[Bug 2031580] Re: Running Ubuntu 22.04 on a 2016 Macbook Pro and waking from suspend is now broken after running apt update && upgrade

[Steve Beattie]

Hey Steve, sorry you're having issues.

One thing that would be useful to know is which kernel versions you're
experiencing this under. I notice in the apt.log that when the newer
version of the intel-microcode package was removed, apt also removed the
meta packages for the linux-generic-hwe-22.04 kernel, which would not
have uninstalled the current 6.2.0 linux kernel, but it *will prevent*
apt from pulling future kernel updates for you, so you will want to
reinstall the linux-generic-hwe-22.04 package.

One possible cause of this issue might be that the 22.04 kernel moved
recently from being based on the upstream 5.19 kernel to the 6.2 kernel.
If you still have 5.19 kernels installed, you might try rebooting into
one of those and seeing if the waking from suspend issue is a problem
there, too. To do that, you'll need to get into the grub menu on boot,
and select an older kernel to boot into. You may need to modify in
/etc/default/grub the GRUB_TIMEOUT_STYLE setting to menu and to set the
GRUB_TIMEOUT value to a non-zero value, running sudo update-grub after
making your edits.

Title:
  Running Ubuntu 22.04 on a 2016 Macbook Pro and waking from suspend is
  now broken after running apt update && upgrade

Status in intel-microcode package in Ubuntu:
  Invalid

Bug description:
  Disabling Wayland partially helps but eventually will cause the
  computer to not wake up. This occurs both when closing the lid and
  when leaving the computer idle for some time.

  Description:	Ubuntu 22.04.3 LTS
  Release:	22.04

  intel-microcode:
    Installed: 3.20230808.0ubuntu0.22.04.1

  I expected resume from sleep/suspend to behave as it did prior. If I
  would open the lid or push any keys, the computer would wake up from
  sleep/suspend.

  Instead, the computer does not wake from sleep/suspend and I need to
  force the computer to shutdown using the power button and then turn it
  back on again.
