Softwere update installed an update earlier today, and when it rebooted I noticed it took double to triple the time to boot once it got to the Zorin splash, NBD it's not like that's very long. However, I'm now finding that the computer is running very "slowly" and behaving unexpectedly. Namely gnome-shell process is spiking use on all processor cores together and to an unreasonably high level.
This image is upon a fresh reboot, and those 75% usage spikes are from dragging the system monitor window around with the mouse a little. As you can see from it as well, my system specs have absolutely no business being dragged down by that.
Any-clue what's happening? I want to understand.
Secondly, what can I do to fix this? I assume there's a way to roll back an update, and I'll go looking for it in a bit, but I'll be honest I've not been very successful in finding good technical support online for zorin so far. Is it easier to get support if you have pro?
If the software update included kernel update from 6.5* to 6.8* then you could try and boot an older 6.5 kernel generic from grub menu item "Advanced options for Zorin". See if that helps. There are ways to set that as default if that is your solution.
Did You take a Look at the Proccesses Tab to look what Proccesses are could causing this Behavior? Maybe You could post a Screenshot from this, too if possible?
Yes, as i stated the process responsable for these spikes is gnome-shell. There was nothing else running besides things that start with a vanilla installation of zorin os on boot up, and system monitor, which you can see was only just started.
I was in a rush to leave when the update dialogue popped up, so i didn't read it properly this time and just hit ok and walked away, so I'm not actually sure if a kernel update was involved. Regardless, thanks for the tip, and I will try checking/rolling back the kernel version when i get back home today.
Zabadabadoo, was correct. As I said I didn't properly read the update this time (normally I do but was in a hurry) but kernel 6.8.0-40-generic was the one I was running with the issue, grub boot menu (AKA advanced options for Zorin) after a few tries with different keys, but it was with rapid tapping on right shift key that got me in.
Rolled back to 6.5.0-45-generic and issues were resolved.
I then followed Aravision's post to make my current kernel version saved and default boot. While I was there I noticed and changed the GRUB_TIMEOUT from 0 to 2, so hopefully I won't have to try so many times to get into it next time I have to do so.
Finally, I would still love to know why 6.8 was doing that, if anybody knows what resources I could go to to learn that would be awesome.
