Everaldo, there are a couple of things you could try to help gather
further information to help us figure out how much the drawing
operations are actually slowed down on you system. Also you could try
some tweaks to get back to better speed.
1.) Enable the "Benchmark" plugin of compiz. To do that make sure you
have installed ccsm and the benchmark-plugin:
sudo apt-get install compiz-fusion-plugins-extra compizconfig-
settings-manager
2.) Start ccsm from a gnome-terminal and fire up ccsm:
ccsm
3.) Use the seach-filter in the top-left corner of the ccsm-window to
look for "bench". That'll limit the visible plugins to only the
"Benchmark"-plugin. Tick the checkbox to enable it.
4.) Now press the default key-board-combo Super-F12 (or Meta-F12,
Super/Meta is usually the key with the "Windows"-label on it). Note the
framerate shown in the overlay that'll fade in. Let the overlay settle
for a moment
5.) Repeat that on the Jaunty system you mentioned.
6.) Since you're on an intel i965 (GMA X3100) check if you have the
XRender-method "UXA" enabled. To do that execute:
grep UXA /var/log/Xorg.0.log
That should, if you have UXA enabled, output something similar to:
(II) UXA(0): Driver registered support for the following operations:
If you don't see this line you're not using UXA and have the option to
enable it by adding to your /etc/X11/xorg.conf (create it if you don't
have it) the "AccelMethod"- and "DRI2"-lines:
Section "Device"
Identifier "Configured Video Device"
Driver "intel"
Option "AccelMethod" "UXA"
Option "DRI2" "true"
EndSection
The above is just a short example of what it could look like. I don't
know if you've ever messed with /etc/X11/xorg.conf. This could help you
get some of the speed back.
