I am *not* going to paste in almost 3,000 lines (what a *useful* logfile...

I know I can do it with NVidia, but this is just KDE's settings.Last I knew, you could 1) go into multi user mode (no x running) systemctl isolate multi-user #graphical is probably the default 2) Ask Xorg what it would do by default run 'Xorg --config > mynewxorg.conf.file' #this is IIRC without looking at man or Xorg --help #but I think you'll get the idea here. :) 3) go back to graphical systemctl isolate graphical hope this helps Even when this disclaimer is not here: I am not a contracting officer. I do not have authority to make or modify the terms of any contract.

Googling, I found Xorg :1 --configure, and it crashed every time, so I was wondering if I had to be in runlevel 3 for that to work. <snip> mark
