Onboard intel graphics for Gigabyte B560M DS3H AC mother board not working in Ubuntu 20.04 or 20.10 getting only 1024X768 resolution

Onboard intel graphics for Gigabyte B560M DS3H AC mother board not working in Ubuntu 20.04 or 20.10 getting 0nly 1024X768 resolution. I am using intel core i7 11 gen 11700k processor, 32 gb ddr4 ram and onboard wifi and bluetooth. Except display drivers remaining all working. For Graphics issue followed all the solutions that I could see online. Nothing worked. Not able to play mp4 videos in browser. After doing 1 week of research, multiple installations found that Intel is providing UHD 750 graphics which need kernel 5.9 or higher. Also found that Intel did not release drivers for these graphics as of now.

$> sudo lshw -c video giving below output:

Solution 1:

My situation is similar to yours. I solved this problem by installing linux-oem-20.04b.

sudo apt install linux-oem-20.04b
