My dmesg says :
Code:
[    0.000000] Command line: BOOT_IMAGE=/vmlinuz-4.19.37-gentoo root=UUID=bda16273-fc1d-4b10-be26-9e14bde5064b ro quiet acpi_osi=Linux acpi_backlight=vendor pcie_aspm=force i915.i915_enable_rc6=1 i915.lvds_downclock elevator=noop vt.default_utf8=0

[    2.381332] i915 0000:00:02.0: fb0: inteldrmfb frame buffer device

I think this says I can't load the driver :
Code:
[    1.133677] i915 0000:00:02.0: Direct firmware load for i915/glk_dmc_ver1_04.bin failed with error -2

But this one contradicts that :
Code:
[    1.159370] [drm] Initialized i915 1.6.0 20180719 for 0000:00:02.0 on minor 0


What's actually happening here?

And one more thing. Am I using the right driver? I have Pentium N5000 with UHD 605. It belongs to geminilake so I thought "glk" in
Code:
i915/glk_dmc_ver1_04.bin
says "Geminilake". Is that right?

Here's my full dmesg just in case : https://pastebin.com/EZFfSVzC

gaurav712,

You have i915 built into your kernel. It needs i915/glk_dmc_ver1_04.bin available when it starts, so it needs to be in the kernel binary too.
With the firmware missing, you have missing functionality.
Code:
Disabling runtime power management.
at least.

Only part of the driver loaded. Its enough to get an image on the screen.

Code:
[    4.202874] EXT4-fs (sda4): mounted filesystem with ordered data mode. Opts: (null)

That is root being mounted read only. At that time, /lib/firmware can be read but its too late, i915 has already initialised.
