How to download and compile mutt from source in Debian

apt-get source mutt
    - nebo stáhnout

apt-get build-dep mutt
    - nainstaluje balíčky podle závislostí,
      aby šlo instalovat source balík mutt

    - kdyby to nešlo (chyba "Build-dependencies for rpm could not be satisfied"):
        - přidat za příkaz: -o Debug::pkgProblemResolver=true

configure-optiony se dávají do debian/rules

dpkg-buildpackage -rfakeroot -us -uc

(dělal jsem to pod rootem, nevím, proč mi druhý pokus selhal - možná jsem neaplikoval patch, už ani nevím, kde se to provádí - z rozbaleného tar.gz se druhý pokus nepovedl)

* kam som dal prepínač --with:
   do debian/rules

    * v gdb:
        v debian/:
        echo decstation-ultrix >target

Dell Latitude volume keys under Debian

Dell laptops have volume keys above the F-keys. This post explains how to enable them to control the volume.

First, the keys need to be recognized. One can set the right keyboard model in /etc/default/console-setup:
XKBMODEL="latitude"
Other options can be set also, e.g.:
XKBLAYOUT="us,cz"
XKBVARIANT=",qwerty"
XKBOPTIONS="lv3:ralt_switch,grp:alt_shift_toggle,grp:rwin_switch,grp:menu_toggle,grp_led:scroll"
That ensures that keys are mapped to names like "XF86AudioMute". Names can be used in the menu file, where you put commands for alsamixer to rise/lower the volume. Your menu file could be named .menu/volume-keys (explained in "Debian menu system"):
?package(alsa): needs="X11" section="Apps/Sound/Xmms commands" \
        title="Master mute" \
        shortcut="XF86AudioMute" \
        longtitle="X MultiMedia System" \
        command="amixer set Master toggle"
?package(alsa): needs="X11" section="Apps/Sound/Xmms commands" \
        title="Master up" \
        shortcut="XF86AudioRaiseVolume" \
        longtitle="X MultiMedia System" \
        command="amixer set Master 5%+"
?package(alsa): needs="X11" section="Apps/Sound/Xmms commands" \
        title="Master down" \
        shortcut="XF86AudioLowerVolume" \
        longtitle="X MultiMedia System" \
        command="amixer set Master 5%-"
Run update-menus and refresh your window manager. Finished.

By choosing the right keyboard model, following lines are applied, which should already be present somewhere in /usr/share/X11/xkb/symbols:
    key    { [ XF86AudioMute         ] };
    key    { [ XF86AudioLowerVolume  ] };
    key    { [ XF86AudioRaiseVolume  ] };
