Can I get you to try to reproduce this using cinnamon-screensaver --debug (you can use cinnamon-screensaver-command -e or killall cinnamon-screensaver

Also, is there any generated report for this? (check "System Reports" in the menu)

Thanks

I'll try with debug, but it's only sometimes... No system reports for this (I had a few for other events). I had this before (18.1 or 18.2), so I still have a key combination for a screensaver "restart" to solve this cinnamon-screensaver-command -e >/dev/null 2>&1 && nohup cinnamon-screensaver >/dev/null 2>&1 &

Ok, I have a log for you... Here is what I did: Connect an HDMI-cable to get sound with an spdif-converter. This is interpreted as second monitor wich is absent, I use it only to send the sound to a receiver. Also I switched to a second user, watched some movies. Then I logged out from user 2 and logged back into my user account, then the screensaver was still active.

Okay, something like this never occurred to me.. I've ordered one of these extractors.. I'm curious what's happening, and how our libraries interpret that sort of device. Should have in a couple days. If I can reproduce this, a fix will be pretty simple.

[mtwebster]

Can you try this file out:

https://www.dropbox.com/s/il1y8cv20pm5jzl/stage.py?dl=0

Download it to some folder, then open a terminal in that folder and run:

sudo cp stage.py /usr/share/cinnamon-screensaver

Then kill and restart the screensaver.

Thanks

[Mintulix]

Thanks a lot Michael, also for ordering an HDMI-Converter just for debugging :-). I patched stage.py, will test it later this evening and the next days and report.

[Mintulix]

Hmm, just had the bug again with the patched stage.py. HDMI was not plugged in this time, but I switched users again. I think I have to test a few more days with the --debug switch on...

[Mintulix]

Hi, I have a new debug log. Just changed users like before, no HDMI cable involved (sorry for misleading).

For what it is worth: I too, but on Mint 20.2, see an error message (in my log) similar to one reported here. That error message that I see is: 'org.cinnamon.ScreenSaver: Error writing to child - Error writing to file descriptor: Broken pipe'.

On weirdness caused by HDMI cables: please cf. this open issue filed against Cinnamon.
