Laptop keyboard stopped working

Question

I have a defined ElevatedButton, how to assign onPressed listener to another function? something like this -

button1.onPressed() => log("something else");

 Widget button1 = ElevatedButton(
    onPressed: () => log("something"),
    child: Text("name"),
  );

thank you!

Solution 1

try this, it my help you fix your problem:

Install the drivers:

sudo apt-get install xserver-xorg-input-all

If already installed, reinstall it:

sudo apt-get --purge autoremove xserver-xorg-input-all
sudo apt-get install xserver-xorg-input-all

Reboot and try again if everything is working.

Solution 2

Try this So, to fix this, go to:

System Settings → Universal Access → Typing (tab): switch off "Slow keys"

Also switch off "Enable by Keyboard" if you want to stop it happening again.

It don't know why the login screen ignores this setting, tho.

Update

I just did this again (d'oh!) which brought me back to this answer and gave me the initiative to find out what triggered it.

Apparently, if you have Enable by keyboard on and then you hold down the Shift key for eight seconds, it will enable/disable slowkeys.

This was a new setup, and I had enabled Enable by keyboard because I wanted a way to flip between touchscreen and keyboard mode easily. Might not be worth the effort, tho!

Thanks to tudor, I guess. All keyboards stopped working after login screen

Thanks! When I upgraded my Ubuntu studio to version 17.04, my keyboard stopped working, so I logged in by ssh and installed xserver-xorg-input-all. Worked like a charm, thanks a lot.

I had the same issue, only the touchpad was working. The ubuntu virtual keyboard saved me, after a sudo apt-get install xserver-xorg-input-all and a reboot, everythings came back to normal

Happened to me after switching back from windows for the first time in a while on a dual boot

Happened to me after trying to switch from Nouveau to Nvidia's proprietary driver via Linux Mint's (19.3) driver manager. The installation failed and left xorg in limbo. No mouse, no keyboard... as soon as the DE got initialized. Via Grub's Recovery Mode and these commands I was able to reset everything back to normal.
