Thank you Omer, there was no indication in the KDE dialogue that was
even necessary.
Going through the manpage, it looks like I need the --fb flag.
However, it seems to automatically calculate the size if none is
given:
--fb widthxheight
Reconfigures the screen to the specified size. All configured
monitors must fit within this size. When this option is not pro‐
vided, xrandr computes the smallest screen size that will hold
the set of configured outputs; this option provides a way to
override that behaviour.
In any case, the problem might be that my video driver doesn't support
such a large screen:
✈dcl:~$ xrandr --fb 3360x1050
xrandr: screen cannot be larger than 1680x1680 (desired size 3360x1050)
✈dcl:~$ xrandr --fb 1680x2100
xrandr: screen cannot be larger than 1680x1680 (desired size 1680x2100)
How can I check if this is a driver issue, short of installing a
different driver?
