Help with display problem (momentary short horizontal lines)

Support and Help
1

Hello, all,

I’m continuing to have problems with my Ubuntu 24.04.4 system running on two displays. I wrote about it at Best place to ask question about display problems, possibly related to Nvidia update? , but wasn’t able to get any help at the two resources offered.

I still think my problem with short, horizontal lines appearing when the screen refreshes or changes are related to an Nvidia update about 6-8 months ago, but now, I’m so frustrated, I just want to wipe out my entire video driver system and start over from scratch. However, I’m not sure if this is a good way of fixing the problem, or if it’s even possible, as wiping out the video system means I won’t have any way of interacting with my system.

My problem again are short (1/4inch), horizontal lines that appear when the screen is redrawn. For instance, now, as I’m typing, the last letter I type can be distorted with the lines, which disappear as soon as the next letter is typed. This is especially maddening to me, as I mostly use Emacs, and I can’t tell where the cursor is, as it’s the only thing that updates on the screen, and can appear in two different locations, with the short horizontal lines. It’s almost as if the memory area where the display image is stored is out of sync with the routine redrawing the screen.

Thanks for any suggestions or advice.

Kevin – details
is this a desktop or laptop?
resolution of displays, nvidia driver, …
have you run a memory check on your system
are all cables plugged all the way in

@pavlos, thanks for replying.

Short answers:

Desktop

Resolution: see below

Haven’t run memory check. How to do this? How to test video memory?

All cables are plugged in and secure.

Here’s the output of a script I ran, that gives this information (was posted in the article I linked to):

In short,

2 monitors 1080 (DVI, HDMI), Nvidia driver 580.95, GT 1030

I assume display settings have refresh rate 60 Hz (usually thin lines indicate bad sync)

inxi -G will give us a short version of the graphics

Is there a better nvidia driver for this GPU or should you use a previous driver?

Is wayland an issue? can you login in X11?

As for memory check, your BIOS should have an option to run memcheck

Some ideas.

you could run with one display, do you see thin lines? then plug in second display, thin lines?

My inxi -G is:

As should Ubuntu’s GRUB bootloader, because the ubuntu-desktop-minimal recommends memtest86+, which can be selected from the GRUB menu on boot. Holding the Shift key or pressing Esc after the BIOS/UEFI splash screen should bring up that menu. But that’s purely for system RAM. I don’t know of any tool that does the same for GPU RAM.

@kzembower, you can make sure that memtest86+ is installed by running sudo apt install memtest86+ and, if that does not automatically update GRUB’s menu, sudo update-grub.

Other answers:

Yes, refresh rate on both monitors is 60.00Hz.

Don’t know about a better nvidia driver for this GPU. I don’t know how to find this information.

Can no longer log into Wayland on initial power-on (I could have sworn that I used to be able to do this.) I don’t have another computer with X11 to try to ssh into (this is what you were asking me to test, correct?)

I’ll try the memory check and single display when I have some time that I’m not under a deadline.

Thanks for all the suggestions.

Is the first display rotated, why does it report 1080x1920 instead of 1920x1080 ?

8

There have been many discussions related to the NVIDIA driver support, Users freezing versions to prevent “non-sanity” associated with some newer drivers, other Users rolling back to earlier drivers because of issues.

I suggest you do a search for nvidia driver on the old UbuntuMATE site at

One particularly useful discussion can be found here, especially since you refer to Ubuntu 24.04.

Yes, display 1, the HP Compaq LA2306x, is rotated to portrait orientation.

The discussion about holding to the nvidia-550 drivers seems useful. I’m at 580:

$ inxi -Gxxx
Graphics:
  Device-1: Intel Xeon E3-1200 v3/4th Gen Core Processor Integrated
    Graphics vendor: ASRock driver: i915 v: kernel arch: Gen-7.5 ports:

  Device-2: NVIDIA GP108 [GeForce GT 1030] vendor: Gigabyte
    driver: nvidia v: 580.126.09 arch: Pascal pcie: speed: 8 GT/s lanes: 4

However, the page linked to in that discussion was to the amd64 build of the drivers. I have an x86_64 processor:

$ lscpu
Architecture:             x86_64
  CPU op-mode(s):         32-bit, 64-bit
  Address sizes:          39 bits physical, 48 bits virtual
  Byte Order:             Little Endian
CPU(s):                   4
  On-line CPU(s) list:    0-3
Vendor ID:                GenuineIntel
  Model name:             Intel(R) Core(TM) i5-4670K CPU @ 3.40GHz
    CPU family:           6
    Model:                60
...

Is there any published source of directions of how to download the nvidia-550 drivers built for x86_64 architecture, and how to disable to -580 version and install the -550 one?

Thanks, again, for your help.

-Kevin

11

This is referring to your CPU, both indicate a 64 bit architecture.

12

Have you looked at this site?

  • SNAPSHOT__NVIDIA_Drivers_550

Or maybe, check here:


An alternate would be this:


If you want to stay on top of what is happening with drivers, you may want to follow this:


The following points to some discussions that my also give you better understanding/insights into what you are dealing with, and how to resolve. :slight_smile:

13

Yes, but AMD is a very different architecture than Intel.

-Kevin

14

I’m in the middle of following this page right now:

https://fosslinux.community/forum/linux-gaming/how-to-reinstall-nvidia-gpu-drivers-on-ubuntu-desktop/

but, I’m confused, because even though I specified “sudo apt-get install nvidia-driver-550" it’s still installing packages from -580. After it finishes, I’ll reboot and see if anything’s changed.

Thanks, again.

-Kevin

15

usually, you purge all nvidia packages, reboot, your pc will load the default nouveau driver, then you install the nvidia driver of your choice.

sudo apt purge nvidia*

reboot

sudo apt install nvidia-driver-550

Referencing that article you mentionned, if you added the PPA, then did a package refresh, you should be able to see/list the 550-related files available for download. If not, then you need to tell the system to override the central repository. But I am not an expert at that. Others out there could give you specifics on making that work for you.


If you follow Pavlos’s (@pavlos ) advice, you can’t go wrong!

Nope, to answer myself, following the directions at https://fosslinux.community/forum/linux-gaming/how-to-reinstall-nvidia-gpu-drivers-on-ubuntu-desktop/ didn’t help. Still same symptoms as before.

However, I didn’t install the PPA. I didn’t want to if I didn’t have to. Now, I’ll repeat the steps from that page, but with the PPA, and see if that makes a difference.

-Kevin

18

@pavlos, thanks for replying, but nope, it didn’t work. Still installed versions from -580 (but this is still without the PPA). I’ll try it again, with the PPA this time.

Before I do that, my display seems to be just fine with the "default nouveau driver” (Don’t know what this is). What would be the reasons to install the nvidia drivers at all?

-Kevin

19

usually nouveau is slower but if it works for you, no reason to install nvidia.

it seems nvidia-driver-550 points to 580

The Nouveau driver is an open-source, community-developed Linux graphics driver for NVIDIA GPUs, designed to provide free software alternatives to proprietary drivers. It offers decent 2D/3D performance for older cards.

20

Still didn’t work correctly with PPA installed. I said, “sudo ap-get install nvidia-driver-550” after correctly installing the PPA, but still got packages from -580, and after reboot, still had the same symptoms.

I think I’m just going to purge the nvidia* packages, and use the default nouveau driver, which seems to work fine for me. Still interested in reasons why I should use the nvidia drivers.

Thanks, all, for your help and advice.
