Help with Cinnamon theme toggle script

[minthelp777]

I have a script that I use to toggle between light and dark Cinnamon themes, but it occasionally crashes Cinnamon (into "fallback" mode), which is frustrating because it resizes some windows when it does. I've used this script for about 2 years or so and it has always occasionally crashed Cinnamon. Not sure what causes the crash, and I've debugged it the best I know how. It doesn't seem to be memory related and I can't isolate it to one command.

The script also restarts Audacious (music player), which I usually have running, and applies a light/dark theme to that, as well. This is the only way I've found to change the Audacious skin with a script.

Am I using any commands that I shouldn't be or am I doing something incorrectly?

It works most of the time, but the crash is unexpected and I can't figure it out.

Thanks.

After it crashes, check ~/.xsession-errors. It often has details on what caused the crash.

Yeah, thanks, I've tried that. It wasn't helpful, unfortunately.

In fact, I've tried to watch the memory usage as it runs with code like this wrapped around every command, but it didn't tell me much, either:

Code: Select all

freeram=$(free -m | grep Swap | awk '{print ($3/$2)*100}')
echo "=== Free RAM is $freeram%" >> ~/.xsession-errors
echo $(date +%Y-%m-%d_%H:%M:%S) >> ~/.xsession-errors

Anyone use a different way of switching themes (with one click) that doesn't crash Cinnamon?
