Dumping a bit more debug log before I forget: I disabled NVIDIA from the software & updates. If I try to suspend:
- it immediately wakes up into lock screen - I can't login anymore: after password, goes into black kernel log screen as in boot That was in Wayland, the new default. So I blacklist wayland, reboot to X11, and now when trying to suspend: - it immediately wakes up into lock screen - but I can login Possible threads: - https://askubuntu.com/questions/1151709/suspend-not-working-in-ubuntu-18-04-and-19-04 - https://askubuntu.com/questions/1133919/ubuntu-18-04-2-immediately-wakes-up-from-suspend Notably https://askubuntu.com/a/1363662/52975 says CUDA might still be a problem! So I now purged Everything from NVIDIA, I noticed that I had nvidia-opencl-dev:amd64 installed ii, and the graphics stuff installed rc, and immediately after purge suspend works again on X11! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1953674 Title: Screen does not wake up from suspend/does not wake up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-470/+bug/1953674/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
