[Unsolved] Screen tearing, slow text input, screen flashing in games

Hello guys! This is my second post, after the initial one where I asked for help to install Arch all the way, which I did, congrats to you. Now, my next issue is that, after I entered the desktop environment, I noticed slow typing speeds and it's almost like lagging. Another thing I observed is that, when trying to run, for example, Factorio, black flashes are all over the screen, making any kind of gameplay unplayable and frustrating. Please, could you land me a hand of help and guide me to get through this behavior? I'm day 1 Arch user so please bare with me if I ask for a dumbed down version of how to do some commands or more explicit steps. I will provide any kind of info that is helpful and requested.
AMD Ryzen 3600x
Nvidia 3060
b450 mortar max

Edit: I have two monitors, 1 60hz and 1 144hz. Factorio runs without flicker on the 60hz  monitor, so I set the 144hz monitor to 60hz, runs well, no flicker. So I'm not able to run apps using 144hz. But the typing lag/stutter is still present (I checked on Brave browser and on Chrome browser). This could narrow the issue down.

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

We'll first need to know what you're actually running

loginctl session-status

and assuming it'S X11, please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General

Nvidia Linux drivers are bad at high refresh rates in my experience. Also use displayport, as HDMI seems to run worse than displayport at high refresh rates (if at all). My graphics glitches dissapeared when moving to AMD, although it also has some crashes.

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

Guys, before I tried to gather info using "loginctl session-status" I did a "sudo pacman -Sy" and rebooted. Currently booting stopped at "Terminate Plymouth Boot Screen" and won't proceed further so I need to figure what broke now before continuing with anything else...

Sitting in tty2 and looking at this error after I ran "systemctl status sddm" which says this in orange

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

First off, disable plymouth.
You'll most likely still be able to boot the multi-user.target (2nd link below)

But "sudo pacman -Sy" is inert, it sets you up for partial updates (don't) but will in and by itself not change anything about your system.

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

That's not a command but a kernel parameter.
Do not just copy bluebox text into an interactive shell, that's recipe for a disaster.

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

So good morning again Seth. Here I come with what I learned and tried. I also reinstalled Arch Linux as I nuked it by mistake. I learned I can enter Kernel parameters by going into my live USB key install, nano /etc/default/grub and typed the lines plymouth.enable=0 disablehooks=plymouth in between the quotes of GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" as per wiki example. Next wiki says:
And then automatically re-generate the grub.cfg file with:
# grub-mkconfig -o /boot/grub/grub.cfg

Now here is what next problem rises: when I hit enter this comes
/usr/bin/grub-probe: error: failed to get canonical path of 'airootfs'

Please tell me if I did anything wrong until this point as I'm learning while walking instructions.

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

Don't edit the grub config of the install iso, that's not going to survive a reboot anyway.
If you want to pass kernel parameters to the install iso, edit the kernel commandline in the grub menu.

However, since you re-installed arch(?) is the plymouth problem still there?
Why did you (re)install plymouth itfp?

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

So the reason I try to enter grub parameters on the install iso on USB key is that I understood I can't enter grub without iso USB key. How can I enter my grub without the iso, on my live arch (not desktop environment but you get what I mean, Im just dumb to know how to express specifically) to get rid of Plymouth and solve my graphical issues for good.

Why I reinstalled arch? Because I tried what I told you before and then encountered another issue at boot "arch linux stopped at reached target graphical interface" and I preferred to reinstall instead of dealing with issue number 1000.

Since I reinstalled which took a bit, hence my slow response, Plymouth is still a problem if I want to get rid of screen tearing, graphical issues,  as you said, I gotta disable it.

Note: After Linux reinstall, my system is live, I can use it, but can't play anything due to the graphical issues

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

I understood I can't enter grub without iso USB key.

That's nonsense.
You're not "entering" grub for this and you most certainly don't need to do it offline.

Start the system normally, when grub appears, select the Arch entry, press "e", find  the line that has vmlinuz-linux in it and append the plymouth parameters there.
If you want to disable it with a non-volatile config and cannot boot the installed system because of plymouth, you can edit the grub config after booting the iso, but you'll first have to "arch-chroot /mnt" into the installed system.

Edit: … and in that case, don't forget to mount the /boot partition before. But in doubt just edit the kernel commandline in the grub menu

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

As I assumed, yes, you're right, I'm doing nonsense, but I gotta ask you something first before doing what you told me.
My system boots (without the iso USB key in pc) in like 10 seconds, in this time I see no grub, it's just lines of code going down then log in screen appears. Could you tell me, please, what am I missing here?

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

Grub is the thing you get before the system boots, provided you installed it as bootloader. Did you? (Because otherwise this is all irrelevant, you'll have to edit the kernel parameters according to the bootloader you actually use)

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

Portrait mode, really? tongue
I can see "something" in probably the center of the screen, but can't make out what that is, then, probably after the KMS switch, boot messages appear, plymouth isn't used, it seems.
The system then seems to boot and the GUI shows up on the monitor to the left?

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

So Seth, I tried to film the whole booting process in slow motion because the lines of text were going too fast. Ianaged to get all the booting text here in 4 images:

Also, the output of  "loginctl session-status" is:

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

Why are you posting photos of text?
Afaict the problem where you couldn't boot at all is gone?

You're in a plasma/wayland session, started by sddm.

So returning to the original problem: do you encounter that when starting an X11 KDE session?
(Afaiu you can select the session in the lower right corner of the SDDM login screen)
What's the ouptut of "qdbus org.kde.KWin /KWin supportInformation"?
(Don't post a picture, you can just upload that following the tip in the first link below.)

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

The problem where I couldn't boot at all it's solved Seth, as I said, because I reinstalled Linux again so that's no more worries. And the photos I showed you are related to the video from which you couldn't figure out what bootloader I have.
Also the output of "qdbus org.kde.KWin /KWin supportInformation" is:

Update: Reinstalled 3rd time Linux, installed GRUB as bootloader and I nano the /etc/default/grub to insert the kernel parameters (I inserted GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet nvidia-drm.modeset=1 plymouth.enable=0 disablehooks=plymouth i915.enable_psr=0 i915.enable_fbc=0" these parameters)
So the parameters had no effect on the tearing/flickering problem which still occurs.

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

This has nothing to do w/ plymouth anymore.
Plymouth was only what apparently at some point prevented the boot completion.

The i915 parameters should™ be moot, too, since you're running X11 on nvidia.
Please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General

You've two outputs, 60Hz and 144Hz, the latter not on VRR.
Does the flicker/tearing remain if you
1. disable the compositor (SHIFT+Alt+F12)
2. set the 144Hz output to 60Hz
3. Remove one of the outputs
4. Enable VRR for the 144Hz output, https://wiki.archlinux.org/title/Variab … _on_NVIDIA
5. Run KDE on wayland?

Lastly: does the flicker and tearing happen on both monitors or only one of them? Which?

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

Excuse me as I forgot to add basic information about the problem such as: Both monitors had the flicker problem, doesn't matter if I game or watch a video. Refresh rate didn't fixed the problem. It occurred on both monitors, both 60hz, or one monitor 60hz.
Again, my apology as maybe I misinterpreted  but I assumed you wanted me to post the Xorg log, so I have to install Xorg effectively, which I did and now the flickering is not present anymore after I executed "sudo startx" in Konsole saw blackscreen, rebooted and flicker was gone. I tested Factorio to see if flicker is still present and it's not. 

Only major lag is present now on desktop animations/when moving windows, bringing windows from background to foreground and vice versa. I'm trying to deal with this issue now. I enabled VRR, disabled/enabled compositor but didn't helped.
I am running KDE  wayland since the begining of the issue, at least that's what it says when I choose it in the log in window from upper left corner but now chose X11 to proceed further as you said.
I removed the plymouth parameters from /etc/default/grub as you said it no longer helps to resolve a solved issue.
Also, if by "post your xorg log" you mean "run this command in konsole: tail -f ~/.local/share/xorg/Xorg.0.log | ts    which outputs

bash: ts: command not found
tail: cannot open '/home/submuffin/.local/share/xorg/Xorg.0.log' for reading: No such file or directory
tail: no files remaining
.

Edit: Nevermind, it's still present, haven't done anything but search the web to fix another problem and tried Factorio again, just to see the graphical tearing/flicker again...idk at this point what causes it. But on X11 it seems after a restart, my sudo nvidia-settings display all the proper setting tabs without any Konsole error as it does on Wayland.
If it helps sometimes I don't have this errors when I'm doing sudo nvidia-settings, sometimes it works, I don't know why it fails

Re: [Unsolved] Screen tearing, slow text input, screen flashing in games

Operation Mode: Xwayland

When you called "qdbus org.kde.KWin /KWin supportInformation" you were running KDE on X11 - also you cannot suspend the compositor on wayland, the wayland compositor is the wayland display server.

after I executed "sudo startx" in Konsole

Don't sudo that. Also "startx" will just get you a simple X11 server at best (trying to start xterm and twm) and then immediately terminate. (And quite possibly X11 won't start at all out of the wayland context)
You'd rather select KDE on X11 in your DM (SDDM, I assume)

The position of your Xorg log depends on how X11 is started, https://wiki.archlinux.org/title/Xorg#General
Most likely /var/log/Xorg.0.log

cat /var/log/Xorg.0.log | curl -F 'file=@-' 0x0.st

my sudo nvidia-settings

Do not sudo that either! In general, stop prepending sudo to things unless you *know* that you need to run something as root, and the rule of thumb is that you don't run GUI as root, period.
