With my DELL Optiplex GX260 the Imbedded Intel 845 Graphics has "Known" 
Driver Issues when Graphics Acceleration is Enabled, this might be your 
"Problem" as well???  Although I had posted to DELL's Linux Desktop Group, 
I can NOT find that within DELL's archives so I will Cut & Paste what I 
had Post to DELL's Group (DELL sells Ubuntu Pre-Installed now!!!):

Turns out this is a "Known Issue" with the Intel 845G Support contained
within Xorg's Intel Driver (the 845G worked correctly with Hardy's i810
Driver, which has been replace with a more General Intel Driver) and
misbehaviour with "compiz":

Taken from Ubuntu 8.10's Release Note:


Hangs with desktop effects on Intel 830MG and 845G video cards

There is a bug in the Intel video driver for the older intel 830 and 845
integrated video cards that are used on laptops like the IBM R30. Desktop
effects with compiz will not work on those chips and will freeze the system.
For new installations, please install using the safe graphics mode (press F4
in the startup screen) on these systems and disable desktop effects via
System -> Preferences -> Appearance, clicking on "Visual effects" and
choosing "None".

Although there is an Update for the Intel Xorg Driver (2.4.1-1ubuntu10.3),
for me it did NOT resolve the issue!!!  One Solution I found was using
"gconf-editor" to switch GNOME's Window Manager from "compiz" to 


A Second Solution was removing the "compiz" and "compiz-core" packages:


Although both of the above worked for me, personally I would prefer to see
Xorg "Fix" their Intel Driver so that it correctly supports the Intel 845G
and "compiz" could be re-instated as GNOME's Window Manager!!!
