Ubuntu Suspend Solution Fix blank screen laptop/computer won't come back
Even in new versions of Ubuntu this happens but for me I found out it was because of one feature under "Power Management".
I had "Spindown hard disks when possible" ticked, after disabling that, my computer wakes up from suspension every time now. So if your computer won't unsuspend with any version of Ubuntu/*Nix try disabling the spin down hard disk option as it's obviously the culprit for many situations.
