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)](image_viewer.xhtml).



## 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)](i3bar.xhtml). 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`:



~~~{.bash}

# -- 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)](../37/linux_x11_keyboard_configuration.xhtml).



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)](screenindex.xhtml) 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`
