Benchmark Your GPU In Lubuntu

Today we have a simple enough article, meant for fun and information, as we talk about how to benchmark your GPU in Lubuntu. This won’t be a very long and complicated article. Even a new user should be able to follow along.

We all like to know where we stand in life. This is true even with computers. At the very least, we want to know that our computer can accomplish the tasks we need it to accomplish. One of the ways you can do this is to benchmark your computer.

I’ve previously written a couple of articles that involve benchmarking.

Benchmark Your Linux Box With Geekbench 5
Check Disk Speed In The Terminal
Graphically Examine Hardware Info With HardInfo

So, this isn’t a foreign concept to my regular readers (whom I appreciate a great deal).

A benchmark pushes your hardware to the limits and then gives you a score telling you how well it did. Usually, the next step will be using your search engine to find out how well you did against other computers. (Those with older and slow computers may not do this, but I did with a recently purchased refurbished device, and it did not do well – but it still perfectly satisfies my needs.)

Your GPU obviously controls your graphics. I do not need massive graphic capabilities. I’m content with onboard graphics and my benchmark score shows this. At most, I’m going to stream a video, watch a movie, or play a game that doesn’t require high-end graphics.

You should know about Lubuntu already. The directions for this article are for Lubuntu, but will likely work with most other distros. For this exercise, we’ll be using glmark2.

Installing glmark2:

The first step to using glmark2 is opening your terminal. To open your terminal, CTRL + ALT + T. Then, with your terminal now open, enter the following command to ensure your system’s application database is up to date:

Let that run its course and don’t worry about upgrading at this point. You can always do that later, though I’d suggest doing so as soon as realistically possible because updates tend to contain security updates and those are important.

The next goal is to install glmark2 and you do that with this command:

If you’re not using Lubuntu and you’re using a distro with Wayland, then you want a different command. That command might be something like this:

With glmark2 now installed, it would be worth your time to check the man page. This article will only cover the very basic command, literally running the command without any flags, but there are many options available for you. To check the man page, use this command:

As you can see, there are quite a few options available. I will not be doing a deep dive into those options. You can easily figure most of them out on your own. Heck, you can probably figure them all out with a little trial and error.

Now that you have the GPU benchmarking tool, glmark2, installed in Lubuntu you can run the command in the terminal…

Benchmark Your GPU In Lubuntu:

If you’ve installed glmark2 and checked the man page, you’ll see that we’ve chosen the right tool for the job. The man page describes glmark2 as:

glmark2 – OpenGL (ES) 2.0 benchmark suite

So, assuming you’ve kept your terminal open (if not, open it again) then you need to simply use the command’s name to run a benchmark on your system. It’s that simple to benchmark your GPU in Lubuntu. Just try this command:

In theory, you should not do anything with your computer while this runs. I, of course, did not listen to that advice and I’m perfectly okay with that. As I mentioned above, my graphical needs are not high. The Intel graphics are just fine for me.

That’s going to take a while, especially on an older computer like mine – and one with just an onboard GPU. This should open a new window and display a bunch of graphics in that window. If you didn’t do this in full-screen mode, that is without any flags to set that value, you’ll also be able to see quite a lot of information scrolling by in your terminal. Someone smarter than I am can tell you what that information means.

Wait for the benchmark to end, that’s when the new window closes, and collect your score from the terminal. Mine was not very high.

Then, use your favorite search engine to see how well you did compared to other users. If you want to compare your score against other computers, you can try this OpenBenchmarking link. I’m sure there are other sites where you can compare your score with others. That’s just the one I happened to find in a very brief search.


So, I don’t know if you actually want to benchmark your GPU in Lubuntu. If you do, now you know how. It’s not terribly complicated and it is something you can do in just a few short minutes.

You’re not supposed to use your computer at the same time, but I had dozens of windows open and was streaming a video during my benchmark. In my case, it doesn’t matter to me. I have no need for more powerful graphics and I’m content with the performance I get from this device. It’s perfectly capable of meeting my needs.
