[SOLVED] Mouse and display flickering

Background: At first, I installed Arch Linux in a laptop(resolution should be 1920x1080) with a SSD, every thing works fine. Later I need to change to another laptop(resolution is 2880x1800), But I don't want to reinstall a fresh new Arch Linux and reconfigure all the things. So I unplugged the SSD and plugged it into the new laptop.

There isn't any errors when system booting, any thing looks fine except the fonts is a little small. But when I open System settings and click the items on the left, the click not work,it seems there are some offset . When i move the mouse around  the display settings, the setting windows starts blinking, if I maximize the window, all the contents of the window blinking.
I am using KDE Plasma, the task bar also blinking some times.:(

It seems the mouse or the display need to calibrate? But the mouse works perfectly in firefox and konsole.

Is there any idea?

Re: [SOLVED] Mouse and display flickering

Is this KDE on wayland or on X11?

Re: [SOLVED] Mouse and display flickering

Start by posting the output of "xrandr -q" and your Xorg log, https://wiki.archlinux.org/title/Xorg#General and then "xinput list-props #n" w/ "#n" being the ID of the touchpad ("xinput list" gets you a list)

Re: [SOLVED] Mouse and display flickering

It do seems related with xorg, i install gnome and run gnome on xorg, same problem with gnome settings, but things solved if i switch to gnome on wayland.

xrandr -q: log
The Xorg log: log
xinput list 12: log

But I want to run KDE on Xorg.

Re: [SOLVED] Mouse and display flickering

There's neither input mapping nor output scaling and what you describe sounds a lot like flicker, so

Step #1: remove xf86-video-intel, report whether the issue remains

Wow, bro!!! It do the trick. But why do I need to remove the xf86-video-intel? My laptop is intel platform and there isn't any other
graphic card. Is  xf86-video-intel for independent intel graphic card?

Re: [SOLVED] Mouse and display flickering

https://wiki.archlinux.org/title/Intel_ … stallation - blue note.
It's phased out and causes lots of troubles on esp. newer IGPs
You'll be running the modesetting driver that shifts the workload to the i915 kernel module and is more akin to what als wayland does.

Re: [SOLVED] Mouse and display flickering

Very appreciate! I didn't expect it was caused by the new IGPs.
