Ubuntu 8.10 running in Low Graphics Mode (Intel 945)

Today when I started session on ubuntu 8.10, error messages appeared about x server ...

My 1440 x 900 resolution is broken, since then I'm trying to recover it without success.

The system is running in Low Graphics Mode, the option showed to try with "create a new configuration" does not works and always, after restart, is running in low graphics mode, the graphic card is an Intel 945 on board (asrock wolfade motherboard)

Also I tried with:
Code:

marcelo@linux:~$ sudo dpkg-reconfigure -phigh xserver-xorg
[sudo] password for marcelo:
xserver-xorg postinst warning: overwriting possibly-customised configuration
   file; backup in /etc/X11/xorg.conf.20090327003239
marcelo@linux:~$ sudo dpkg-reconfigure -phigh xserver-xorg
xserver-xorg postinst warning: overwriting possibly-customised configuration
   file; backup in /etc/X11/xorg.conf.20090327003259
marcelo@linux:~$

And:
Code:

marcelo@linux:~$ xrandr --output VGA --mode 1440x900 --rate 60

but nothing works...
Code:

marcelo@linux:~$ xrandr -q
Screen 0: minimum 640 x 480, current 1280 x 1024, maximum 1280 x 1024

Is there a way to recover the 1400x900 resolution that always I used?

This happened today when I logged on GNOME.

I really appreciate any help.

Note: the graphics was working perfectly with compiz effect, but suddenly this problem appeared.
