Lately, I've noticed that text apps under xterm snap back to the
original screen after the app finishes. This doesn't happen with
all apps. When I hit "q" in "top", the output stays on the screen.
But other apps like "mtr" and "vim" and "less" restore the screen from
which they were launched, which is extremely annoying.
"mtr", "vim", and "less" all three use what Xterm calls the "Alternate
Screen". You can see this while the programs are running by looking at
the VT Options menu (Ctrl+Middle Click) and seeing that the "Show
Alternate Screen" is checked.
"top" on the otherhand does not use the "Alternate Screen".
There may be a way to disable the "Alternate Screen", but I don't know
for sure, muchless what it would be. I'd suggest Reading the ""Fine
Manpage. (Or at least searching said manpage.)
A long time ago I ran into this problem and was advised to add
"XTerm*titeInhibit: true" in .Xresources. It seems to have stopped
working recently. Last night on a web forum people were comparing
response times from 1.1.1.1 DNS server. I ran "mtr" in xterm but the
output would disapper entirely when I hit "q". I managed to freeze the
output with {CTRL}{S} so I could do a copy/paste into a post. But I'd
like a clean solution rather than a clunky workaround.
I would be shocked to learn that a title (bar?) related setting would
have anything to do with the "Alternate Screen". - If this worked, I'm
guessing that it did so by breaking something else that would trigger
the "Alternate Screen". (There's a 1000% chance that I'm wrong here.)
Please let us know what you find.
