screen out of sync

Hello! I have an Asus L5000 laptop with a nVidia GeForce FX graphics card and things are running reasonably well. However, wen I press [Ctrl][Alt][F1] to escape the X environment into a text-only interface, my screen gets out of sync! Does anybody know of a simple fix to this? Thanks, Ze ______________________________________________________________ Departamento de F�sica http://www.dfisica.ubi.pt Universidade da Beira Interior http://www.ubi.pt ______________________________________________________________
