Description

This package contains dotfile-like configuration settings for Linux GUI programs. It is intended to be installed on MDVL systems but may not be suitable for general-purpose Debian installations given that some changes deviate far from the defaults and do not integrate well unless many other MDVL packages are also installed.

Configured Programs

Here is an overview on the files provided and the programs configured.

GTK-Configuration

The following files configure GTK (2.0 and 3.0) to use a dark theme and set GUI fonts to Terminus:

  • /etc/gtk-2.0/gtkrc
  • /etc/gtk-3.0/settings.ini
  • /usr/share/themes/masysma/gtk-2.0/gtkrc

Feh Keybindings

File /etc/feh/keys reconfigures the keybindings of the feh image viewer to be similar to plan_view.py. See also: image_viewer(32).

i3-Configuration

File /etc/i3/config configures the i3 window manager to use the [WINDOWS] (aka. [SUPER]) together with certain keys to manage windows. It is mostly based on an old i3 version's defaults with notable changes being described in the following:

bindsym $m+Shift+h        move left
bindsym $m+Shift+j        move down
bindsym $m+Shift+k        move up
bindsym $m+Shift+l        move right

All movement commands are configured to use VIM-style [H]/[J]/[K]/[L] keys:

bindsym $m+Escape         mode "passthrough"
mode "passthrough" {
	bindsym $m+Escape mode "default"
}

A passthrough mode is provided to be invoked by [WINDOWS]-[ESC] which disables all keybindings. This may be useful when interacting with Windows VMs and such.

bindsym Mod1+F1           exec /usr/bin/materm
bindsym Mod1+F2           exec /usr/bin/dmenu_run
bindsym Mod1+F3           exec /usr/bin/materm -e vifm /data/main
bindsym Mod1+F5           exec /usr/bin/materm -e d5mantui
bindsym Mod1+F7           exec GTK_THEME=Adwaita:dark /usr/bin/firefox
bindsym Mod1+F9           exec /usr/bin/materm -e htop
bindsym Mod1+F10          exec /usr/bin/virt-manager
bindsym $m+Shift+Delete   exec /usr/bin/q

Various programs are configured to be assigned to [ALT]-[FX] combinations where X is one of the F-keys' numbers like X=1 for [ALT]-[F1] to invoke a materm. The settings used here are expected to be changed by users to their respectively used applications. The defaults provided here are used as a reference across multiple Ma_Sys.ma systems. E. g. Ma_Zentral DVDs assign F1, F2, F7, F9 to Windows programs that perform similar tasks to their Linux counterparts configured here.

# requires xdotool, .mdvl/scrroot.txt, maim
bindsym --release Print   exec "/bin/sh -ec 'dnam=\\"$(cat \\"$HOME/.mdvl/scrroot.txt\\")/$(date +%Y%m%d)\\"; [ -d \\"$dnam\\" ] || mkdir \\"$dnam\\"; fnam=\\"$(date +%Y%m%d%H%M%S).png\\"; maim -i $(xdotool getactivewindow) > \\"$dnam/$fnam\\"'"

An elaborated screenshot function is assigned to the [PRINTSCREEN] key. This setting invokes the maim tool to take a screenshot of the currently active window and saves it into the directory path specified in $HOME/.mdvl/scrroot.txt. It automatically ensures that screenshots are stored into different subdirectories depending on the current day.

exec /bin/run-parts --exit-on-error --regex=".*" --verbose /usr/lib/mdvl-gui.d

This line enables the scripts from below /usr/lib/mdvl-gui.d to be automatically invoked upon GUI startup.

font -*-terminus-medium-*-normal-*-16-*-*-*-*-*-iso10646-1

# class                  border   bg       fg       split
client.focused           #cc4040  #cc4040  #ffffff  #ff0000
client.focused_inactive  #806060  #806060  #aaaaaa  #bb0000
client.unfocused         #201818  #201818  #505050  #400000
client.urgent            #ffaa00  #ffaa00  #ffffff  #ffaa00

bar {
	font -*-terminus-medium-*-normal-*-12-*-*-*-*-*-iso10646-1
	status_command /usr/bin/mai3bar --json
	position top
	tray_output primary
	colors {
		#                   border  bg      fg
		focused_workspace   #cc4040 #cc4040 #ffffff
		active_workspace    #806060 #806060 #aaaaaa
		inactive_workspace  #201818 #201818 #505050
		urgent_workspace    #ffaa00 #ffaa00 #ffffff
		background                  #000000
		statusline                          #ffffff
		separator                           #333333
	}
}

This block configures a Ma_Sys.ma-specific color scheme that is based on red colors. Additionally, the i3bar is populated by mai3bar -- see i3bar(32). Additionally, the GUI is configured to use Terminus for all window manager parts.

GUI Autorun Scripts

Directory /usr/lib/mdvl-gui.d is checked for scripts to automatically invoke upon starting i3 with the configuration described above. Relevant default configuration is found in file 00-initial.sh:

# -- Keyboard --
/usr/bin/xmodmap
setxkbmap -layout de -variant deadgraveacute
# Speed up key repeat
xset r rate 270 30
# disable bell
xset b 0

# -- Theme for password-gorilla --
if [ -d /usr/share/tcltk/awthemes ]; then
	echo "*TkTheme: awdark" | xrdb -merge
fi

# -- Background Processes --
/usr/bin/screenindex -l -g &

if [ "$(head -c 3 /etc/hostname)" = "vm-" ]; then
	/usr/bin/spice-vdagent &
	xrandr --dpi 109
else
	/usr/bin/xscreensaver -no-splash &
fi

The keyboard configuration is set to German keyboard layout, faster repeat rate and all bell sounds are disabled. For details on the effects of the keyboard configuration, see also: linux_x11_keyboard_configuration(37).

Afterwards, some optional components are invoked depending on whether they are present:

  • If installed, theme awdark is set for use with Tk GUIs like password-gorilla. This theme is available from Debian 11 onwards.
  • If installed, screenindex logging is started in background. See screenindex(32) for details.
  • Finally, depending on whether the current system is a virtual machine (decided by the name for the lack of a better criterion), different processes are started: Physical systems run xscreensaver whereas virtual machines start spice-vdagent if installed and fix the DPI setting that is sometimes incorrect in VMs.

The advantage of the run-parts-based approach here is that system-specific additional GUI startup scripts (like e.g. nm-applet for laptops) can be provided by separate packages.

Changes to /etc/skel

In the past, most Ma_Sys.ma dotfiles were configured in /etc/skel -- a directory that is taken as a base for creating new users. Given that this makes updates slow (new settings are only applied upon re-creating the user!), this approach is newly avoided whenever possible.

Currently, the following files are provided for /etc/skel:

.xscreensaver : Default configuration for xscreensaver .xsession : Default X11 session set to i3
