[Software] A line by height of 1 pixel appears on my screen since 2 days ago

[Hadi_Lovelorn]

Hello , Since 2 days ago until now a graphical line appears on my screen ( desktop , firefox , photos , videos etc ) on the same place . Shall I report it to Kernel team of Debian ? Or it can be solved ?

Here Are Examples :

If You zoom in the 2 photos , You can see the line

System Info :

Debian GNU/Linux 12.5 Bookworm amd64
GNOME 3.43.9
Intel Pentium G3220
GPU : Intel HD Graphics

Did you just upgrade to 12.5 2 days ago, or change anything else in the past 2 days?

What you describe is a possible result of a display failure.

It's possible a driver switch could make a difference. Please paste output from:

Code: Select all

inxi -GSaz --vs

Note: I could see neither image, as your image host requires JS be enabled. Were they attached here I could.

I upgraded my Kernel , 3 or 4 days ago ........ But I didn't change any thing
The image host is safe , You can enable Your JS on it
Your code didn't work , bash : command not found
Should I run it as sudo ? is it safe ?

You have to install it first, as root or with sudo

This suggests the xserver-xorg-video-intel .deb is not installed. Usually if it is, then where "modesetting" appears in inxi output you would instead see "intel" and "modesetting" would instead appear in the "unloaded" group. The modesetting DIX is actually the preferred display driver, but you may try this switch to see if it makes any difference to use the intel DDX. I suspect it will not.

To make the switch it should be sufficient to simply install the .deb and restart X or reboot. If that does not happen you may need a config file to specify its use in /etc/X11/xorg.conf.d./, or to alter an existing one to not specify modesetting.

Does the line appear during boot, viewable in an OEM logo or the bios screen or even grub, to determine if it's a hardware defect?

It is installed Sir , 2.99.917+git2021 version is installed , But if I should configure a file tell me what should I write ( is it safe ? )

No Sir , It doesn't appear until the Debian starts up , I guess You are right ; It's not a Kernel problem ...... But one day after Kernel upgrade ( and after I shut down system and boot it after day ) it appeared , so I suspected if it's Kernel problem . Thanks ....

If /etc/X11/xorg.conf does not exist, and no files currently exist in /etc/X11/xorg.conf.d/, or if any that exist contain no uncommented line that contains 'Section "Device"', then you may create a file named 15-intel.conf with the following content:

Code: Select all

Section "Device"
  Identifier "DDX"
	Driver "intel"
#	Driver "modesetting"
EndSection

The modesetting line is an unnecessary comment (indicated by #). It's presence makes it simple to switch between using modesetting driver and intel driver simply by moving the "#" to the line not to be applied, then restarting X. Of course, removing the file will also restore former behavior.

Hello Sir

I created the file in X11 directory with the name You said and copy-pasted the config script ..... I logged out and logged in to X.org but the line still exist

That suggests it's likely not a software issue. Nevertheless, it may yet be possible to remove. Please find file Xorg.0.log. It should be in /var/log/ or in ~/.local/share/xorg/. Copy it to Xorg0log.text, then either attach it to a reply here for our analysis, or use the pastebinit command to upload it to Debian's pastebin and give us here the link to it. The file, if created by X11 rather than Wayland, is too large for pasting into a reply.

My G3220 using Bookworm does not produce any such line on any of my 3 displays:

I don't know where is Debian Pastebin , But I pasted to another site :

https://www.toptal.com/developers/paste-gd/7I6j6a6J

[mrmazda]

Possibly you can eliminate the problem by using a digital monitor connection (HDMI, DisplayPort, DVI, USB-C) instead of analog (VGA). Digital display connections generally omit two digital⇔analog conversion steps in getting an original image onto a computer display.

Your choice of pastebin doesn't allow me full access as would an attachment to the thread, or using the pastebinit command, or a pastebin site offering to show paste in raw mode instead of hiding most of the paste under unnecessary whitespace. Debian's pastebin site can be found among the following:

• http://paste.debian.net/
• http://paste.opendev.org/
• http://paste.opensuse.org/
• http://paste.centos.org/
• http://paste.fedoraproject.org

I don't think it's a Monitor problem ; since it works well before GNOME starts up ....

Here's the config info :

Video mode switches at various times between POST and reaching your login screen.

Do you plan to try a HDMI cable? If your PC's display has no HDMI port, use a TV to test, a good idea in any event anyway.

If it was my monitor problem , Then the line wouldn't be visible in the photos ..... Nice advise , but I haven't HDMI cable .......

[mrmazda]

I haven't HDMI cable .......

If you wish to determine what your problem is, find a way to get one long enough to test. I've seen them for sale for as little as $2US.
