I saw a thread on Reddit where Thinkpad users (with Intel processors) also had difficulties with laptop resuming from sleep. I guess it’s time for an Intel version of my article.
Fix suspend and resume
to find your kernel version, type
For kernel 5.19, 6.0 and newer
On a GRUB system
If your system uses GRUB, edit the /etc/default/grub file. On the following line :
add the following :
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash <put parameter here>"
This part can vary a lot between distributions, apply the changes with the following:
grub2-mkconfig -o /boot/grub/grub.cfg
grub-mkconfig -o /boot/grub/grub.cfg
On a SYSTEMD-BOOT system
edit your config file, it could be any of the following:
Note: on PopOS! the file is called : /boot/efi/loader/entries/Pop_OS-current.conf
If you still can’t find it, try with this:
sudo find /boot -iname '*.conf'
In your file you should see something similar as :
options root="LABEL=arch_os" rw
add the new option before the last double quote, like this:
options root="LABEL=arch_os" rw <put your parameter here>
Note: on PopOS! it will look like this, add the intel_iommu=igfx_off after ro.
options root=UUID=... ro intel_iommu=igfx_off quiet loglevel=0 systemd.show_status=false splash
