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 Kernel Packages, which is subscribed to nvidia-graphics-drivers-470 in Ubuntu. https://bugs.launchpad.net/bugs/1953674 Title: Screen does not wake up from suspend/does not wake up Status in nvidia-graphics-drivers-470 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-510 package in Ubuntu: New Bug description: After upgrading to 21.10 from 21.04 this problem started happening. It does not happen every time I suspend, and it usually happens after suspending for a longer time. After suspending for a longer time, it tends to happen most of the time. I can SSH into the computer, so it is just the display that is not turning back on correctly.
