Troubleshooting Ubuntu 18.04 Screen Issues: Pink Discoloration and GPU Usage

It's just that pink is by far the most common color.In summary, The conversation is about a pink color appearing on the monitor while using Ubuntu, but not on Windows. It is suspected to be a video driver issue and the user has an AMD Radeon RX 570 with the commercial driver. The problem comes and goes, and may be related to thermal issues or dirty connections. It is also mentioned that the user runs OpenFOAM, but it does not use the GPU.

Hi PF!

Can you see the upper-left pink on my monitor? It comes and goes, though I don't think I've ever seen it on Windows, only Ubuntu (to be fair Ubuntu runs about 99% of the time). Do you know what it's from, or anything about it?

Thanks for your time!

Josh

So is this Ubuntu running under WSL on Windows 10 or Ubuntu running as a dual boot with the option to switch to Windows on the next boot?

The entire SSD runs Ubuntu. Then a separate HD runs Windows. At boot-up I select which drive to boot from.

Video driver problem is my immediate thought, although initializing the video card at boot time is a possibility.

You state the problem "comes and goes."
Are you saying that it change during a session, or that sometimes it boots to that condition and stays present until a reboot? What about immediately successive reboots?

If changing during a session, it may be a thermal problem with the video card, or a particular application being strange, or maybe just dirty edge contacts on the video card.

And there is always the possibility it's a problem with the display.

Good Luck! You have now entered the brave new world of troubleshooting.

Cheers,
Tom

Yes, it's just an Ubuntu problem (to my knowledge). Of course, I do most cpu-intensive work from Ubuntu and am running it almost exclusively.

I've never seen it boot to that condition: the problem "comes and goes" (currently gone and I have not shut down the system since the picture in post 1).

Thanks for the reply Tom. I'll check my cable connections and see what happens. Was thinking it's likely not a display issue since it comes-and-goes and since I have yet to see any issues from the Windows HD. I monitor the temps from the cpu and gpu: not sure this is it but next time I see the problem I'll check it right away.

Do you mean the horizontal stripes above "Activity"?

Mine too. Is this Intel integrated graphics, or a card? If it is an NVIDIA card are you using the commercial driver or the GPL one?

It is a Radeon RX 570. I'm using AMDs commercial driver.

Good. Another thought - are you the guy that's using OpenFOAM? Is this (or anything else) using the GPU?

My previous monitor had vertical colored stripes coming up from the bottom edge mostly. They faded out as it warmed out.

Does screenshot show it?

Yea, I use OpenFOAM. OpenFOAM does not use the GPU.

Yea, screenshot shows it. Problem is not exclusively pink, and not exclusively in the upper-left corner.
