A bit over a year ago now I needed to set up my daughter with a computer for distance learning, I used my mother's old iMac from around 2011 I think. 8gib memory, i5-2400s 2.5ghz x4, running Ubuntu 20.04 without a hitch, love it, works great
fast forward and my youngest is in kindergarten now, wants to be like big sister with a computer, got an iMac from a friend that's very similar, I think it's late 2009 or 2010. Also 8gib memory but cpu is a dual core Intel e7600, so yeah a bit less powerful but should be good.
Problem is there are long pauses in operations, especially opening Firefox, to the point it isn't useable - what's the best way to troubleshoot? 20.04 Ubuntu installs fine and depending on what we do it works good, just don't go online I guess... Just installed 21.10 to see if that could help, but I'm thinking may just be best to use a lighter weight distro... I would just prefer them to have a similar experience using a computer so they can help each other out - appreciate any advice here!

What is graphics adapter or graphics card because weak graphics will load the processor down.

To many browser extensions can slow a browser down.

Copy and paste this command in the terminal
Code:
inxi -Fxz
Copy and paste the output from that in a post.

Someone with more Linux knowledge than I will be by.

Welcome to the forum.


Thanks!
Hate to do this but I'm attaching a pic of the output since I can't get any browser to work. I looked to see if any proprietary graphics drivers were installed and at least according to the softy center no, so I'm assuming I'm using an open source driver that isn't playing nice?

Logout of Ubuntu and then try selecting "Ubuntu on Xorg" instead of using Wayland. See the the screenshot.

How does Firefox react when you are using an Xorg session?

well I see nothing wrong with the Fxz report
the graphics are using the kernel drivers, things may improve if you install proprietary drivers.

Yes you can also try that but I know that the proprietary Nvidia drivers aren't working fully correctly yet with a Wayland session. So I would first log into an Xorg session to see how Firefox reacts than, if it still reacts the same as before, then go to additional drivers, select the Nvidia driver and hit apply so that it downloads and installs it. Then reboot and login to an Xorg session to see how Firefox reacts then, you can then also see how Firefox reacts with the Wayland session for a comparison?

Xorg still is freezing, know where do I get the proper nvida drivers?

In the search menu, search for the word "driver", then select "Additional drivers", from there select the Nvidia driver and then select "Apply. It will then download and install the drivers, after which you will have to reboot.

if you search "GeForce 9400 linux drivers" you will find it, BUT there are also problems with using Legacy drivers with later Linux kernels [they do not play nicely togeather]

Copy and paste this command in the terminal to see if the Nvidia driver is installed.
Code:
lsmod | grep nvidia

If no output is displayed than copy and paste this command in the terminal.
Code:
lsmod | grep nouveau

Whichever displays an output is the driver that is installed and running.
