Hello all- I first posted this in the BOINC forum a few weeks ago. (https://boinc.berkeley.edu/forum_thread.php?id=12636)
As I've had no response there, I thought it might be better to post here:

This may be a Windows issue, but, as you can imagine, I can't get anywhere in the chaos of Windows user forums, nor did I get a response from Microsoft.
Beginning on a new machine at the beginning of July, once the screensaver is invoked, the only way I can resume my Windows session is to hit control-alt-delete, then hit "cancel" on the next screen (lock, etc/Task Manager screen). Simply hitting a key or moving the mouse will not bring the computer out of the screensaver mode. That does stop the SETI screensaver, but the BOINC standby one takes its place. (Please let me know if I could phrase that better and I will edit this post accordingly.)
This was not occurring on my previous machine, which croaked a week before I started using the new one. I presume the Windows build on the new machine was the same as on the old once it connected and updated itself, but I can't say for sure.
I have seen some threads on various forums describing similar behavior, but most or all seem to relate to some Windows photo (slide show?) screensaver function that I assume does not apply here as I have never used any such feature.
To the best of my knowledge, all my drivers are up to date.
Anyone have any ideas what this could be, or where I might look for an answer?
Thanks in advance.
Eric

Message 1957635 - Posted: 28 Sep 2018, 15:02:34 UTC - in response to Message 1957631.  

I have the same thing with Windows, where when my system goes idle and monitors to sleep, after 10 minutes or more I have to use CTRL+ALT+DEL to wake the system back up. This isn't a BOINC problem (I don't run BOINC on my desktop anymore). The nearest I find is that it's something to do with my mouse drivers software (Logitech, using SetPoint), because when I uninstall that, I don't have this problem anymore (but then a lot less functionality of my mouse as well).

Dank, Jord, for the prompt reply and info! Hadn't thought of that. I wonder if it's my mouse drivers, though, as neither the mouse nor the keyboard will get me back into the session.

Just a thought.

If Jord's idea doesn't work then maybe look at your power settings??

I used to change them from power save to performance.

Spin down the Hard drive to "never" (this assumes you are still using a HDD and not a SSD. If you aren't then it doesn't matter)

System standby to "never"
Hibernate to "never"

These last 2 might not be options for you.

I also never let the screen go blank. But that is a personal preference.


Good luck to you

Thanks, Zalster. I don't think standby and hibernate modes are part of this problem, though, as the computer wakes up fine from them (by hitting any key, or the power button, respectively). I neglected to mention that in my original post; wish I could edit it...
