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.
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.
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.
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.
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.
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!!!
Now, my system works like a charm.
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.
If any experienced user could try to explain what happened, I would appreciate it.
