Hello, I have been using zorin os for some time now but it seems that there is a problem where when im watching a video or when i shake a window fast, I get screen tearing.
I tried adding the TearFree flag on /etc/X11/xorg.conf.d/20-intel.conf but it didnt help alot as it removed the tearing but my screen got slower. I also see that whenever I connect my charger to my laptop, the speaker sound becomes distorted and the tearing becomes more visible alongside slowness. I have to note that I use fractional scaling
Can anyone help me?
I also called hp who where unable to help me as he knew nothing about linux and the hp hardware diagnostics tool only ran on windows
I have an HP Laptop 15s-fq5916nv
Are you using Wayland or Xorg Windowing?
(I am guessing from "TearFree flag..." it is X11, but you also mention fractional scaling which hints at Wayland)
Is the charger the original one supplied with the laptop?
Small compact switch mode PSU's can create interference (EMC).
I use xorg and gnome settings allow me to use fractional scaling, And yes its the original charger out of the box
OK. Thanks for clarification.
I remember someone else having sound or display issues only whilst charger was connected. I have tried searching the forum for that case, but not been able to find it yet.
Is the laptop always performing OK at times when not connected to charger?
it is performing that way only when charger is connected
When i changed to wayland it had no screen tearing but some apps where blury
I now found the other thread. It was originated also by you: Slow down and distorted speaker audio in zorin os 17.3
Noone could give a solution to that thread, so I doubt if one will be found now.
FYI. I have also done some websearches using "...Ubuntu" in searchterm to try and help you find an answer, but again no solutions found.
If you are dual-booting, does that charger cause any issues when running Windows?
Maybe someone will have a bright idea, but I am unable to think of anything except try another charger. But probably that will be the same.
Thank you, as for the screen tearing I tried changing the resolution to something smaller rather than use fractional scaling but it made the display quality worse... Can atleast fix that?
Maybe try installing some drivers or tweaking the display driver?
Quick question: When charger connected, does the laptop run hot?
no it doesnt, would you think taking my laptop to a technichian to change my gpu to amd will my problems? especially the screen tearing xorg and blurriness on wayland? becuase I' ve heard that intel gpus dont end well with freetearing flags.
As for the sound, do you think It may be a hardware problem as well?
I posted about your sound issue in the other thread you created, and stated that Windows users were having the same issue:

It appears the sound issue has something to do with ACPI software. You could amend your GRUB configuration file to add:
ACPI=off
The downside to this is that your battery life might be affected in respect of Usage time between charges.
