Fedora & Intel Coffee Lake GPU driver

iNine · 01-06-2019, 05:18 AM

Hello.

I would like to gain more help from here since I found nothing as a perfect solution to my issue.

Fedora 27 is installed to my PC.
My PC configuration is;
- Intel Core i7 9700K CPU
- Z390 chipset motherboard

And I would not love to stick with 4.13.9-300 version.
4.20 version is installed.

With kernel 4.20 version.
Intel UHD graphics 630 is not working as it should. But;
1. Monitor can be unplugged and plugged in again.
2. Screen resolution is matched to the screen (2560x1080, using ultra-wide screen with DP connection.)
3. From GNOME, Setting > Details > About > Graphics : "unknown". Not even show "LLVM" or else.

After I checked "dmesg | grep -i i915".

Code:

[   28.401465] i915 0000:00:02.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=io+mem:owns=io+mem

Seems like "kbl_dmc_ver1_04.bin" is not found.

Should "kbl_dmc_ver1_04.bin" be placed in "/lib/firmware/i915/"?
I downloaded from Git and put into "/lib/firmware/i915/".
<The newest file.>

I'm not so sure what to fix and where to place the missing file.

Please guide me.
Thank you.

Welcome to the forums!

Unfortunately, Fedora 27 is "end of life" meaning it is no longer receiving updates and will never have hardware support for the latest generation (like your Coffee Lake GPU).

https://fedoramagazine.org/fedora-27-end-of-life/

I recommend to create a Live USB of the current Fedora 29 and take it for a test drive. If, in your tests, Fedora 29 has better support for your GPU than Fedora 27, then you know it is a good time to upgrade.

Thank you for your reply.
I just forgot to explain more that I tried Fedora 29 and found that it is not going to boot(halt while booting).

Couples hours ago, I did some test on CentOS 7 running on kernel 3.10 version.
LLVM 6.0 appeared as the graphic adapter.
And after I installed kernel 4.20 version, LLVM 6.0 still appeared as the GPU.
The same "dmesg" showed exactly the same. (As the fedora that installed 4.20 kernel above).

What exactly means?

What is output running in Xterm:

Code:

inxi -Gxx

i915 is the kernel driver, not usually a problem if the problem is in X. If xorg-x11-drv-intel is installed, remove it. The intel driver last had an official release nearly 4 years ago. Intel on Kaby Lake 630 works fine for me with 4.19 on openSUSE on the modesetting driver provided by the X server, which is where paid-by-Intel driver writers have been putting in most of their time.

Now, I moved to openSUSE Leap 15.0 and install 4.20 kernel.

Is "xorg-x11-drv-intel" equivalence to "xorg-x11-driver-video"??
I found this from using Yast2 > Software Management and it was removed.

I also made a search using "Intel" keyword.
Found "intel-vaapi-driver" installed as default.
Do I have to remove it?

inxi -Gxx output:

Code:

Graphics:  Card: Intel Device 3e98 bus-ID: 00:02.0 chip-ID: 8086:3e98
           Display Server: wayland (X.org 1.19.6 ) driver: i915
           tty size: 80x24

Currently, by using 4.20 kernel and remove "xorg-x11-driver-video", my graphics appears "llvmpipe (LLVM 5.0, 256 bits)"

I may not understand your suggestion in some points because I'm pretty new to fix the GPU driver in Linux.
Step-by-step explanation to fix may make me go to the point a lot more easy if you are kind to...

Thank you.

No. xorg-x11-driver-video is a metapackage that provides all xf86-video-* packages. Upstream names the Intel X driver xf86-video-intel, which is the name openSUSE uses, while Fedora renames it xorg-x11-drv-intel.

I don't have it, so I do not think you need it either. Removing it will only save a small amount of storage space.

I expected more information, but didn't know you are using Wayland, which I cannot help anyone with. I use Xorg but not Gnome:

Code:

# inxi -GxxS

           direct render: Yes

If you use an Xorg session instead of Wayland and run inxi -Gxx again it would help us help you. If using Gnome now, at the login greeter choose an IceWM session instead to use Xorg and get the inxi -Gxx information.

LLVM means Low Level Virtual Machine. That's all I know about it.

Is package kernel-firmware installed? If so, what version is it? If 20180525 possibly you need a newer version for Coffee Lake. You could try installing this one:

Code:

sudo zypper in http://download.opensuse.org/tumbleweed/repo/oss/noarch/kernel-firmware-20181218-1.1.noarch.rpm

I still do not understand what is going wrong that you need to fix.

From your suggestion, I will try to follow and fix. If there's something get stuck, I will make a reply.

My target is to make graphic hardware acceleration works as it should because now the system only works by software rendering which consumes CPU usage and graphics is not smooth at all.

Thank you for your reply.
