I try to make some very special setup works in 15.3 (it works in 15.1 in kde and in 15.3 with xfce), with kde.
to check what is done, I would like to where this setup is stored by the kde control center / display module, given it's only in kde that it don't works
any hint? in .local or .config I didn't find it, but I'm not sure of what to look for :-(
First, go into "System Settings" -> "Startup and Shutdown" -> "Background Services" and deselect "KScreen2" Next, log out of Plasma, login to some other session, navigate to ~/.local/share/, and delete any directory you find with the string kscreen in the name. Next, remove also ~/.cache/*. Once these are done, you can reopen a Plasma session and expect it will not mess with your display configuration.
the xrandr corresponding line is
xrandr --fb 1920x1080_60.00 --dpi 96 --output eDP1 --pos 0x0 --scale-from 1920x1080 --same-as VIRTUAL1
I wish I could understand what this is supposed to accomplish. Is your screen's native resolution 1280x720 or 1366x768? -- Evolution as taught in public schools is, like religion, based on faith, not based on science. Team OS/2 ** Reg. Linux User #211409 ** a11y rocks! Felix Miata
