[solved]Graphic artifacts : Intel Iris Xe

heblah · 2022-08-17 10:39:29

Hi !

I have some tearing on my laptop, to be more precise grey bands jumping trough my screen.
Sorry for the quality but I can't capture the tearing with the Gnome screenshot app so I used my phone and a picture is still better than words :

I don't have tearing in the bios neither during installation or in console mode.

I've tried different solutions :

Other linux distrib (not the point but same tearing artifact)
Reinstall the entire arch system
modify kernel parameters
Install xf86-video-intel
Activate TearFree option in /etc/X11/xorg.conf.d/20-intel.conf
Use different "AccelMethod" options

Here my current GRUB_CMDLINE_LINUX_DEFAULT line in the file /etc/default/grub :

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet i915.enable_guc=2 i915.enable_psr=0"

I've also tried with i915.enable_fbc=0, i915.enable_fbc=1, only psr=0, without the option guc=2, only guc=2... I probably forget some combinations but always followed by a grub-mkconfig -o /boot/grub/grub.cfg command then a reboot

Here my current 20-intel.conf :

Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"
  Option "TearFree" "true"
  Option "AccelMethod" "uxa"
EndSection

I also tried with sna AccelMethod end deleting the entire "AccelMethod" line.

I have less tearing than before but it is still really annoying.

Here the sudo lscpi -v output :

I've just noticed than the kernel driver in use is i915 and not the intel one but I don't know how to change it...

I believe this is a known issue on the modesetting driver: https://gitlab.freedesktop.org/xorg/xse … issues/244

Use a compositor.

heblah · 2022-08-17 14:13:31

yes it is a known issue but none of the found posts solved my case.

I've just installed picom, tried picom & and picom -b :

[ 08/17/2022 15:58:28.668 session_init FATAL ERROR ] Another composite manager is already running

Gnome is supplied with its own compositor, how do I change the default compositor in Gnome ?
Is there a better compositor than picom ? (I'm totally noob with this stuff)

jmandawg · 2022-08-17 16:58:18

Sorry i don't use Gnome, but you can try these kernel params from this thread:

i915.enable_psr=0  i915.enable_fbc=0

Please edit your first post and use "code" tags, not "quote" tags (you'll see, why)

The artifact in the screenshot are NOT tearing and i915 is the proper (and only) kernel module.
Since you're running gnome, you're also probably on a wayland session, so xf86-video-intel, TearFree and /etc/X11/xorg.conf.d/20-intel.conf won't matter at all.

echo $XDG_SESSION_TYPE

This looks very much like a power state issue, but that's a guess - is it exclusive to that gnome mission-control thing (where you change windows)?
Try https://wiki.archlinux.org/title/Intel_ … Intel_CPUs

It's better

Yes I'm on a wayland session. So I can remove all the kernel parameters related to graphic options ?

Before to change the power management options I'm going to uninstall the tlp package... I'll see

I used to use kde but on this laptop (Xiaomi pro 15 2021, oled screen) my screen switched off after a sleep or on minimum brighness. The only way to switch on back was to reboot so I moved on Gnome
And I have the same problem with Swaywm than with Gnome

By the way, simple curiosity :
What is this artifact I'm seeing ? It's not really tearing, neither flickering and it's look like "snow" on old tv...

So I've uninstall the tlp package and tried the tree kernel parameters options together and it's the same thing ! Some times lot of artifacts and sometimes nothing
I also tried each of the tree kernel parameter options and without kernel option : same thing.

When I've installed tlp I did :

 systemctl mask systemd-rfkill.service
 systemctl mask systemd-rfkill.socket
 systemctl enable tlp.service
 systemctl restart tlp.service

So I've tried a :

 systemctl unmask systemd-rfkill.service
 systemctl unmask systemd-rfkill.socket

I don't know what to do...

I hate to say it, but does it happen when you run windows 10?

heblah · 2022-08-18 13:13:24

I don't think but I erased the W10 partition really quickly when I received my laptop...
But I was already downloading the iso to run a test and looking for hardware integrity tests

When I'm in console mode during the arch installation I don't have any artifacts... It's all I can say now
Here the ouput of smartctl -t short /dev/nvme0n1, it doesn't seem to run a test :

This looks like some texture corruption (the framebuffer is fine, the mouse pointer and one window are "above" the artifact and unaffected)
Since it also happens w/ sway, we know it's not a bug in gnome/mutter.
If it's a harware issue, then it's most likely w/ the memory.

Try the lts kernel and "iommu=soft" as kernel parameter.

So i tried a windows 10 installation, it's worst than on linux even after installing intel drivers (windows drivers). I used to use kde, I moved for Gnome because the screen switched off after a sleep or on minimum brightness and I need to reboot but I don't remember of any graphic glitch

Whatever, I'm back on arch and I've less artifacts... Doing nothing (just one more reinstall)

I'll try the kernel parameter and I let you know

My problem can be due to the oled screen of the laptop ?

"Worse" how? Similar artifacts?

That's unlikely because, again: it's not the framebuffer.
If you were talking about the KDE/screen off situation, I'd try that against the PSR parameter.

Yes exactly the same but with an higher frequency

I still have some artifacts with "iommu=soft" parameter

I've just runned a memtest86+ test and I had some artifacts during the test but the ram is ok

[This looks like some texture corruption (the framebuffer is fine, the mouse pointer and one window are "above" the artifact and unaffected)

Th picture quality is bad but I've verified on my phone and the glitch is above the white window, it's less visible because of the color

If you are having the same issue with windows it's def a hardware issue, you need to send in for warranty repair. Or run memtest or gpu test.

Is it always in the same location?
Do you get the same when lowering the resolution?

No it's never the same location and I get the same with lower resolution

I run a memtest, the ram is ok. Is there an integrity hardware GPU test on arch ?

I used to use kde

And did you have this issue w/ KDE?
Do you get the same issue w/ openbox on xorg? Gnome on xorg?

Because I had to reboot my laptop after each time the laptop slept or the scree switched off, I almost didn't use kde on this laptop so I can't really tell you but I've reinstalled kde to test it during one hour without any issue.
I never tried openbox but I had the same issue with xorg Gnome.

I've added the i915.fastboot=1 as kernel parameter and the glitch frequency has decreased a lot

I had this issue since the first linux installation, I modified kernel parameters and I was able to use my laptop during 2 months without any trouble and it comes back doing special (I was on vim)
To be honest I'm totally lost

Did you try another (presumably HDMI) cable?
Ah shit. It's a laptop.
Do these artefacts occur on an external monitor?

parm:           fastboot:Try to skip unnecessary mode sets at boot time (0=disabled, 1=enabled) Default: -1 (use per-chip default) (int)

The only way I can see any impact through this is that you're starting the display server on an uninitialized GPU and in this case see https://wiki.archlinux.org/title/Kernel … _KMS_start

I tested on another monitor and I had artifacts on laptop but not on external monitor. I'm really thinking on a hardware monitor problem, is there way to check screen integrity ? I've run some online tests but it's only for color calibration or dead pixels

I've added the i915 module but it didn't change my issue

I would wager that the internal display cable is broken or has a loose connection.

seth · 2022-08-22 11:20:29

Wouldn't fit

@heblah does the angle of the opened panel matter?

Sorry I didn't understand, what panel are you talking about ?

Probably, I've opened the laptop and cleaned the connection, same thing. On the other side the cable is welded to the screen so if the cable is dead the screen too (I think)

The one w/ the display inside that you can hinge open and close to see what's on the display.
