I just installed - and updated - Fedora 17 on my vaio VGN-CS170F laptop. Everything works fine, except when I close the lid it goes to sleep, and when I open it back, the keyboard becomes unresponsive (the mouse pad works just fine).

I'm running

 Linux vaio 3.4.4-3.fc17.x86_64 #1 SMP

Any hints ?

You are using the built-in keyboard, correct? –  imtheman Jul 5 '12 at 21:17
    
That's correct. –  xain Jul 5 '12 at 22:19
    
Do you know whether the keyboard is using a special kernel module? You can use the lsmod command to check what modules are loaded. –  Izzy Jul 6 '12 at 13:02
    
A pity there is an unresolved forum post for this at forums.fedoraforum.org/showthread.php?t=272752 :/ –  invert Jul 11 '12 at 9:51

That seems to be a bug with your keyboard. Here's the solution I found:

To automatically rebind keyboard after resume, open your /etc/default/grub file with your favorite text editor and and append atkbd.reset to the kernel line, like this:

GRUB_CMDLINE_LINUX="... atkbd.reset"

Don't forget to run grub2-mkconfig. Consequently, the system will take care of resetting the driver on resume.

Did what you said with no luck; anyway the modules loaded are in pastebin.com/jMNQicCz. Thanks –  xain Jul 6 '12 at 22:50
    
Sorry to read that. I also checked your modules list, but found nothing which looked like pointing to your kbd. If it were, you could have tried to mark that for automatically unload (on sleep) and reload (on wakeup), using the SUSPEND_MODULES setting. –  Izzy Jul 7 '12 at 20:26

Not at all sure if this will help, but seems like certain kernel versions had suspend/resume issues. As a test, try adding acpi_sleep=nonvs to your kernel line on boot, and try suspend/resume.
