@koba, Funny you should mention that. I actually did yesterday try the 5.6.0-1032-oem kernel because that is the one that this machine was apparently certified under as documented here: https://certification.ubuntu.com/hardware/202010-28315
And, sure enough, suspend mostly works under this kernel. Or, at least, it properly wakes from suspend. I was not able to install linux-image-unsigned-5.10.0-1027-oem because it is not yet available in the respositories (even after 'apt update') but I installed linux-image-unsigned-5.10.0-1026-oem and I *am* able to reproduce the problem under this kernel. When I tried to resume from suspend, the mouse cursor was visible against a black screen and the machine was frozen. I restarted by holding down the power button and booted back into 5.6.0-1032-oem and ran journalctl -k -b -1, which I've attached. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1928593 Title: Dell Precision 3560: system hang upon resume from s2idle suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1928593/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
