So, after installing Ubuntu, I was having problems with the Plymouth splash screen- it was not showing up during booting, nor when I shut my PC down. Sometimes it did show, but very rarely and only for a sec!

Then I found this link to a post who had similar problems; I myself have an Intel built-in graphics card, so followed the instructions given in that post(this one), and my problem has now been resolved...

But during the troubleshooting, I got some warning/error messages that shows something like this:

sudo update-initramfs -u
update-initramfs: Generating /boot/initrd.img-4.10.0-28-generic
W: Possible missing firmware /lib/firmware/i915/kbl_dmc_ver1_01.bin for module i915

What's with this missing firmware? I got the same message for some other commands too while troubleshooting Plymouth...

If anyone could clarify why this message is showing up I would very much appreciate it...

Thanks in advance...

Do you have an intel graphics card?

This message means that a kernel module (i915) need a firmware file, but it can't find it.

If you do not use the i915 module or your graphics card does not use this particular firmware, you can ignore the error.

  • You said If you do not use the i915 module or your graphics card does not use this particular firmware, you can ignore the error. How can I know if I'm using the module or my graphics card is using the firmware? – Apollonius Sep 22 '17 at 7:51
  • what card do you have? If it was needed you'd get an error on boot – ravery Sep 22 '17 at 7:53
