--- Comment #59 from Luca T. (luca.trombin@gmail.com) --- (In reply to luminoso from comment #57)
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,
it works greatly, thanks a lot!!!
I read about this switch but I lost the patience to try and retry, but you saved my life! :)
Thank you so much,
Luca
