Description Maximilian Trummer 2017-11-09 16:59:10 UTC

wavemon 0.8.1-2.3 has broken output in the Konsole terminal program.

Workaround: Manually setting TERM=linux or TERM=xterm-color before sterting wavemon.

The bug doesn't appear on xterm or the native Linux framebuffer terminal.

Comment 1 Martin Pluskal 2017-11-24 08:37:05 UTC

I am pretty sure that this would be another ncurses bug

Comment 2 Martin Hauke 2017-11-24 20:57:17 UTC

I just installed a fresh and fully updated Tumbleweed VM with an KDE environment and can't reproduce this bug.
Without touching any configuration files the TERM variable is set to xterm-256color and wavemon does work as expected.
Can you please show the output from your TERM variable
$ echo $TERM

Konsole with "xterm-256color"

Comment 5 Maximilian Trummer 2017-11-24 21:13:07 UTC

Konsole and the framebuffer have problems with "xterm-256color".
xterm itself has no issues when setting TERM=xterm-256color

Comment 6 Maximilian Trummer 2017-12-06 19:42:15 UTC

The error affects 'atop' too by the way.
For some reason Konsole doesn't like xterm-256color.

Comment 7 Martin Hauke 2017-12-06 21:32:28 UTC

I can reproduce the error now.

Like Martin already said it is a bug in ncurses.
Subpackage terminfo-base seems to ship a broken version of /usr/share/terminfo/x/xterm-256color

See https://bugzilla.opensuse.org/show_bug.cgi?id=1054448 for more details.

Comment 8 Dr. Werner Fink 2017-12-07 09:28:23 UTC

Update ncurses to the *latest* version 6.0 with patch level 20171118 and also you might update to the latest konsole.

Beside this konsole is not an XTerm that is do not use "xterm-256color" if konsole does not fit the features of current "xterm-256color" which is not a bug of ncurses as TERM variables never reprogram terminals but only describe them.

Comment 9 Thomas Dickey 2017-12-23 18:49:30 UTC

The change would be here:

https://cgit.kde.org/konsole.git/tree/src/Vt102Emulation.cpp#n683

but konsole's developers have not made a change for this bug.

Comment 10 Wolfgang Bauer 2018-02-01 13:57:23 UTC

This definitely looks like it's caused by the missing REP support in konsole.
So let's mark it as duplicate again.

A fix is on the way:
https://build.opensuse.org/request/show/571654

Please reopen if there still is a problem after the next konsole update.
