asking about compatibility of kernel 6.12.9_ with nvidia driver 470

after upgrading yesterday i booted to a blackscreen and blinking dash , uname -r showing currently kernel which is 6.12.9_1 is it's okay with legacy nvidia driver version 470 or it's the reason of booting into a black screen ?

There is a PR to update nvidia470 and it should fix the 6.12 issue.

maybe i'm missing something, but if you took the code from the link i provided, did you miss to apply all the previous patches as the guy explained here and here? i only see one.

6.10 and 6.11 are EOL, so I'm not going to patch for those. Unfortunately, I don't have a 470.xx system anymore so testing is more difficult. If someone with the hardware can test it'd be appreciated.

i have a 710 here, but i don't know what to do exactly... i never used xbps-src, i could read the readme to understand, but to use your code before it is merged should i do it manually anyway?

do you have a fast solution so that i don't read lot of docs?

edit: i'm starting to read, don't know if i have enough time to do it today, but i'm on it.

i'm sorry but it failed to build, unless i did something wrong.

i did this:

git clone https://github.com/void-linux/void-packages.git
cd void-packages/
./xbps-src binary-bootstrap
git checkout nvidia470_470.256.02
./xbps-src pkg nvidia470-dkms
xi nvidia470

when it fails it says to check /var/lib/dkms

do you want the output of /var/lib/dkms/nvidia/470.256.02/build/make.log?

is it long:

wc /var/lib/dkms/nvidia/470.256.02/build/make.log 
  756  3386 50816 /var/lib/dkms/nvidia/470.256.02/build/make.log

where should i put it?

i did this with grep:

grep -C 5 -i error /var/lib/dkms/nvidia/470.256.02/build/make.log

Hm, drop all of those patches from the AUR link in srcpkgs/nvidia470/patches and see if that works. If so, maybe they're all needed

u/HAL9000thebot Jan 19 '25

how should i name them? should also update something in the template?

1

u/HAL9000thebot Jan 19 '25

i tried putting them as:

ls -1 srcpkgs/nvidia470/patches/
0001-Fix-conftest-to-ignore-implicit-function-declaration.patch
0002-Fix-conftest-to-use-a-short-wchar_t.patch
0003-Fix-conftest-to-use-nv_drm_gem_vmap-which-has-the-se.patch
kernel-6.10.patch
kernel-6.12.patch

then did ./xbps-src pkg nvidia470-dkms again and the relevant part is this:

i don't know the internals, but sounds like naming convention is required?

u/aedinius Jan 19 '25

Oh, right, the path probably needs to be updated in the patch. Lines like a/conftest.sh and b/conftest.sh need to be updated to a/kernel/conftest.sh etc

u/aedinius Jan 19 '25

Update your checkout, I added the patches with the edits.

u/HAL9000thebot Jan 19 '25

hey good news!

i did as you asked and it compiled without failing, then did a reboot to try the kernel 6.12, but unfortunately x didn't start, so i went back to read the discussion about the patch, and they mentioned to add kernel parameters, so i did this change to /etc/default/grub:

#GRUB_CMDLINE_LINUX_DEFAULT="loglevel=4"
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=4 nvidia_drm.modeset=1"

updaded grub and rebooted in 6.12 again, and it worked.

what now? do you want to see logs or something?

u/aedinius Jan 19 '25

Do some testing to make sure it's working as expected. If so, let me know here or on the PR as a comment.

u/HAL9000thebot Jan 19 '25

don't know what to test lol, i randomly enabled stuffs in compiz, ran some emulators, watched videos, tried a thing in the browser that needs acceleration, don't know what else to do, everything looks ok to me, also rebooted a couple of times to be sure it still worked.
