Display of DELL Optiplex 9010 all-in-one shaking on Ubuntu 20.04 LTS

in flag

I am using a DELL Optiplex 9010 all-in-one machine for a long time with Ubuntu without having any issues. After having some updates, I did not restart the machine for 3-4 days. When I finally restart the machine the display starts shaking. I thought it may be an update issue. So I did update again (a few days later) with sudo apt-get update and sudo apt-get upgrade. Restarted the machine. But the problem is still there. Here I am attaching some pictures of the display taken by mobile phone.

  1. When booting the Dell logo is fine. So I think the issue is not with the monitor.

  1. When the ubuntu logo appears it starts shaking:

  1. Finally os loaded and continue shaking, please see the date and time at the top:

How can I fix it without reinstalling the OS?

Any help would be appreciated. Thank you.

UPDATE: I have tested by connecting an external monitor. The external monitor display was fine. So Optiplex display went bad.

No need to reinstall. You can and should test it in a live session. If the problem persists then it's hardware. I strongly suspect it is considering that it has only and Intel integrated graphics that usually just works.

@ChanganAuto Thanks for your comment. Yes, it does not have any external GPU. Any suggestion on how could I try to fix it?

If it's an hardware problem I'm afraid there's no fix other than replacing the CPU.

Change the default in the linux grub file as follows for a Dell 9010 AIO:

grub_cmdline_linux_default= "quiet splash nomodeset acpi_osi=Linux acpi_backlight=Dell"

works for me on Zorin. Still can't modify the brightness though.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
