 |
|
Hi
I have an old GPU (Quadro FX 4800) which can't use the newest nvidia drivers.
What always worked for me was to use nvidia-drivers-340.107-r1.
After installing the new kernel (linux-4.19.57-gentoo) i reinstalled the above version of nvidia-drivers, and wanted to do 'modprobe nvidia' (as described in the wiki) but there seems to be no module: | Code: | $ sudo modprobe nvidia
modprobe: ERROR: could not insert 'nvidia': No such device
|
The modules for the old kernels are still around: | Code: | locate nvidia.ko
/lib64/modules/4.14.65-gentoo/video/nvidia.ko
/lib64/modules/4.14.83-gentoo/video/nvidia.ko
/lib64/modules/4.9.95-gentoo/video/nvidia.ko
|
but the one for kernel 4.19.57 are missing.
How can i fix this?

Did you rebuild locate database after installing drivers? Anyhow, your error is "no such device", to me it tells the module is found, but it can't find your nVidia card. Possibly because something else grabbed it. I'd look into dmesg for further clues.

| Does /usr/src/linux point at the newest sources? |

Thanks for your input.
Indeed, while /usr/src/linux pointed at the correct directory, 'uname -a' showed the old 4.14 kernel as being used.
The problem was of course that i had forgotten to update grub.
So after doing | Code: | sudo grub-mkconfig -o /boot/grub/grub.cfg
|
and rebooting, the nvidia-drive worked and X was started. |
