it's always worth backing it up just in case. After you've saved it just reboot the machine (or restart gdm) and then you'll see if it's worked.<div><br></div><div>Worse case scenario is that the display manager will fail to start and you'll be left at a flashing cursor. from there you can do the following things to recover:</div>
<div><br></div><div>sudo cp /home/rene/xorg.backup /etc/X11/xorg.conf - this copies your backup file back into the correct location then do</div><div><br></div><div>sudo /etc/init.d/gdm restart - this will restart the display manager and hopefully all is good. </div>
<div><br></div><div>The nuclear option is </div><div><br></div><div>sudo rm /etc/X11/xorg.conf && sudo /etc/init.d/gdm restart</div><div><br></div><div>This will delete your xorg.conf and the restart the display manager, when it restarts it should automatically recreate the xorg.conf</div>

Thanks for all your support and information given I'm still reading and<br>
doing the homework.<br>
<br>
Dan you send me this link:<br>
<a href="http://samiux.wordpress.com/2009/05/15/howto-via-s3-unichrome-pro-problems-fixed-on-ubuntu-9-04/" target="_blank">http://samiux.wordpress.com/2009/05/15/howto-via-s3-unichrome-pro-problems-fixed-on-ubuntu-9-04/</a><br>
<br>
I opened the xorg.conf in gedit and put this lines<br>
<br>
Option "PanelSize" "1024x768"<br>
Option "sw_cursor"<br>
Section "Device"<br>
Identifier "Configured Video Device"<br>
Option "PanelSize" "1280x800"<br>
Option "sw_cursor"<br>
EndSection<br>
<br>
is selecting "save" all I've to do and changing the resolution should be<br>
done?<br>
<br>
I put the correct screen size in which I took from my own laptop as this<br>
is the same size only the refresh rate shows 60hz on mine and on the<br>
fujitsu when selecting the same resolution in<br>
"Display Preferences" the refresh rate stay's at 0hz.<br>
Is it necessary to back up the old settings before changing the<br>
xorg.conf?<br>
<br>
regards<br>
Rene<br>
