Ubuntu 18.04 won't work with i9 9900k integrated graphics

Question

I've had to remove my graphics card for some time and I've just connected my screen to the Gigabyte Z390 AORUS Pro motherboard output HDMI. But I can't change the monitor resolution to 2k (1440p), even though the Gigabyte spec states the onboard graphics has 1 x HDMI port, supporting a maximum resolution of 4096x2160@30 Hz, Support for HDMI 1.4 version and HDCP 2.2, and the CPU's specs for UHD630 graphics onboard calls for 4096x2304 .

I've followed steps here but it's not working, just changed the Login screen to 2k resolution.

Also I've copied the bin that describes this post, without any result.

Some outputs from related commands.

In my Windows partition, all works perfectly without any configuration so I suppose that all is OK in BIOS configuration.

First, I would try different screen frequencies; what are you running the screen at now? Then, since Gigabyte does not support Linux, I would try generating LiveUSB flash drives with Ubuntu 19.04 https://ubuntu.com/download/desktop, Ubuntu Budgie 19.04 https://ubuntubudgie.org/downloads, Ubuntu MATE 19.04 https://ubuntu-mate.org/download/, Kubuntu 19.04 https://kubuntu.org/getkubuntu/, Lubuntu 19.04 https://lubuntu.me/downloads/, and Xubuntu 19.04 https://xubuntu.org/download/ to see if booting with a different kernel lets you get to 1440p. — K7AAY, Jul 24 '19 at 16:32
Kernel 5.1 probably will not help. I'm using 5.1.16 and I'm having analogous problem with my iy-8750H and GTX1050Ti/intel 930. It doesn't see external hdmi with i915 card. However it worked smoothly with older Ubuntu (ex. original 18.04 without any updates). — user2707175, Aug 03 '19 at 20:39

Finally I installed Ubuntu Budgie 19.04 as @K7AAY recommended and all works fine.

So, it's something specific to Ubuntu 18.04 which uBudgie 19.04 does not use. – K7AAY Jul 25 '19 at 21:43
