After I change keyboard type, boot hangs before splash screen

On Kde settings, I change keyboard type from 85 to 105 keys and I activated the meta key in the shortcut settings.
On reboot, the system stuck on mouse pointer before the splashscreen appear.

Now, I’m writing from a live usb.
What is the file configuration to resetting the keyboard?
Can I do it from live? I can see my root partition.

I would be more precise:
I wanted to activate the META key for my laptop.

At first, in System > Input devices I click on ‘Advanced’ and 'Configure keyboard options" and I set the META key to left META (sorry, I don’t remember what is the exact option).
But it didn’t work. So, in Keyboard settings, I changed the “Generic 86 keys” to “Generic 105-key PC”
I reboot and I got the problem.
I think it is the first editing that hangs the boot (the META key did never work).

Maybe I could reset to default, if I knew where is the config file.
Any idea?

You are looking for /etc/X11/xorg.conf.d/00-keyboard.conf
Something of this sort:

Section "InputClass"
        Identifier "system-keyboard"
        MatchIsKeyboard "on"
        Option "XkbLayout" "us"
        Option "XkbModel" "pc105"

unfortunately, mine is the same to yours. Maybe the changes are not here…
How can I reset to default?

KDE Plasma stores that information in ~/.config/kxkbrc
Seems like i also have now Model=pc86
KDE Plasma defaulted all Generic to the Generic 86-key PC? Let me take a look at other installs i have and i’m sure i used to have the pc105.

What branch you are on?

Ok, thanks.
Stable branch.

Here my kxkbrc:


The modified date is compatible with the hour that I do the edit.

Maybe the two rows:


should be related to my changes.

There seems to be an inconsistency


On another install that Model entry is empty on my end, yet the settings display correct if i access the Keyboard Settings
Once on this install i removed the Model, as i have on the other install, and open both settings (the Keyboard is now integrated in the Plasma Settings under Input Devices) and Keyboard Settings = i get two different things between the two:

If you used the Keyboard from Input Devices then it might have a regression/bug, reason why it defaults and always displays the pc86, hence the Advanced Options get funky. Will have to investigate more about this.

yes I used the Input Devices.
Now, what can I do, please?
Delete the kxkbrc file? Is it safe?

No, deleting it might trigger the Input Device settings to take priority hence again making it as Model=pc86 instead Model=pc105 in a new file.
Just make that entry as Model= then reboot and hopefully the options you set will work, yet the system will take the correct pc105 from xorg config.

Ok, thanks for your help.

Can I edit the file from the live iso?

And should I delete the
row too?

You can edit it from your session, even from TTY with nano
from this:


to this


Not sure what this option does tho

and on my end is set to false

Make a test with your option and if doesn’t work then remove that line.

Thanks, I will try and report the result. :slightly_smiling_face:

@bogdancovaciu, I did the changes (I insert pc=86 too), but unfortunately, the boot didn’t arrive to desktop.
The system hangs on:
/dev/sda2: clean, 374339… etc
after the mouse pointer appears.

After I waited two minutes I tried to access to TTY, login and did the command startx, but I got the error:

xauth: timeout in locking authority file /home/user...... etc. and then the screen was black.

So, what can do now?
Maybe can I create a new user? Reinstall only KDE?
Please consider me almost a newbie.

That is unrelated to the keyboard issue, and means you have wrong permissions and ownership on your home user files and folders. Run this command to fix it:
sudo chown $USER:$USER $HOME
Reboot your system just in case after that.

No success! :sob:
Could do something from TTY, or I have to reinstall manjaro?
Any ideas?

Do this from TTY as your user:

mv .Xauthority .Xauthority_backup 

And then

xauth generate :0 .trusted

To be sure then run

systemctl reboot

After the second command and about 30 secs, I’ve got the same error:
xauth: timeout in looking authority file /home/user/.Xauthority

At reboot, same things.


I prepared to reinstall the S.O.
Whit a Live ISO, I did a total and long backup.
While I was at it, I resize the /home partition to create a new DATA partition and then proceeded to copy my personal file.
I predicted that this procedure would take many hours, so I shutdown my laptop.

The follow day, I wanted resume the job, but I forgot to insert the usb live iso.
I let the boot go on, ready to REISUB but, to my great surprise, my desktop appared again!!! :money_mouth_face:
Now, my system works like a charm. :relieved:

I should point out that the only thing I did was to resize the home partition.
Supposedly, the keyboard thing was not the culprit.

It would be very interesting to know what might have happened to learn more about the “Linux Universe”, fascinating but sometimes puzzling for me. :heart_eyes:

If any experienced user could try to explain what happened, I would appreciate it.
