[SOLVED] Trouble installing driver

zavmat · 06-26-2019, 03:27 PM

Hello, I'm trying to update my driver's following the guide here https://www.if-not-true-then-false.c...-nvidia-guide/

I'm at step 2.8.5
And got:
Failed to run `/usr/sbin/dkms build -m Nvidia -v 390.116 -k 5.1.11-300.fc30.x86_64` Error! echo your kernel headers for kernel 5.1.11-300.fc30.x86_64 cannot be found at /lib/modules/5.1.11-300.fc30.x86_64/build or /lib/modules/5.1.11-300.fc30.x86_64/source

I've cd'd to /5.1.11-300.fc30.x86_64
Build and source are listed in red but I can't cd into them, no such file or directory.
Any help is greatly appreciated!

What distro of Linux are you running? Most have these drivers in the package management system (with some exceptions) and that is generally the preferred way of installing Nvidia drivers, not the way you are attempting.

Fedora 30 that sounds much easier, I just googled how to install graphic driver and this guide came up, I was thinking there should be an easier way than this

When googling how to do something in Linux, always preface your searches with the distro and version you are running, otherwise you will not get accurate results.

What is the specific problem you are hoping to solve by doing this?

Fedora supports many Nvidia cards "out of the box" with the open source Nouveau driver.

A good first step is to identify your specific card with:

Code:

lspci |grep -E "VGA|3D"

The error message suggests you're missing the kernel headers, which you can install with:

Code:

sudo dnf install kernel-headers

(Your tutorial covers this in step 2.5 "Install needed dependencies"---did you skip this step?)

So the problem is that images flash across the screen with a horizontal crack if that makes any sense. When I move a window around it's the same effect like the refresh rate is noticeable in that spot. I figured it was a graphical problem.

I did 2.5 I even double checked, and it said already installed. Let me try what you suggest, fingers crossed

zavmat · 06-26-2019, 04:12 PM

Still the same error I'm afraid

Looks like Fedora 30 is up to kernel 5.1.12 now. Try a full software update and reboot, then try again?

Personally, I have had good luck in the past with the rpmfusion method (but I am hesitant to recommend your 'switching gears' at this point, since you already got so far with the other method): https://rpmfusion.org/Howto/NVIDIA

It would be helpful if you told us which card model you have.

Let me give it a shot, it's a GeForce GT 630m

snowday · 06-26-2019, 06:03 PM

The next thing you want to check is whether your GT 630m is an example of "optimus" technology.

Code:

lspci -vnn | grep '\''[030[02]\]'

If you see two cards, one Nvidia and one Intel, then you probably have Optimus. When I run this command on my Dell laptop, I get this output, indicating I have Optimus:

Code:

00:02.0 VGA compatible controller [0300]: Intel Corporation HD Graphics P530 [8086:191d] (rev 06) (prog-if 00 [VGA controller])
01:00.0 3D controller [0302]: NVIDIA Corporation GM107GLM [Quadro M1000M] [10de:13b1] (rev ff) (prog-if ff)

The following tutorial has worked for me on my (slightly different than yours) Optimus laptop. Your mileage may vary.

(If it turns out you do not have Optimus, then please disregard.)

zavmat · 06-26-2019, 06:07 PM

I do have Optimus, I just ran the update and am trying again. It worked!thanks you guys for all your help!

Any clue as to why the screen was jagged at parts like that?

snowday · 06-26-2019, 06:22 PM

I think you might be describing a phenomenon called "tearing"? It happens when the frame rate of the graphics card is out of sync with the display.

If you watch this video, and the vertical lines appear jagged (the tops don't line up with the bottoms) then you have "tearing":

I'll be sure to test that as soon as I can get on, it won't boot now, it's stuck on starting network name resolution
