Gnome freezes frequently when doing anything

[Alexandre]

With Jauntuy (All updates installed) Gnome frequently freeze. There is no specific application that Im am working with.
Sometimes freeze on selecting Themes, Running a terminal, Editing with gedit, surfing on internet, editing with OO, etc.

I am unable to use the keyboard to swith to a terminal (CTRL+ALT+F(n)) and restart GDM. I Can only reboot with the combinations: Ctrl+alt+SysReq+S then Ctrl+alt+SysReq+B

It is an Acer Laptop (Aspire 5720z) with 2Gb RAM, Intel X3100 Video, Atheros AR5007 Wireless card

Thanks for taking the time to make Ubuntu better.

During a freeze, please try RIGHT ALT + SYSREQ + K and let us know if it restarts X for you.
If it works, then it's an X issue. If not, then it would seem to be a kernel issue.

If it's an X issue, please attach your X server configuration file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.0.log) to the bug report as individual uncompressed file attachments using the "Attachment:" box below. Could you please also try to run without any /etc/X11/xorg.conf and let Xorg autodetect your display and video card? Please also attach the /var/log/Xorg.0.log from this attempt.

If it's a kernel issue, then please include the following additional information, if you have not already done so (pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" after a fresh boot and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.
The full description of procedures for kernel-related bug reports is available at https://wiki.ubuntu.com/KernelTeamBugPolicies

Thanks in advance!

Hello, RIGHT ALT + SYSREQ + K tried to restart the X, but All that I got was a blank screen with a lot of HardDisk activity for more than 1 minute, then nothing happened.
Before try that key combination when gnome froozes I just cant control with mouse and keyboard, but rythmbox kept playing, and Pidgin kept receiving Instant Messases.

The feezes reduced the frequency in last days.
Now I will try to remove the xorg.conf and see what happen.

$ uname -a
Linux alexandrelaptop 2.6.28-11-generic #41-Ubuntu SMP Wed Apr 8 04:38:53 UTC 2009 i686 GNU/Linux

I think it may be related with https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/363821 and https://bugs.edge.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/359392

Sintoms seems a little bit different but, since compiz was disabled my freezes reduced 99%, and I re-activated compiz for a while and in about 2 hours I got a Freeze. :(

Get previous version of intel driver may resolve these issues
