If your keyboard and mouse doesn’t work on your laptop in ubuntu .

June 4, 2010

Well , I have this lenovo laptop . When I installed ubuntu 9.04 on it , sometimes I observed that after booting the system where the login screen appears my inbuilt keys and keyboard would freeze . To fix this i would restart it again hoping it would go away .

Thankfully it working almost everytime 🙂 .  Anyway a few days ago i found a permanent solution to this problem . So if you too are facing this problem do the following :

  • Go to /etc/grub . There you will find this file called ‘grub.cfg’ .linux
  • Find the line that looks something like ‘linux /boot/vmlinuz-2.6.32-21-generic root=UUID=848fb107-a42a-4755-b995-6566febd47df ro   quiet splash ‘
  • Now append ‘i8042.reset’ to the end of this line .
  • Now the line looks like
    ‘linux    /boot/vmlinuz-2.6.32-21-generic root=UUID=848fb107-a42a-4755-b995-6566febd47df ro   quiet splash i8042.reset ‘
  • You are done 🙂

PS – This works for every version of ubuntu . You just have to find the grub.cfg or similar file if it is not there. On some versions it   is the ‘/etc/grub/menu.lst’ file.

PS – This is my first post on this blog . I didn’t know what to write so decided to start with this 😛
