Bug Description

I have only 3 apps open : Firefox, aMule and Xchat but after 10 minutes after
open session I have this with tail -f /var/log/messages :

Nov 13 21:56:12 localhost kernel: [4328600.298000] atkbd.c: Unknown key released

does the CPU usage decrease if you close any of the three apps? i'd suspect
firefox, mainly.

There is certainly a problem with Firefox, IMHO. I have a similar problem
(though not
as severe) of Xorg slowly increasing CPU% and Mem use, like going from 2.5% to 7.5%
CPU usage, and increasing total Mem from 220MB to 400MB, in a couple of days. Only
programs running all the time: Firefox, Evolution, and Liferea. When I use Epiphany
instead of Firefox, then this CPU/Mem increase does not happen...

BTW, top shows a varying mismatch between system up-time and TIME+ for Xorg: my
current up-time is 12:48, while Xorg shows TIME+ 35:40. Before my most recent
reboot,
the system up-time was 3 days, and Xorg TIME+ 400 hours... The OP also shows a
mismatch between up-time and TIME+ for Xorg -- could this indicate a (related)
problem?

the 'time' field is cpu time, not wall clock time.

This looks likely not to be an xorg bug (and/or hard to track down as such with the available info). Much has changed in both xorg and Firefox since breezy. If the problem persists in dapper please try to isolate the guilty application and open a new bug against that. Thanks.
