Hi Felix, Thanks for your input. I tried the video= and it made no difference. However, I did discover that removing "quiet" creates a lot more output. Funny that, isn't it? Quite nice too! I should probably have mentioned earlier, that if one launches X and then quits X to return to the terminal, the monitor does not turn off again, howeer, the mode is a bit crazy. It appears to display 80x25 but when one starts a new line at line 25, you do not get the usualy scrolling behaviour, things just appear to get printed out "below the monitor" if you know what I mean. Eventually the screen does scroll but after maybe 200 lines or so and it does so in a big jump. I seem to recall reading that the Nvidia driver was a bit cavalier and reinvented various parts of X, so I wondered if there was some crazyness whereby starting X started some of a necessary components of the driver. Checking the output of lsmod, as well as ps for anything nvidia related doesn't appear to be any difference between before X and after X. I'm also pondering if it's something to do with the port it's plugged into. The card has 3 DP ports and 1 HDMI. Two have displayed plugged into them. That said, the UEFI manages to output to a screen and so does Grub / Kernel, so does X, so one would imagine the bit in the middle might get it right too? Any ideas? Kind regards, Mike.
