Hi again. Thanks for your help. I tried using YOU to install the nvidia driver. Let me explain how it didn't work. My monitor has a resolution of 1400x1050, and this is how I like to work. But after I finish the YOU procedure for the instalation of the nvidia driver, the resolution was set to the lower value of 1024x768. Besides, the text console, even if it wasn't out of sync, was not satisfactory, it showed many regularly spaced white stripes. Wen I set the resolution up again to 1400x1050, I got again the syncing problems. Any comments appreciated, Ze ______________________________________________________________ Departamento de F�sica http://www.dfisica.ubi.pt Universidade da Beira Interior http://www.ubi.pt ______________________________________________________________
