Public bug reported:
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
