The reference to trying vesa was the clue. Rather than try it any more complicated way, I booted Puppy, and where it asked me whether I wanted to go with Xorg or chose vesa, I said vesa. And it booted fine. So then, out of interest, I rebooted and chose Xorg. This time a message came up that the graphics card was fine and had been recognised, but Puppy was getting no feedback from the monitor, and would I chose what I wanted manually from a long list. I chose, and Puppy booted without a problem in full GUI mode. So I then tried to copy the relevant parts of the Puppy xorg.conf into the installation of Lenny that I currently had on the HDD. I just got myself into a mess. So I tried an xorg.conf that I had saved for permanent reference, that worked for another monitor, that I knew to be very similar. All is now well. Presenting problem solved. Though the question remains: what went wrong, where, that suddenly the monitor was not recognised. Thanks! Lisi
