I use 120x80 xterms under X11 (which I start via
xterm -geometry 120x80). I also use some constantly running GNU screen sessions on a couple of different hosts -- both local to the mac and on some remote Linux boxes.
With Leopard, when I re-connected to an existing screen session, screen would suss out the size of the xterm it was running in and automatically expand to fill it.
With Snow Leopard, this no longer happens. Re-connecting to a running screen results in it coming up in 80x25. I have to resize the xterm window to get the screen session to expand out. Once I've done that once, I can disconnect and reconnect and screen does the right thing.
Is there any way to fix this and go back to the old xterm behavior?
(Snow Leopard does have a new version of xterm:
$ /usr/X11R6/bin/xterm -v XTerm(244)
Versus the version in Leopard:
$ /usr/X11R6/bin/xterm -v X.Org 188.8.131.523(241)
Haven't yet tried copying the Leopard xterm over to Snow Leopard...)
