KDE not logging in

Hello,
KDE was installed and was working perfectly fine on my hp laptop but I wanted to have touchpad actions available so I followed this guide on wiki.arch.   https://wiki.archlinux.org/title/Touchpad_Synaptics

After I saved the file and reboot the laptop, the KDE wont start

I stll have acess to terminal using ctrl+alt+f2 and I tried using the command " kstart plasma-wayland-desktop"

But then it shows
[

qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin could be inotialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimalegl, offscreen, vnc, wayland-egl, wayland-xcomposite-glx, xcb.

Aborted(code dumped)

]

I wonder if the problem would be regarding the touchpad file I created in /etc/X11/xorg.conf.d
Beacuse before that kde was working perfectly fine...
Now as I start my laptop the KDE doesnt load , and I only have access to terminal

Thank you for helping

It does seem likely.  Please post the contents of the file you created as well as Xorg.log.  See pastebin to post the files contents from the console.

Re: KDE not logging in

Filename:

/etc/X11/xorg.conf.d/70-synaptics.conf

File content:

Section "InputClass"
    Identifier "touchpad"
    Driver "synaptics"
    MatchIsTouchpad "on"
        Option "TapButton1" "1"
        Option "TapButton2" "3"
        Option "TapButton3" "2"

Re: KDE not logging in

Xorg will be in either ~/.local/share/xorg/ or /var/log.  You did not find the examples in the subsection Without a dedicated client?
Please also use code tags.
Edit:
Does the .conf literally contain at the end:

        ...
EndSection

Re: KDE not logging in

If you've been pointed to a resource to help you with our standards you're expected to read and apply them the next time.

You shouldn't copy example files literally. Chances are you don't need the majority of these options and/or that they are actually incorrect for your device. The ... is for when you'd want to add additional parameters not yet listed and would definitely be wrong and break xorg.

The minimal necessity for switching to the synaptics driver is

Section "InputClass"
    Identifier "touchpad"
    Driver "synaptics"
    MatchIsTouchpad "on"
EndSection

Everything else is additional and potentially optional information.

Re: KDE not logging in

I would make sure to be careful next time...

But even after editing the file as u said
KDE wont start

As I start my laptop
It says
[

Starting version 250.4-2-arch
/dev/sda5: clean, 348130/2293760 files, 3382618/9175040 blocks

]

I still only have access to terminal

What steps in the terminal I must follow to start kde as ,It says KDE is already installed

Is it fine to remove kde and start over again?

Re: KDE not logging in

Nope, atm nobody knows what went wrong so there's no guarantee this won't happen on a new install.

Also the error is unlikely to be with kde itself.

create a xinitrc file for your normal user as described at https://wiki.archlinux.org/title/Xinit#xinitrc
install the packages mentioned there, then run startx .

It should show 3 terminals and a clock on screen, if it doesn't that means basic X setup is wrong .

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky
