Public bug reported:

Binary package hint: xorg


Intermittent problem - Mouse/keyboard unresponsive (Number lock/caps lock cannot be switched off/on) and No signal input check cable – message on monitor 

I am new to Ubuntu (been a windows power user for too many years!).
Installed Ubuntu with dual boot of windows 7 RC in November 2009.
Difficult to know what started causing it and not aware of changing any
settings or updating system prior to it occuring, although always update
via update manager when it appears.

Frequency it occurs - varies, sometimes nothing for days then once a
day. Does not happen more than once a day, but is annoying when it does
occur (almost turned me back to windows for which I have never had it
freeze on me!)

At first thought it only happened when running torrents, but recently
happened even when not running torrents and had k9copy open. Always have
firefox open and Banshee media player.

I now believe this is related to xorg and Intel GMA/driver? Could also
be something to do with monitor powersave function (set to turn off
monitor after 10 mins)?

Attached messages logs for problem that occurred on 2 and 3.2.10 with
items highlighted in red that I feel are related. Always seems to freeze
after following messages in log?

Note for 2.2.10 after log of Feb  2 20:59:02 (item marked in red) will
see where I removed the NIC cable and moved lots of USB cables around to
see if unfroze. It did not but at least from log can see that the log
was working ok even if the keyboard, mouse and screen were unresponsive.

Frozen PC steps taken file attached - gives detailed information on
times when frozen and steps taken, etc

I hope you can enlighten me as to what is happening here and let me know
if you require any further information.

Thanks
