Hello Dan, Thanks for following up! To be 100% sure (and not wasting developer cycles), I reinstalled my system with Linux Mint 19.1. I had modified (too) many files trying to solve the problem, so better start clean. The problem was 100% reproducible as per my previous messages. Then I upgraded to version of 19.3 + kernel 5.3.40 and with the upgrade came newer versions of Chromium/systemd as indicated.
For the last three days I tried desperately to replicate the problem but did not succeed. Only in one instance with 126 open tabs, hibernation failed twice in a row (CanHibernate returned s "yes"), but after a (successful) standby operation, hibernation started to succeed repeatedly. That is a single failure in literally hundreds of attempts, which could very well have been a HW/Bios issue to go in deep standby for S5. Fortunately I was able to automated the testing process using session buddy advanced restore, so all I had to do was watch :-). Also switching between Linux hibernation and Windows 10 hibernation always succeeded. The hibernation speed seemed also to have improved, but I have no hard data to illustrate this. I am happy to report that with: Kernel 5.3.0.28 --> 5.3.0.40 Chromium 79.0.3945 --> 80.0.3987 Systemd 237-3ubuntu10.38 --> 237-3ubuntu10.39 the problem is SOLVED. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1862797 Title: Systemd does not allow hibernation when Chrome/chromium is running To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1862797/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
