Sorry for the noise but, I am having the very same problem with an nvidia card. I am posting this here because it seems that this problem affecting AMD, intel an nvidia cards since the 18.10 update, so maybe this should be inspected as a general graphics bug, not just a bug in AMD. If that is not the case, my apologies for adding a bit of noise.
In my case, I am seeing this error: Xan 30 12:43:54 boi kernel: nvidia-modeset: ERROR: GPU:0: Failed detecting connected display devices I will try disabling modeset in nvidia -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799964 Title: Ubuntu 18.10 After Blank Screen System Won't Come Back To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1799964/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
