Dear Luca, As your comments hinted at a misconfiguration and it had been a very long time since I had used that machine, I ran a live jessie debian distribution and the X-windows system worked with the nvidia driver, but only in the failsafe mode. I decided then to make a fresh install of jessie and later upgraded to stretch. I haven't installed nvidia yet, but nouveau hadn't worked and it is working properly now, so the crisis of my T61 is over. I still don't know if nvidia-legacy would work now in my machine. I'll try it later. Thanks. Luis
