Well the good news is that Suspend appears to have worked and my Ibercivis Tasks appear to have resumed from where they left off. Thanks for the idea Tim! I've just spent some time looking into this tuxonice thing, but with no real success so far. I found this: https://launchpad.net/~tuxonice/+archive/ubuntu/ppa so I applied the PPA, but when I ran apt update, I got: Ign:1 http://ppa.launchpad.net/tuxonice/ppa/ubuntu eoan InRelease Hit:2 http://gb.archive.ubuntu.com/ubuntu eoan InRelease Hit:3 http://gb.archive.ubuntu.com/ubuntu eoan-updates InRelease Err:4 http://ppa.launchpad.net/tuxonice/ppa/ubuntu eoan Release 404 Not Found [IP: 91.189.95.83 80] Hit:5 http://gb.archive.ubuntu.com/ubuntu eoan-backports InRelease Hit:6 https://packages.microsoft.com/repos/ms-teams stable InRelease Hit:7 http://security.ubuntu.com/ubuntu eoan-security InRelease Reading package lists... Done E: The repository 'http://ppa.launchpad.net/tuxonice/ppa/ubuntu eoan Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. TBH, I'm not going to spend any more time on this. Suspend appears to work OK for me and apart from a flashing LED and extra power consumption overnight, there seem to be no disadvantages to it. However, if anyone was considering trying to get hibernate to work, here's your starting point perhaps. Note that on the page I linked to above it states that: 'In general, you do NOT need to change any configuration file and you do NOT need to install the hibernate package.' I presume that the tuxonice-userui, which is in the 19.10 Repository (even though the tuxonice kernel patch isn't), would make configuration easier. -- Terry Coles -- Next meeting: Online, Jitsi, Tuesday, 2020-05-05 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk

You made me do it.. I ran up my ancient Dell Inspiron 6000 (32 bit) running xubuntu 18.04, and it has a suspend feature, but no obvious hibernate.

I haven't encrypted my laptop because it rarely leaves the house (my wife uses it mostly). I probably should because I might leave it in the pub/club after a LUG Meeting, but that's unlikely to happen any time soon! I have never felt it necessary to encrypt my desktop. In any case, there is very little on either machine that is of any value to anyone else. I use a Password Manager for my many passwords. So my un-encrypted laptop still doesn't support hibernation. -- Terry Coles -- Next meeting: Online, Jitsi, Tuesday, 2020-05-05 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
Re: [Dorset] Hibernate in (K)Ubuntu
It's probably worth mentioning that hibernate is (usually) incompatible with encrypted swap, which you would normally have if you are using any kind of disk encryption. When (K)Ubuntu first started offering encrypted home directories as a standard feature, I did not immediately make the connection that enabling that feature was the reason why I'd lost the ability to hibernate my laptop. If you think about it, it makes perfect sense, but I didn't think about it! I did find this, however: https://help.ubuntu.com/community/EnableHibernateWithEncryptedSwap -- Next meeting: Online, Jitsi, Tuesday, 2020-05-05 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk

[Dorset] Hibernate in (K)Ubuntu
After yesterday's discussion in the 'New BOINC project that does computing for COVID-19' thread and last night's discussion online, I decided to pursue Ralph's suggestion to use systemd to hibernate the machine. I've started a new thread because this really has nothing to do with BOINC! Anyway, I started off by searching for systemd hibernate and found this: http://manpages.ubuntu.com/manpages/bionic/man8/systemd-suspend.service.8.html Amongst other things this says: 'Note that systemd-suspend.service, systemd-hibernate.service, and systemd- hybrid-sleep.service systemd-suspend-then-hibernate.service should never be executed directly. Instead, trigger system sleep states with a command such as "systemctl suspend" or similar.' So I searched for 'systemctl hibernate' and found quite a few complaints about this not working in Kubuntu and Ubuntu and it would seem to me, reading a number of pages, that these distros are not set up for hibernation by default. I haven't found an equivalent page for Kubuntu 18.10 (which I'm running), but this page for 18.04 sets out what needs to be done: https://askubuntu.com/questions/1031633/enable-hibernate-in-ubuntu-18-04-lts I'm still debating whether or not I should try this or simply use Suspend (to RAM). BTW. My laptop doesn't support Hibernate either, but I can recall doing on an old one that I had some years ago. (I've only run Kubuntu on my personal machine since around 2002, so it used to do it once.) -- Terry Coles -- Next meeting: Online, Jitsi, Tuesday, 2020-05-05 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
