From: Michael Schutte <michi@uiae.at> To: kbd@lists.altlinux.org Subject: [kbd] New vt_mode tool for kbd? Date: Mon, 21 Mar 2011 22:42:36 +0100 Message-ID: <20110321214236.GA13370@graeme> (raw) [-- Attachment #1.1: Type: text/plain, Size: 858 bytes --] Hi Alexey, The console-setup package in Debian needs a way to check for the text/graphics mode of the active VT (from a shell script). This can be done with “setfont -v -o /dev/null”, for example, but that isn’t very elegant. Julien Cristau has proposed a small utility (which I’m calling “vt_mode” for now) to report this information in a canonical fashion. I’ve adapted it to kbd; see attachment. Do you think this code is suitable for inclusion? If so, I am going to integrate it into the build system and write a short man page for it, so I can send you a proper patch. I’d like to hear your opinion!
