Help with laggy UI

Hi everyone,

I am new to OpenSuse and have a question about the typical behavior you see as you use your system. I am on a fresh install of tumbleweed and running plasma 5. I have noticed that as I use the machine, it can be a bit laggy. Like the UI thread is hung. Most of the time it’s for a short amount of time. Just enough to be noticable. I have been running OSX for the last 5 years and decided to make the switch to linux. So basically, i’m wondering if my hardware isn’t up to snuff or if this is just how things generally behave with this distro. I really haven’t used any other distro long enough to say whether i’ve seen it elsewhere. I landed on opensuse and really like it. I’ll say that i didn’t really see this kind of behavior with OSX and i can’t imagine this is really a lack of oopmh in the hardware. Any thoughts?

My hardware setup:
iMac with a core 2 duo @ 3Ghz (2009 version)
12GiB of ram
480GiB SSD

Cheers!

Was your iMac equipped with the nVidia GPU or the Radeon one?

The Radeon. Do you think it’s a driver issue?

Your HW seems more than adequate. Here with:

Core2 Duo @ 1.8 GHz
2GiB RAM
SSD
Intel integrated graphics (2007)

everything plays as charm… when everything is in its place!
Looks like a video acceleration issue, or some multimedia plugin or app eating away more than its fair share…

Good to know. Thanks for replying. I think it may have something to do with LibreOffice being open. I’m going to see if i can narrow it down.
