On upgrading to 16.04 from 15.10, my font size was tiny. Somewhere I found the suggestion to go to:
System Settings > Display and Monitor > Display Configuration > Scale Display
And change the scale setting. I did this (changed it to 3), it change the size of the GUI but not the font, and I eventually fixed the font size by setting the DPI in the
xorg.conf generated by
nvidia-settings. I would now like to undo the scale display setting. But I can't because now the GUI is so large that that part of the Display and Monitor window is off the screen. (In fact, I can only get to Display and Monitor by changing System Settings to the tree view, otherwise it's off the screen as well.) There is a scroll bar, but it won't scroll far enough.
I though I had found the file where this is stored in,
~/.config/startupconfig, which has the line:
However, when I change the 3 to a 1, it turns back to a 3 next time I restart KDE and the problem persists.
I tried running
systemsettings5 using ssh to display it on another computer, but it crashes as soon as I go into the Display and Monitor part.
Any idea of where this is stored or how I could reset it without losing all my other KDE settings?
