I have seen this used in school situations with 3+ seats per PC.

that can add up when dealing with a dozen+ PCs.

For home use, not much a benefit, but I did have it setup years ago for the grandkids.

make proper backups before you try messing with partitions. Have windows reinstall media made ahead of time, just in case things go badly.

what you want to do is possible, but mistakes happen.

but they have an APK for the file manager ‘index’. so that’s what’s confused me.

I thought KDE was working on some cross platform programs, but I can’t recall the name of the project or the tools, they had a file manager, and a few other things. I thought it included a basic terminal emulator.

I may be thinking of the following project.

https://mauikit.org/apps/

it shows screen shots for ‘station’ on mobile, but I can’t find a .APK for it.

determine is the XFCE system is using sddm, lightdm, gdm3, there are other login managers as well, but those 3 are the most common.

you can then setup the same login manager kn the other system.

unless they are the same and it’s just a scaling issue due to the monitor resolution.

then I guess you could try the alternative login managers, and see if any look better.

for testing, and no, no issues at all with the various dot files.

Cluttered app menus, and an occasional “default open with app” setting changed is about the only issues.

I have 5+ DEs on my pop_os install, you don’t lose files in your users home.
