Dear all. According to chapter 18 of the Linux keyboard and
console HOWTO by Andries Brouwer there's no way to keep the
scrollback information after switching consoles:

"Upon changing virtual consoles, the screen content of the
old VT is copied to kernel memory, and the screen content of
the new VT is copied from kernel memory to video memory. Only
the visible screen is copied, not all of video memory, so
switching consoles means losing the scrollback information."

So, I contacted Andries and got the answer that a patch for
the Linux Kernel is needed. Is there any patch for such feature
being maintained? I'd like to save the last 1000 lines of
information on each tty (like in XTerm with saveLines using the
X Window System). And is such feature going to be included in
the 2.4 or any other branch? If not, why, since I doubt I'm the
first asking for this. I'm still using 2.2.9. In the meantime
I'm using GNU screen.

Thanks in advance.
