Cinnamon Performance nosedives after idle of 2 hours

Post by linux_guy0331 »

I have a laptop with a 5th generation intel i5, 512 gb SSD, and 16gb of RAM. Everything relating to cinnamon works flawlessly, unless I let the laptop idle (without going into suspend mode, as suspend prevents this issue). If there is an idle period of 1 or 2 hours where the screen is shut off with no activity, when I log bag into my session the speed of Cinnamon is reduced by about 75%. By viewing top, cinnamon's CPU usage hovers at 100%, and memory is around 10%. Normal CPU usage when cinnamon is performing properly is around 5 - 20% depending on the input given to cinnamon, and normal memory usage is 1 - 2%. Restarting cinnamon fixes this, but I'd rather not have to manually restart anytime I get back on my computer. I've tried disabling all window effects and resetting cinnamon to the default settings, but it does not help.

What can I do to help solve this issue? some people have said it could be a graphics driver issue. Model is a HP Elitebook 840 G2, on linux mint 19.3.

First make a list of processes when your laptop runs normally.
Open the terminal, maximise screen size and run:

Code: Select all

top > list
You may have to break out of the command using ctrL+c to stop it running.
Make sure you have htop installed, if not issue sudo apt-get install htop

Now after 2 hours when your laptop is sluggish start htop from the terminal.
It should show which processes are resource hungry, you can post a screenshot if
you want, or compare it to the textfile "list" which you created earlier.

Did you, by any chance, install any applets or desklets in your Cinnamon? They're the usual suspects for memory leaks and instability.
