Grats on the solve!
I see that you have a D630... can I ask how much memory you have in that machine? I was never to put more than 2GB :-(, think it's hardware locked I read somewhere, so just checking.

Yes, TC is a mine of info; so good to have people like this around; also if noone else gives me an answer TC usually does 
The 640x480 issue was on a fresh install on a laptop someone gave me for free (Packard-Bell MX37) earlier this week. LL3.8 64-bit runs on it brilliantly.

Turning to the Dell: when I bought it 2nd-hand in 2016 (from Amazon) it came with 4GB pre-installed, which is overkill for my needs; 2GB would have been ample. Just now I contacted Crucial.com re. RAM: they told me that with this Dell model the max you can install is 8GB.

Hardware locked? I don't know anything about hardware-locked PCs, but if RAM's expandable, can't you unlock it (though I don't know anything about this)?
