We have some serious patience with this thing. I think everyone else evacuated. The reinstall wasn't likely to lead to a resolution but I did get to fix the partition boo boo. It's hot here. I took a nap. I did walk to the mailbox and get my mail first. My little 4 volt battery came in for my spare electric fence charger, keeps the deer out. Anyway, when I woke up, I looked at the rig and was thinking. I was even thinking of moving my main rig monitor to the new rig and see what it did. I'd already tried a different card so didn't see any need in repeating that. Then I had a thought. Why is it saying port DP-3? Why is it not port DP-0? I thought the first port was the one on the bottom. Turns out, the top port is the first one. So, I moved the cable to the first port, DP-0. I booted the rig up, started DM, got the login screen as usual and guess what was next, a complete desktop. I changed it to not power off or switch to a screensaver so that it would stay on and I could keep a eye on it. I heated up supper, ate, typing this reply and it is still running, in 1080P no less. Now tell me this, why would it not work on DP-3 or DP-2 when I tried those earlier on? Does one always have to have a monitor connected to DP-0 first then others as monitors are added? Now comes the next question. To move just KDE stuff over, desktop settings and such. ~/.local and .config. Are those the big ones? Also, I have a .kde4 directory, that's no longer used right? I think it died ages ago. I forgot all about that thing. I'll copy the other stuff over at some point but just want to play with the big stuff at the moment. In your list, #1 would have been the fix. It also turns out, it was me. I plugged the cable in the wrong port. No idea why everything else worked fine tho. All the boot media worked just fine. This is a large thread over something so simple. ;-) Thanks so much for all the help. The main rig is still sitting there at 1080P waiting on me. Finally, after over $1,000 spent, days of installing, twice, and a lot of testing, a working computer. :-D :-D Dale :-) :-)
