Hi,

You need to change the resolution within grub, which is advised if you have a 4k screen for example. (grub is also very slow on 4k screens)

in /etc/default/grub file, and add/replace the following line=

GRUB_GFXMODE=1280x1024x32,auto

Then run “update-grub” to update the GRUB.
This will run GRUB in 1280x1024x32 resolution, which is the workaround for this problem.
Please make sure the resolutiion is supported. The “auto” means that GRUB will fallback to auto detect in case the resolution isn’t supported.

(In reply to Bart from comment #1)

Thank you. Changing that line does solve the problem. Just realized I'm barking up the wrong tree though, I'm after automating this on system installation.

Thank you for your bug report! 
However this bug report was created/provided previous to 01/01/2023 and also has not received any updates since  before 01/01/2025. 
Unfortunately KDE neon no longer provides updates for anything older than noble 24.04 based edition's.
Please upgrade to KDE neon noble and if you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report.
Thanks for understanding!
