open driver seems to sit better with my laptop (slightly smoother desktop animation, and made screen recording artefacts a little less severe)

I suppose it's back to first principles, then - is there anything in the wiki that you've deviated from over the years: https://wiki.gentoo.org/wiki/NVIDIA/nvidia-drivers
If you're using an initramfs - any chance the old modules could have been pulled into it?
Maybe try emerging the dist-kernel and trying with that, then chop out the bits you don't want once it's working?

You're right about the principles of investigating, Kaitain.
Only I wonder if it isn't just better to try out the nouveau driver instead.
I have a machine running Gentoo with an nvidia GK107 [GeForce GT 740], which has long ago stopped being supported by nvidia, so I had to move it to nouveau. It has a different problem of having a bright green screen when it switches to graphics mode, which appeared sometime after kernel 6.6.74, but if I find that nouveau supports the GA106 [Geforce RTX 3050] properly, I'll just switch to that and be done with the hassle.
Ultimately, I just want a machine that works, and don't have a ton of time to figure out all these weird issues. |

I'm having the same issue. It's a 1030 card. But to recap:
WAS running 6.6.74 kernel with nvidia-drivers-570.133.
BUT needed to change the kernel config for <reasons>
So, configured 6.12.21 for the <reasons> and rebooted.
Mistake #1: never change two things at once.
Reboot into 6.12.21 console, all good (I use startx). Recompile nvidia-drivers - no bueno.
Now I'm stuck at the text console with no cut and paste trying to find what went wrong.
In fact what is missing is now CONFIG_DRM_TTM_HELPER this is where it gets interesting.
CONFIG_DRM_TTM_HELPER can't be enabled directly, it can *only* be enabled indirectly by selecting a kernel drm driver.
So I picked one: nouveau.
Mistake #2: Never use nouveau.
So I recompiled the kernel with nouveau and rebooted, recompiled nvidia-drivers, that worked and started X.
Black screen. Completely unresponsive. So. I have to find my laptop, but of course its battery is flat, find the charger <etc>
ssh in and reboot. Back to 6.6.74. where I can start X and do some research. Hey I could try ChatGPT,
Mistake #3: Don't blindly trust ChatGPT.
ChatGPT told me to turn on CONFIG_DRM_TTM_HELPER, which of course you can't without a kernel driver. But did helpfully give me a number of other config options to make sure I had turned on.:
| Code: |
CONFIG_DRM=y
CONFIG_DRM_KMS_HELPER=y
CONFIG_DRM_FBDEV_EMULATION=y
CONFIG_DRM_TTM=y
CONFIG_DRM_TTM_HELPER=y # (this is auto-selected by DRM_TTM)
CONFIG_FB=y
CONFIG_FB_EFI=y # optional, useful for EFI systems
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_MTRR=y # recommended on x86 for NVIDIA
|
And confirmed my mistake above, don't ever mix nouveau and nvidia-drivers in any way. So ChatGPT suggested I turn on Bochs, which is also useful for QEMM:
| Code: |
CONFIG_DRM_BOCHS=m # this pulls in DRM_TTM_HELPER safely
|
just tomake sure, blacklist both it and nouveau thusly:
| Code: |
# /etc/modprobe.d/blacklist-drivers.conf
blacklist nouveau
blacklist bochs_drm
|
(optional, I haven't done this yet) and make sure that the other kernel gpu drivers are not installed:
| Code: |
# CONFIG_DRM_NOUVEAU is not set
# CONFIG_DRM_RADEON is not set
# CONFIG_DRM_AMDGPU is not set
# CONFIG_DRM_I915 is not set
|
On recompilation I now got:
| Code: |
depmod: WARNING: /lib/modules/6.12.21-gentoo/video/nvidia-drm.ko needs unknown symbol drm_client_setup

This is correct: I'm recompiling kernel 6.12.21 using kernel 6.6.74, and that symbol doesn't exist in the running kernel when modules_install tries to DEPMOD the new modules. It's a good sign.
It wants me to reboot before compiling nvidia-drivers, but I've had my fill of compiling kernels from the console (with no google or AI available) for today. The target system and the running system don't have to match.
Recompile nvidia-drivers, reboot, everything works.
Now I can go back to what I was doing two hours ago. Lesson learned. This was going to be a dogs breakfast regardless. the combination of the 570 and 6.12 upgrade paths probably out a lot of nvidia owners into a kernel compile and crash loop with no obvious exit point. I wish I had had some kind of warning.
At least I'm out of it. Hooray! I hope this helps you guys.
Cheers,
Jon. |

Very interesting read. Thank you.

Not sure about this, but I've had similar problems in the past and the solution was to do a make clean and then make
Sometimes when changing things back and forth, it can result in some objects getting linked that should not be there.
Also, were you eventually successful or not? Your post begins by saying you are having the same issue, but at the end it could be read that you solved the problem? Did you?

I had similar problems.
My solution: I installed gentoo-kernel-bin and after booting and confirming that this is indeed kernel config problem I made sure both .config files match in the "Device Drivers/Graphics Support" section.
Hope this helps.
My modeset and fbdev options are both set to 1 in modprobe and kernel command line config files. |
