I too am facing same issue with Asus expertcenter PN53. I tried to check if the suspend issue is present in my installation or even live disk has the same. It appears the issue is persistent across both.
Later I tried using ubuntu booted to tty2 without gdm3. suspend resume works perfectly fine. I tried exercising this cycle over 20 times, none failed. After this I logged into gdm3 from tty1 and tried running same command `sudo systemctl suspend` and it failed in first go. with journalctl -b-1 the last log i see is `kernel: PM: suspend entry (s2idle)` -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2067945 Title: Restart after resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2067945/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
