When we install ubuntu on a netbook, everything works fine except keyboard, this will ne annoying as you need to carry external keyboard always with you to work. So, here is a fix to it.
I have taken reference from this link Here
#include
#include <sys/io.h>
#define I8042_COMMAND_REG 0x64
int main(int argc, char *argv[]) {
char data = 0xae; // enable keyboard
ioperm(I8042_COMMAND_REG, 1, 1);
if (argc == 2 && argv[1][0] == '0')
data = 0xad; // disable keyboard
outb(data, I8042_COMMAND_REG);
return 0;
}
</p>I have copied the C program from above link to a file named keyboard.c
Following steps will help you compile the code and run it on boot time which eneables keyboard as soon as you start your computer.
1. Compile the C program using #gcc -o keyboard keyboard.c
2. Copy the output file to your desired location (/home/superman/keyboard)
3. To run the keyboard on startup we will set a init script in /etc/init.d/keyboard with following:
``` #!/bin/sh -e
### BEGIN INIT INFO
# Provides: keyboard
# Required-Start:
# Required-Stop:
# Should-Start: checkroot
# Should-Stop:
# Default-Start: S
# Default-Stop:
# Short-Description: Load the modules listed in /etc/modules.
# Description: Load the modules listed in /etc/modules.
### END INIT INFO
exec /home/superman/keyboard 1
```
4. Add following code to /etc/init/keyboard
``` description "Fixing keyboard issue in lenovo ideapad"
start on runlevel [2345]
stop on runlevel [!2345]
exec /etc/init.d/keyboard
```
5. Final step run the following command to update
``` sudo update-rc.d keyboard defaults
```
#### From next boot your machine gets booted with keyboard enabled
