Suspend not working?
We have packaged a small script to append a few parameters to the GRUB configuration that'll enable suspend on boot. There is also a hook to re-add the parameters should a GRUB update ever result in the parameters being lost. This was packaged for Linux Mint 22: Download Link

Manual method (the settings may be lost when security updates are applied, though rare):
1. After installation open a terminal window and gain admin access (click activities or your menu and search for / go to terminal):
Once at the terminal and (or in the chroot environment enter the following command):
nano /etc/default/grub
3. Find the line that reads ‘GRUB_CMDLINE_LINUX_DEFAULT‘ and append ‘ acpi_osi=! acpi_osi=Linux acpi_backlight=native’ to the end (without the quotes)
Save it, to save the file: CTRL+X, Y, ENTER
4. Now, update your grub file and reboot.
update-grub
reboot

Getting graphics working on Linux-libre distributions such as Trisquel
On systems that use a Linux-libre kernel the below disables the attempted loading of graphics firmware and gets 3d acceleration working. Just add the below line to grub. See directions above on how to do that.
i915.enable_guc=0
GNU Guix
For graphics and power management (ie make shutdown work, etc) add the following to the menu entry section just after quiet /boot/grub/grub.cfg:
acpi_osi=! acpi_osi=Linux’ i915.enable_guc=0
