1. Download the 7.16.3 versions of the boinc, boinc-client, boinc-manager, and libboinc7 packages from the 19.10 sources. I chose the amd64 architecture since I am on an x86_64 system.


boinc: https://packages.ubuntu.com/eoan/all/boinc/download
boinc-client: https://packages.ubuntu.com/eoan/boinc-client
boinc-manager: https://packages.ubuntu.com/eoan/boinc-manager
libboinc7: https://packages.ubuntu.com/eoan/libboinc7




2. Manually install the packages with dpkg. For me, this command looked like this:


sudo dpkg -i boinc_7.16.3+dfsg-1_all.deb boinc-client_7.16.3+dfsg-1_amd64.deb boinc-manager_7.16.3+dfsg-1_amd64.deb libboinc7_7.16.3+dfsg-1_amd64.deb 



3. After the packages have been downgraded, you need to hold them so they do not automatically update. This can be done with:


sudo apt-mark hold boinc boinc-client boinc-manager libboinc7

I don't know if this will work on Ubuntu derivatives such as Kubuntu or Lubuntu. If this problem is fixed in a future version of BOINC, you can unhold the packages with

sudo apt-mark unhold boinc boinc-client boinc-manager libboinc7

What values do you have set for the various When to suspend options in Computing preferences ?

Do you get anything in /var/log/pm-suspend.log?

No such file or directory. I suppose I should have mentioned my version. I'm currently running on Ubuntu 16.10, and I've heard that some configs are a little different in systemd.

Need to keep an eye on pm-utils bug

You don't say exactly how you are "sleeping" - can you be specific?

Have you tried sleeping / hibernating via the command line sudo pm-hibernate ?

Do you get anything in /var/log/pm-suspend.log?

The BOINC client must run to allow boincmd to do the commands to it. So make sure you run BOINC (boinc-client).

But why not use the Compute only between N and N preferences you can set through the web site global computing preferences? That way you can tell BOINC to end calculations gracefully minutes before your sleep kicks in.

Or are you saying that you put your computer to sleep before you leave the system? Perhaps that you then take the couple of seconds to set BOINC to suspend as well, or automate the sleep function and use the preferences of run only between... You can even add the Suspend when no mouse/keyboard input in last N minutes preference and and have the sleep function check for system idleness before going to sleep.

Is there a way to keep this from happening, or to somehow signal BOINC to suspend GPU work just before Ubuntu enters sleep mode?

See askubuntu.com for details.

I would add a 20_boinc script with hibernate and suspend entries

boinccmd --set_gpu_mode never 

and for thaw, resume

boinccmd --set_gpu_mode auto 

You might need to add a small delay for boinc the actually shut down the GPU tasks, a few seconds at most.
hth

Woohoo!! Sometimes silence is good:) Give those poor servers some rest and reboots and stuff:)

So, pound sand.

Problem fixed by uninstalling BOINC.

BOINC may have been writing client_state.xml or account*.xml files when the computer locked up. That may have corrupted the files. Or, without knowing what files you moved, you may have caused the problems yourself. BOINC doesn't like when its files disappear.

The next time you need to control the client without starting it, edit client_state.xml file. Elements that correspond to the Activity menu in Manager are:

<user_run_request>
<user_gpu_request>
<user_network_request>

And the values to use:

1 = always
2 = based on preferences
3 = suspend
