ETA: This is the original MWE in LyX How to change margin of the document title?
and I have the exact same question, for LyX, just for KOMA article class instead of the standard article class. Unfortunately I can't switch to the standard class instead and I have been unable to figure out on my own how to adapt the code from the answer to KOMA article. Any help would be much appreciated!
LaTeX MWE
\documentclass{scrartcl}
\title{This is a fairly long title for the document which should start at the top of the page}
\begin{document}
\maketitle
\end{document}

\coverpagetopmarginin the KOMA documentation? – henryflower Apr 21 '23 at 10:55\coverpagetopmarginis supposed to be adjustable by\renewcommand, so, e.g.\renewcommand{\coverpagetopmargin}{yourdesiredlength}. However, without a minimal example from you it is difficult to demonstrate or test. – henryflower Apr 22 '23 at 07:44titlepage=false, which is default withscrartcl) or a title page (optiontitlepage=true). And maybe is also depend on other information. So please add a minimal working example starting with\documentclassincluding\begin{document}and ending with\end{document}. The example should also include eventually used packages relevant for the title and all commands to reproduce your title problem. – cabohah Apr 24 '23 at 06:47Regarding the MWE, as the tags say, I am working with LyX, which has a different syntax than regular LaTeX. The reason why I didn't provide an MWE is because I have linked the question with the precise MWE applying to my situation first thing in my post - except that I, as stated, am using KOMA instead of the regular article class.
Because of the different syntax, to generate a LaTeX MWE, I would have to export the LyX document to LaTeX, then import it back, which kind of defies the point of using LyX.
– Neridi Apr 24 '23 at 08:51\renewcommand{\coverpagetopmargin}{yourdesiredlength}doesn't work because it also requires you to calltitlepage=firstiscover, which is however explicitly not what I am looking for, as I want the title to be on the same page as the rest of the text, as dictated by the article layout. – Neridi Apr 24 '23 at 10:21
