    Possible duplicate of Updated kernel to 4.8 now missing firmware warnings – WinEunuuchs2Unix Apr 07 '19 at 15:04
  • @WinEunuuchs2Unix don't know if it makes any difference, but OP is running 4.15.0-46. – heynnema Apr 07 '19 at 15:36
  • @heynnema These warnings first started with Kernel 4.8 release. At the time 4.8 was off-topic and the duplicate candidate was closed. The warnings continued with subsequent kernels after 4.8 and the duplicate candidate was re-opened. We will likely see these warnings for many years at this rate. With drivers missing there are certain Intel features you can't use. – WinEunuuchs2Unix Apr 07 '19 at 23:52
  • @WinEunuuchs2Unix as per my answer, doesn't reinstalling linux-firmware replace the missing files? Looks like it does to me. No? – heynnema Apr 07 '19 at 23:56
  • @heynnema I tried your answer early this morning and it doesn't work for kernel 5.0 but it is using newer Intel Drivers than the kernel 4.14 I booted with so it's not a complete test. I posted preliminary results in an answer below before this question gets closed... – WinEunuuchs2Unix Apr 08 '19 at 08:53

Just get the file from the kernel git:

git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

sudo cp ./linux-firmware/i915/icl_dmc_ver1_07.bin /lib/firmware/i915/icl_dmc_ver1_07.bin

NCLI

  • In my case I needed a different file sudo cp ./linux-firmware/i915/tgl_dmc_ver2_04.bin /lib/firmware/i915/ but the basic idea was correct. Thank you! – user207863 Jan 10 '20 at 18:34

    Just to save your data use --depth=1 for a shallow clone.

    git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git --depth=1

This answer appears to best solution for missing Intel Graphics Driver warnings:

As requested in comments it appears warnings do not go away with linux-firmware reinstall:

  • You installed an older linux-firmware 1.157.21. Newer versions do contain the required files, except for 1. – heynnema Apr 08 '19 at 13:24
  • On 18.10 w/4.18 kernel, linux-firmware 1.175.1 has all of the files that you show as possibly missing, except for icl_dmc_ver1_07.bin. With running kernel 5.0.1, the linux-firmware file you used was too old. So the Intel web site might be required in your case example. – heynnema Apr 08 '19 at 13:27
  • So it looks like my answer is correct... unless you're running with a rogue kernel :-) – heynnema Apr 08 '19 at 13:37

    With kernel 5.0.1 you may need to install this linux-firmware... https://packages.ubuntu.com/disco/linux-firmware – heynnema Apr 08 '19 at 15:08
  • @heynnema I'm not using 5.0.1 because it's missing DKMS support for various drivers I need. Although installed I've never booted it. The other kernels already had .bin drivers for Skylake, Broxton, Kabylake, etc. installed so there would be no warning messages. What I can do is rename the .bin drivers and then run linux-firmware reinstall to see if it installs them for kernel 4.14.110 which I'm running now. If it doesn't then it's back to the BLOB (Binary Large OBject) as the only way to install. As far as it being an older version, it was a fresh 16.04 install this year. – WinEunuuchs2Unix Apr 08 '19 at 23:19
  • I saw all of your update-initramfs output, and 5.0.1 was the only one that generated the errors. That's why I gave you the Disco link for the latest firmware. Why aren't you running with 18.04/18.10? Are you not going to do 19.04 later this month? What dkms drivers don't work with 5.0.1? – heynnema Apr 08 '19 at 23:37
  • I did a test deleting .bin in /lib/firmware/i915 and linux-firmware does the trick alright. I updated my old answer to save people time. I've tried 18.04 a few times but enjoy 16.04 Unity much better. I might wait for 20.04. I definitely don't do 15.04, 16.10, 17.04, 18.10, 19.04, etc. I spend most my time developing software and don't want to be distracted with new interfaces, gsettings or whatever. – WinEunuuchs2Unix Apr 08 '19 at 23:44
  • @heynnema I'm upvoting your answer. I will be deleting this answer soon since it was all about experimenting and fact finding with a whole bunch of comments thrown in which the mods hate (and rightfully so as they distract from the website). – WinEunuuchs2Unix Apr 08 '19 at 23:53
  • Looks like you need to update this answer also. You didn't say what dkms driver problems you had with 5.0.1. Lastly... 16.04 vs 18.04/10... Unity vs GNOME... not really that much GUI difference. The big difference is with netplan... a real PITA. – heynnema Apr 08 '19 at 23:53
  • @heynnema I don't remember which DKMS drivers weren't working for sure. I think it was nVidia 384.10 and nvhda (which is custom sound over HDMI on Optimus laptops with GTX 970M, 1060, etc where manufacturers power off the sound channel on boot). I think there is a DKMS for Virtual Box but I haven't used that since last year. Part of a project to record grub boot screen where I changed second to 1/10th of second for smooth circle progress countdown on Grub Graphics boot: https://stackoverflow.com/questions/51341871/finding-countdown-timer-in-grub-2-02-source-code/52138789#52138789. – WinEunuuchs2Unix Apr 09 '19 at 00:02
  • @heynnema With 1 second interval the grub countdown graphics make "big block" circles and you don't get smooth transition unless you modify grub to be 1/10th of a second. I don't get out much :P – WinEunuuchs2Unix Apr 09 '19 at 00:04
  • @heynnema I upvoted too soon. I deleted the kbl_guc_ver9_14.bin that OP was missing and linux-firmware doesn't add it back in. As Doug Smithies said in his post (https://askubuntu.com/a/811487/307523) Ubuntu tends to lag behind on drivers. So OP will have to download Intel BLOB as in my answer. – WinEunuuchs2Unix Apr 09 '19 at 00:11
  • You're probably still loading an old linux-firmware file. The 18.10 linux-firmware contains that .bin, as (probably) the disco version of linux-firmware link that I gave you. We've got to get you out of the 16.04 world... and into the 21st century my friend. – heynnema Apr 09 '19 at 00:14
  • @heynnema I think 2016 was in the 21st century :p. As far as whether or not OP needs to upgrade his linux-firmware to a different repository I can't say. But I downloaded the BLOB I deleted and everything is OK on my system now. I'm not keen on putting DISCO on top of XENIAL... – WinEunuuchs2Unix Apr 09 '19 at 00:19
  • I think that OP is running a newer kernel than you, so that version linux-firmware probably contains that .bin. Of course, you could download that linux-firmware and confirm that... :-) – heynnema Apr 09 '19 at 00:21
  • @heynnema I have no idea. Hopefully OP signs on soon and updates us. I've revised the answer with only the error OP and I both got. – WinEunuuchs2Unix Apr 09 '19 at 00:22

In terminal...

sudo apt-get install --reinstall linux-firmware # reinstall firmware

and

sudo pico /etc/default/grub # edit grub defaults

change:

GRUB_HIDDEN_TIMEOUT=0

to:

#GRUB_HIDDEN_TIMEOUT=0

Save file. Exit editor. (control-o, return, control-x)

sudo update-grub # update GRUB
