For users still facing this issue, I workaround it with this: https://github.com/aelveborn/vgaswitcheroo-systemd
Basically before suspending it restores the GPU powerstate and resumes it once coming from a suspend state.
Never had problems again.
Hi Luminoso,
Thanks a lot, I'll try it out and let you know.
Thanks,
Luca
