[Desktop-packages] [Bug 1770494] Re: Does not display VT-100 control codes correctly/consistently
What's the version of GNOME Terminal on CentOS that you're referring to, where you don't face these issues? GNOME Terminal (more precisely, the underlying VTE widget) was improved a lot during the last 4 years, tons of emulation (and other) bugs were fixed. The most relevant one is probably https://bugzilla.gnome.org/show_bug.cgi?id=732586. I can't reproduce the issues on Ubuntu 18.04 (gnome-terminal 3.28, vte 0.52). I personally recommend to you to upgrade to 18.04 soon (14.04 will EOL in a year anyway). It's pretty unlikely that these emulation fixes will be backported to 14.04. (My guess is that GNOME Terminal in Ubuntu 16.04 is most likely already fixed.) (Disclaimer: I'm a GNOME Terminal / VTE guy, but not an Ubuntu developer, so it's not Ubuntu's recommendation to you to upgrade.) > in Ubuntu Gnome terminal it is rendered as a cursor that is the color of a 50% blend between the background and foreground color, making it the best appearing terminal I've used Thanks; not everyone shares your opinion though, see https://bugzilla.gnome.org/show_bug.cgi?id=778122 :) ** Bug watch added: GNOME Bug Tracker #732586 https://bugzilla.gnome.org/show_bug.cgi?id=732586 ** Bug watch added: GNOME Bug Tracker #778122 https://bugzilla.gnome.org/show_bug.cgi?id=778122 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-terminal in Ubuntu. https://bugs.launchpad.net/bugs/1770494 Title: Does not display VT-100 control codes correctly/consistently Status in gnome-terminal package in Ubuntu: New Bug description: I'm writing a shell script that draws in color to any VT-100 terminal.
