Hi all,

3-4 days back i did a world emerge. First i wanted to do a update only but
instead a did a world emerge with --emptytree option. Everything gone quite
smoothly.
  Then i did a module-reubuild. Then a reboot. Everything was fine till now.
But after login i noticed one thing, typing anywhere(either on terminal or
gedit or anywhere) is not smooth any more.
  I mean going through in a file up and down or escaping characters is
really slow now.  One more thing was that 'gsynaptics' was not working
anymore.
-----------------------------------------------------
flukebox@flukebox ~ $ gsynaptics

** (gsynaptics:31184): WARNING **: Using synclient
flukebox@flukebox ~ $
----------------------------------------------------
It appread on screen for few moments less then 2-3 seconds and gone.  No
errors to trace back.
That sucks me totally. Previously i have xorg-x11-7.2, now after world
emerge I have xorg-x11-7.3 with x11-drivers/nvidia-drivers-173.14.09 both
the times. I didn't find a cure for that rough typing and synaptics.
Then i look inot Xorg log, and quite interestingly found  following errors.

-------------------------------------------------------------------------------------------
flukebox flukebox # cat /var/log/Xorg.0.log|grep EE
        (WW) warning, (EE) error, (NI) not implemented, (??) unknown.

In my Xorg.conf i have following related settings..

After that i googled a lot but till now unable to find any cure. So, i
forget that for time being.

Lately i was trying to get hibernate, suspend working on my laptop. I
followed "http://gentoo-wiki.com/HOWTO_TuxOnIce". I installed
"sys-kernel/tuxonice" and got settings accoring to howto.
I emerged hibernate-script,suspend too. then i tried hibernating. Aah
hiberanting didn't work. It worked partially actually. I am able to
hibernate but not able to resume. While resuming system freezes after saying
"cleaning". Any specific logs to look into ?
when hibernate didn't work .. i give a try to suspend .. and write
"hibernate-ram" on terminal and voila it worked. So, I am currently able to
suspend.
Here comes very interesting and strange part of all of these headaches.
After resuming from sleep, one more problem got solved. No more slow typing
hurray :P.
So, now i can type everywhere(terminal or gedit or whatever) as fast as
before emerging world. Even going though in a file up and down, tho and fro
are smooth now. But i have no clue whats happing wrong in boot that causing
me typing error.And whats good happing while resumming from sleep that
remove those error. Does sequence of module probing gives any change ??
