I just installed the latest desktop version of ubuntu 22.04 LTS jammy (I installed it next to the windows OS) and I'm running into this problem: everytime the computer goes on stand-by, he never wakes up. I have to turn it off by force (pressing the power button) and then restart from the beginning..

I found this question about this topic but I would kindly prefer if someone would check what I need to do before doing something wrong, since the version of ubuntu has changed and also my pc is different.

Here I copy some details (obtained using lshw command) of the computer I'm having troubles with:

  • description: Notebook
  • product: Inspiron 16 5620 (0B3B)
  • vendor: Dell Inc.
  • cpu
  • product: 12th Gen Intel(R) Core(TM) i7-1255U
  • vendor: Intel Corp.
  • display
  • description: VGA compatible controller
  • product: Intel Corporation vendor: Intel Corporation

(it should be an intel graphics iris xe but it is not written anywhere)

  • Proper support for Intel's 12th gen CPUs is in the works. You may have to wait for a newer kernel. – ChanganAuto Apr 27 '22 at 12:59
  • Thank you for your help, but what kernel you are referring to? At the moment I solved this problem installing the linux oem (I'm not really sure what it is) with the command sudo apt install linux-oem-22.04. Now it works properly but using inxi -G I get that I'm using as graphics "Intel driver: i915 v: kernel". Is this correct or not? – Gabrielekk Apr 27 '22 at 16:00
  • OEM kernels often provide hardware support that is absent from the regular versions. – ChanganAuto Apr 27 '22 at 16:02
  • @ChanganAuto Then so far what I did is good, isn't it? – Gabrielekk Apr 27 '22 at 16:03
  • Yes, of course :) – ChanganAuto Apr 27 '22 at 16:25
