#! /bin/sh set -e # Based on setupcon, but stripped down for use in a udev rule. # We have to do several basic things here, each of which has specific state # requirements: # # 1) Set Unicode/non-Unicode mode on each virtual console. # # The terminal line emulation on the virtual console must not be in raw # mode (as in cfmakeraw). # # 2) Set the font and ACM on each virtual console. # # The virtual console must not be in KD_GRAPHICS mode. If using vgacon, # the *foreground* virtual console must not be in KD_GRAPHICS mode either # as then we'll corrupt video memory. # # 3) Set the keyboard mode on each virtual console to K_XLATE or K_UNICODE # as appropriate. # # The virtual console must not be in K_RAW or K_MEDIUMRAW mode. # # We don't have to set the console keymap here. This only needs to be done # once after setting the keyboard mode, so it belongs in an Upstart job # instead. export PATH="/bin:/sbin:$PATH" . /etc/default/console-setup # CODESET [ "$CODESET" != guess ] || CODESET='' if [ -z "$CODESET" ]; then case "$CHARMAP" in UTF-8) CODESET=Uni2;; ARMSCII-8) CODESET=Armenian ;; CP1251) CODESET=CyrSlav ;; CP1255) CODESET=Hebrew ;; CP1256) CODESET=Arabic ;; GEORGIAN-ACADEMY) CODESET=Georgian ;; GEORGIAN-PS) CODESET=Georgian ;; IBM1133) CODESET=Lao ;; ISIRI-3342) CODESET=Arabic ;; ISO-8859-1) CODESET=Lat15 ;; ISO-8859-2) CODESET=Lat2 ;; ISO-8859-3) CODESET=Lat38 ;; ISO-8859-4) CODESET=Lat7 ;; # sometimes Lat15 ISO-8859-5) CODESET=CyrSlav ;; ISO-8859-6) CODESET=Arabic ;; ISO-8859-7) CODESET=Greek ;; ISO-8859-8) CODESET=Hebrew ;; ISO-8859-9) CODESET=Lat15 ;; ISO-8859-10) CODESET=Lat15 ;; ISO-8859-11) CODESET=Thai ;; ISO-8859-13) CODESET=Lat7 ;; ISO-8859-14) CODESET=Lat38 ;; ISO-8859-15) CODESET=Lat15 ;; ISO-8859-16) CODESET=Lat2 ;; KOI8-R) CODESET=CyrKoi ;; KOI8-U) CODESET=CyrKoi ;; TIS-620) CODESET=Thai ;; VISCII) CODESET=Vietnamese ;; *) ;; esac fi # FONTSIZE if [ -z "$FONTSIZE" -o "$FONTSIZE" = guess ]; then FONTSIZE=16 fi case "$FONTSIZE" in 8x*) FONTSIZE=${FONTSIZE#*x} ;; *x8) FONTSIZE=${FONTSIZE%x*} ;; *x*) a=${FONTSIZE%x*} b=${FONTSIZE#*x} if [ "$a" -lt "$b" ]; then FONTSIZE=${b}x${a} fi ;; esac setup_unicode () { # Set up Unicode/non-Unicode mode. # TODO: this will probably break something if terminal line emulation is # in raw mode. if [ "$CHARMAP" = UTF-8 ] || [ -z "$ACM$CHARMAP" ]; then printf '\033%%G' >"$1" else printf '\033%%@' >"$1" fi } setup_font () { # Set the font and ACM. setfont will silently do nothing for a console # in graphics mode.
