Re: How can I disable the keyboard on my Notebook?

I am very worried that the fast boot will lead me into a dead end so that I can no longer access my boot menu with my handycap. I am having difficulty navigating the boot menu. The keyboard constantly spams the right or tab key and switches me to the next menu bar every second. Do you have a terminal command to list the devices first. Then I need a command to turn off the selected driver.

I have already done this and could not start the notebook afterwards. The power button is on the keyboard next to the * symbol.
I dropped water on the keyboard since then I have the problems.

>>Do you have a terminal command to list the devices first. Then I need a command to turn off the selected driver.

Since the driver is a kernel module, you have to use lsmod to list all the modules the kernel and has loaded, find the driver for your laptop keyboard and blacklist it.

Since module names aren't exactly descriptive, you have to use modinfo to see their description.

You can use this little command to get a list of descriptions of all the kernel modules:
Code: [Select]
lsmod | grep -v '^Module' | cut -d' ' -f1 | while read -r module; do printf 'module: %s\n%s\n\n' "$module" "$(modinfo $module | grep description)"; done

See which module matches the description for your internal keyboard and blacklist it.

This is how it looks to me. Question for the pros. What is the name of the module for the internal keyboard? I have now hoped that it contains atkbd or kbd in the name. How can I blacklist the module then?
