Hello.
I have a need to learn to read and write Ukrainian and Korean concurrently.
I use Debian SID, but need to have three different language environments simultaneously running on the same machine.
One thought was to create two new users for the Ukrainian and Korean environments, using ctrl-alt-F2 with starx to new X-session for Uk., and ctrl-alt-F3 startx for third X-session for Ko, leaving the standard running X-session for my native En. stuff.
I'll have to figure out how to do this stuff.

Then one thought; could Knoppix be booted from within the running Debian system to use in either the Uk. or Ko. locale setup?

I have not seen any discussion of Knoppix use like this, so thought to inquire.
If this is not possible, perhaps a suggestion of a specialized version of Knoppix especially tweaked to allow multi-language learning and document translation environments to be switchable "on the Fly" would show a great need for such tool.
Thank you.
