Subject: Re: More than 256/512 glyphs on the Liinux console

Hello, dri-devel.

The context of the following post is a thread on Linux kernel lists where
I am proposing to extend the Linux console to handle more than 256/512
distinct glyphs.

Is this (still) the case?  Have people on dri-devel developed a Linux
console which supersedes the code in drivers/tty/vt, or are they in the
midst of doing so?

Where can I best inform myself about this, and (possibly) install this
replacement console on my system for my own use?

Thanks for any information!
