Display resolution after install

[claydoh]

Thank you claydoh. I really appreciate the help you have been giving me. I'm about to leave on holiday for a couple of weeks. I would like to investigate your last option, can I resume on return?

Of course!

i have the same issues, when using live cd from USB, it can set to 1920x 1024 on my Lenovo Y50-70 notebook. after install Kubuntu 24.10. the resolution unable to change, it default using 3840x 2160;
only can use the scale to change the text size.
Previously it is installed kubuntu 23.04, the resolution is working as normal.

and this issues is not only happen in kubuntu, i have installed KDE neon / openSuse / mx Linux which the same notebook, every times have format the /boot/efi & / partition.
