Description Sam Varshavchik 2007-03-02 04:15:11 UTC
Description of problem:

The interactive shell spawned by gnome-terminal inherits TERM=xterm.  This
appears to be hardcoded in the gnome-terminal binary.  It appears that the xterm
terminfo entry in FC6 (and possibly earlier) is not an accurate description of
gnome-terminal's terminal emulation.

The "gnome" terminfo entry appears to be a better fit for gnome-terminal. 
gnome-terminal should set TERM=gnome before spawning the login shell.

Version-Release number of selected component (if applicable):


How reproducible:

I can generally reproduce display corruption using cone (in Extras); but it
looks like you need to have a large folder hierarchy displayed.  By scrolling
up/down through the folder listing I can usually cause some minor visible

The corruption is gone if I set TERM=gnome.

By process of elimination, by comparing xterm and gnome terminfo entries, I
identified at least one code in xterm's terminfo entry that does not match
gnome-terminal's capabilities.  The terminfo entry for xterm contains this code:


If I remove the cbt code from the terminfo entry for xterm, and leave
TERM=xterm, the display corruption also disappears.  But there are also many
other differences between the two terminfo entries.  Other disrepancies are also

The current version of the ncurses package, used by cone and other
terminfo-based apps, aggressively tries to optimize its terminal output; it uses
nearly all terminfo entries where available, and is rather sensitive to
disrepancies between terminfo entries and the actual terminal device implementation.

Just another data point: I am using Scientific Linux 4, and I have screen
refresh troubles when running mutt in a gnome-terminal, which go away if I set
TERM=gnome.  The attachment is an email message which consistently triggers the
