On a Sony Vaio VGN CS21S the keyboard doesn´t work after suspend to ram. Suspend to disk (hibernate) works though. Running a fresh install of Natty with Unity.

  • I've tried using adding "atkbd.reset to /etc/default/grub after the "quiet splash". This fixes the keyboard problem but now the touchpad is not responding any more. – davorao May 06 '11 at 18:34
  • After 11 years, I'm still having the issue and can't find a workaround... – Tom Jul 26 '22 at 16:23

The actual solution to this problem is:

Edit /etc/default/grub and change the line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash atkbd.reset"

Then, run update-grub and reboot.

Works for me on Lenovo Thinkpad X230.

  • Same here linux 5.9.3, Sony Vaio SVE 1512, suspend to ram → keyboard defunct; suspend to disk afterwards makes it functioning again.
    Loading the module atkbd with the option reset=1 (in case if it is statically compiled into the kernel, adding atkbd.reset=1 to the boot command line) did solve it.     – Golar Ramblar Nov 23 '20 at 16:59

Same notebook and same problems here.

I'll suggest you to take a look at this! http://techiesurgeon.blogspot.com/2011/05/get-beautiful-ubuntu-natty-running-on.html

In addition to your fix it suggests to add psmouse to /etc/modules so to address touchpad issue.

It worked fine for me.
