The difference between state 1 and 2 is likely the PCIe port (to which the card is attached) being turned off or not from what I understood of all this.
And yes, the issue is about powering on the card again, nouveau has issues setting the card configuration correctly at this stage. Going off is working, but on not, resulting in lockup (at worse) or (partially) unusable card. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1803179 Title: System does not reliably come out of suspend To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1803179/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
