The resolution is wrong in sddm and in plasma launched with startx
from a text terminal (Ctrl+Alt+F2).
I do not know what is vttys but the text shown in the terminal window
(Ctrl+Alt+F2) is fine.
Ctrl-Alt-F2 puts you on a vtty. Ctrl-Alt-F3, Ctrl-Alt-F4, etc. are same. You say
terminal window, but it's not a "window" when it's a full screen. Vtty
virtual terminal, or virtual tty (archaic teletype). My question was not about
whether text is "OK", but whether the framebuffer (vtty) mode producing text is
1024x768 as you're getting in SDDM, or 1920x1080 as you expect.
