** Description changed:

  occurs in: Karmic and Lucid
  hardware: Sony Vaio laptop

  problem:
  1-4 times a day, the keyboard will stop working. The mouse will still work though. To fix this requires either a hard-reset, or navigating to the logout button, and logging out and back in. Novice users, or users who do not use the mouse, or who are not using a desktop environment that allows saving with just the mouse, will lose their work. Unsaved files will require the user to save them using copy-pasting with the mouse.

  After a few months of this problem, I noticed that holding down a key
  causes it to autorepeat. Thus, the keyboard is just broken "on
  keypress". For example, to type "testA", it would take about 10 seconds,
  and I would have to hold down t and let go the moment autorepeat
  started, then the same for e, then the same for s, then the same for t,
  then hold down shift for about a second, then hit A and lift up before
  autorepeat starts.

  There doesn't seem to be any useful information in /var/log/Xorg.0.log
  or or /var/log/messages or dmesg, though I haven't checked extensively.

  Rarity: unknown
  Severity: absolutely infuriating, happens constantly, and is a major hassle and possible source of data loss for many users

+ WORKAROUND:
+ - open the System Settings > Accessibility (or type "kcmshell4 access" in a terminal)
+ - under "[tab]Keyboard Filters" you may see Sticky Keys enabled if you are suffering from this; disable it and hit Apply
+ - to prevent this from happening again, go to "[tab]Activation Gestures", disable "Use gestures to activate...", set the inactivity timeout to the lowest possible setting (1min), and enable all the notification features
