I resolved the issue by placing the following xorg.conf file in
- the "Monitor" section makes 1368x768 available in the KDE
settings" --> "Display and Monitor"
- The "Screen" section scales my login screen
Modeline "1368x768_60.00" 85.25 1368 1440 1576 1784 768 771
781 798 -hsync +vsync
Option "PreferredMode" "1368x768_60.00"
Identifier "Default Screen"
# Modes "960x720"
Now that you've found a solution, I wonder why your particular choice. I'd
expect half of 2560 by half of 1440, 1280x720, to work a bit better than the
odd divisor that produces 1368x768.
1368x768 itself is odd. Many lower density screens use 1366x768 or 1360x768.
1368x768 is not one I've ever run across.
As long as you're not using a native mode anyway, you might want to see how
1600x900 works out.
Did you try without specifying a modeline? Last time I found Xorg couldn't
figure out the right modeline on its own was before Xorg, using XFree86. Thus
instead of 'Option "PreferredMode" "1368x768_60.00"' simply
Option "PreferredMode" "1368x768"
and omit the Modes line from the Display subsection, but to the monitor
adapting the actual numbers to whatever specs are provided for your Carbon's
display. Xorg is perfectly capable of automatically doing the same thing as gtf

Did you not try this first? At all?
