====== Xorg Tips ==
===== X-server Configuration, default way ==

According to [[slack>slackware-13.0/CHANGES_AND_HINTS.TXT]] as of Slack 13.0 an xorg.conf is not necessary any more. But mouse and keyboard might still need customization:

==== Keyboard ==
=== Slack 13.37 ==

To set e.g. a German keyboard layout copy ''/usr/share/X11/xorg.conf.d/90-keyboard-layout.conf'' to ''/etc/X11/xorg.conf.d/90-keyboard-layout.conf'' and edit the line

  Option "XkbLayout" "us"
to
  Option "XkbLayout" "de"

<note tip>This can be done with the script [[http://think-deep.com/becki/sources/my_slack_settings|my_slack_settings]].</note>

=== Slack 13.0 - 13.1 ==

To set e.g. a German keyboard layout copy ''/usr/share/hal/fdi/policy/10osvendor/10-keymap.fdi'' to ''/etc/hal/fdi/policy/'' and edit the line

  <merge key="input.xkb.layout" type="string">us</merge>

to

  <merge key="input.xkb.layout" type="string">de</merge>

From [[slack>slackware-13.0/CHANGES_AND_HINTS.TXT]].

==== Touchpad ==
=== Slack 13.37 ==

Scrolling works out of the box. Just use 2 fingers instead of one finger on left side.

==== Touchpad and USB-Mouse with wheel at the same Time ==

<note important>Only necessary for Slack 13.1 and below</note>

To enable vertical scrolling when dragging along the right edge uncomment the line, copy ''/usr/share/hal/fdi/policy/10osvendor/11-x11-synaptics.fdi'' to ''/etc/hal/fdi/policy/'' and uncomment the line:

  <merge key="input.x11_options.VertEdgeScroll" type="string">true</merge>

FIXME How to enable "taps" for emulating the left mouse key?

===== X-server Configuration, old way ==

You might still need an ''/etc/X11/xorg.conf'' even with Slack 13.0 and above e.g. if you want to use a [[nvidia_driver_setup|binary only graphics card driver]]. You can create a basic ''xorg.conf'' with ''xorgsetup'' (Or ''X -configure'' if you don't have Slackware) See [[slack>slackware-13.1/CHANGES_AND_HINTS.TXT]]

''xorg.conf'' & ''xorg.conf.vesa'' are initially the same (Slack10.2 - Slack12.2). Copy xorg.conf to xorg.conf.org to indicate that the pristine file is still present (usfull for automated later upgrades with [[diffupgrade]])

Note: With Slack 12.2, a built in graphic card from Intel and a 1280x1024 LCD monitor, the command ''xorgsetup'' (see [[slack>slackware-12.2/Slackware-HOWTO]] did a great job. Everything (keyboard, mouse, card) worked out of the box. (Just adding DPMS was necessary (see below).) So try this first!

==== Overall File Structure ==

<code>
xorg.conf
|
|-- Module
|
|-- Files
|
|-- Server Flags
|
|   /-- InputDevice kbd (Keyboard)
|   |
|   |-- InputDevice mouse
|   |
|   |   /-- Monitor
|   |   |
|   |   |-- Device (graphics card)
|   |   |
|   |-- Screen
|   |
`-- ServerLayout
</code>

==== Keyboard ==
<code bash>
#Option "XkbModel"      "pc105"       # activates the '<|>' Key
                                      # not necessary anymore since slack12.2
Option "XkbLayout"	"de"          # activates the Umlauts
Option "XkbVariant"	"nodeadkeys"
</code>

Note: In case of doubt you can try and find out the necessary configuration settings for xorg.conf with KdeControlCenter-> Regional&Acessibility-> KeybordLayout. These settings overwrite the settings of xorg.conf

==== Mouse ==
=== Symlink /dev/mouse ==

(-> ''/dev/psaux'' for PS2-mice und notebooks - not valid any more for Slack12.0 and above, here the default always seems to be ''/dev/input/mice'' regardless if it is an PS2 or USB mouse)

-> ''/dev/input/mice'' for USB-mice. Source: delete /dev/mouse start X, then a dialog appears, where USB-mice can be selected and the proper symlink will be created --- fritz / Slack10.2 / 2006-07-31

Check symlink with ''cat /dev/mouse''  --- 2006-08-02

=== Activate Mouse Wheel ==

<code bash>Option "ZAxisMapping" "4 5"</code>

Dieser Eintrag kam von kxconfig (ilse / slack 9.0) und mappt die Z-Achse (=Mausrad) auf die virtuellen Tasten 4 & 5; 
ohne diesen funzt das Mausrad nicht. Siehe auch /usr/X11/lib/X11/doc/README.mouse

Not necessary as of Slack 12.0 any more:

<code bash>Option "Protocol" "IMPS/2"</code>

See "The darn scroll wheel in 10.2" auf [[http://groups.google.de/group/alt.os.linux.slackware]]  --- fritz / Slack10.2 / 2006-08-02

=== Generic PS2 Mouse ==

<code bash>
Option  "Protocol"      "Auto" # Not PS/2, otherwise middle Button/Wheel doesn't work!
Option  "Device"        "/dev/mouse"
Option  "ZAxisMapping"  "4 5"
</code>

=== Touchpad and USB-Mouse with wheel at the same Time ==
== Since Slack 12 ==

Verify symlink: /dev/mouse -> /dev/input/mice

<code bash>
# file: /etc/X11/xorg.conf
...
Section "InputDevice"
    Identifier  "Mouse1"
    Driver      "mouse"
    Option      "Protocol"     "Auto"
    Option      "Device"       "/dev/mouse"
    Option      "ZAxisMapping" "4 5"
EndSection

</code>

== Below  Slack12 ==

<code bash>
# file: /etc/X11/xorg.conf
...
Section "InputDevice"
    Identifier  "myTouchpad"
    Driver      "mouse"
    Option      "Protocol"     "PS/2"
    Option      "Device"       "/dev/psaux"
EndSection

Section "InputDevice"
    Identifier	"myUSBMouse"
    Driver	"mouse"
    Option      "Protocol"     "IMPS/2"
    Option      "Device"       "/dev/input/mice"
    Option      "ZAxisMapping" "4 5"
EndSection
...
Section "ServerLayout"
    ...
    InputDevice "myTouchpad"   "CorePointer"
    InputDevice "myUSBMouse"   "SendCoreEvents"
    InputDevice "Keyboard1"    "CoreKeyboard"
EndSection
</code>

==== Monitor ==

Since Slack 12.0 I just keep the defaults from the original xorg.conf

==== Device (graphics card) ==

Selectin the right driver my have an impact on the look of the fonts in KDE (Slack10.2 / fritz) and xine, which my lose too much frame with the vesa driver only.

''lspci -v'' helps to identify the card type. Then get the appropriate driver name with ''xorgconfig'' and edit xorg.conf manually. 

Note: Sometimes xorgconfig does not help. Eg on a Compaq 6710b Notebook you have an intel card. But the type or driver is not listed in xorgconfig. In this case search the internet with eg "compaq 6710b 1280x800 notebook xorg.conf" and you may find [[http://gentoo-wiki.com/HARDWARE_HP_Compaq_6710b|help]] which states that the driver is 'intel'. Also peeking at the autogenerated xorg.conf of a live-CD like Slax may help to get the right settings.

Examples:
<code bash>
Section "Device"
    Identifier  "myaticard"
    Driver      "ati"
EndSection
</code>

<code bash>
Section "Device"
    Identifier  "myintelcard"
    Driver      "intel"
EndSection
</code>

==== Screen ==
=== DPMS ==

Add 
<code bash>Option "DPMS"</code>
to the screen section. This enables display power management. (Source: [[tldp>HOWTO/Battery-Powered/|Battery-Powered Howto]]) This enty is also possible in section monitor as a "per monitor" option.

If you want to modify the default values for standby, suspend and off-time, you have to set ''StandbyTime'', ''SuspemdTime'' and ''OffTime'' in section ''ServerFlags'', see ''man xorg.conf'' for the default values and more info. 

=== Widescreen Notebooks ==

You have to know the native resolution of the notebook eighter from the data sheet, or a live CD like Slack. Then add the resolution as the first mode. The example shows the settings for a Compaq 6710b:

<code bash>
Section "Screen"
    ...
    Subsection "Display"
        Depth 24
        Modes "1280x800" "1024x768" ...
    EndSubsection
    ...
EndSection
</code>

==== Open / Todo ==

  * Direct Rendering Interface for xscreensaver? See master11.slack.hist
  * Don't omit DGA extension for xawtv, See ilse.hist

===== Nvidia driver setup ==

Nvidia cards work better with their propiretary driver. See [[Nvidia driver setup]] to check if this is necessary and how it is done.

===== Schriften / Fonts ==
==== Howto ====

Schriften werden einfach vom Netz runtergeladen entpackt und in eines der Verzeichnisse gelegt, die in /etc/fonts/fonts.conf aufgeführt sind. Es empfiehlt sich für jede neue Schrift / Schriftpaket ein eigenes Unterverzeichnis anzulegen.

Siehe auch http://eyegene.ophthy.med.umich.edu/unicode/#fontinst (gefunden bei Inkscape in einem durch Zufallsscript ausgewähltem Beispielbild für Unicode). Hilfreich auch http://ldp.bootet.net/HOWTO/Font-HOWTO/ und evt man fonts-conf

/etc/fonts/fonts.conf gehört wie /etc/X11/xorg.conf auch zum X11-Paket. Jedoch bisher keine Ahnung wie die Font-Einträge in xorg.conf mit denen von fonts.conf in Verbindung stehen.  --- [[becki@web.de|becki]] 2006-08-22 22:30

==== Schriftpakete  ====
  * [[http://www.thibault.org/fonts/|John Stracke's Fonts]] über unifont.org -> Scientific, Scholarly, Artistic
  * [[http://freshmeat.net/projects/msfonts/|msfonts]] gefunden direkt bei Freshmeat

==== Speziell Aterm / Xterm ====

Schriftart (und damit auch Größe) kann man angeben als Schalter mit ''-fn'' oder in ~/.Xdefaults zB in der Zeile ''Aterm*font:''
Als Wert kann dabei jeweils ein Angabe in der Form wie zB ''9x18'' oder  ''-misc-fixed-medium-r-normal-*-15-*-*-*-*-*-iso8859-15'' stehen

Quelle Kurzform: man aterm und ''locate 7x14'' ergibt die Fonts in /usr/X11/lib/X11/fonts/misc/ als einzige Möglichkeit.
Quelle Langform: Vorlage aus Konfigbeispielen von Fluxbox und durch Rumprobieren mit xfontsel

FIXME Mal bei Fluxbox nachgucken, wie die Artwitz-Fonts in aterm konfiguriert werden

==== Drucken ====

Bei Kword und Abiword (Stand Slack 10.1; Rechner berta; Drucker Canon S500; 2006-10-08) muß beim Druckbefehl auf jeden Fall "Schriften einbinden" bzw. "Schriften einbetten" angehakt werden, sonst entstehen bei Abiword Lücken nach Umlauten und bei Kword werden keinerlei Serifen verwendet. Das aktikvieren bewirkt, daß die Fonts mit zum Drucker geschickt & nicht die Druckereigenen Schriften verwendet werden. Quelle: Hilfe von Abiword

==== Antialiasing ====

Kantenglättung muß bei Kde unter Kontrollzentrum > Erscheinungsbild > Schriften aktiviert werden, sonst sieht alles beschissen aus. Bei fluxbox scheint das defaultmäßig aktiviert zu sein

===== Displaymanager ======
==== startx ==

''startx'' is not a displaymanager, but it can also start an X-Session, when no displaymanager is running, typically in runlevel 3.

  * ''xwmconfig'' called by root creates ''/etc/X11/xinit/xinitrc''. See ''man xwmconfig''
  * ''xwmconfig'' called by non-root user creates ''$HOME/.xinitrc''.
  * ''startx'' calls ''$HOME/.xinitrc'' if it is present (runnable or not), otherwise ''/etc/X11/xinit/xinitrc'' is called.

==== Kdm ==
=== Background Infos ==

Ermittelt auf Slack 10.2  --- 2006-02-15 11:32
Infoquelle: KDE-Hilfezentrum -> Kontrollzentrum-Module -> Anmeldungsmanager
config-dir: cfgdir=/etc/kde/kdm
Konfig-Datei: $cfgdir/kdmrc

  * After login, kdm calls $cfgdir/Xsession and passes the windowmanger-command e.g. ''startfluxbox'' in ''$1'' (tested with ''logger'')
  * ''$cfgdir/Xsession'' calls ''/etc/xprofile'' (user-independed autostart ?)
  * ''$cfgdir/Xsession'' calls ''$HOME/.xprofile'' (user-depended autostart ?)
  * If the windowmanger-command is 
    * ''custom'', then ''$cfgdir/Xsession'' calls ''$HOME/.xsession'' (must be runnable)
    * ''default'' , then ''$cfgdir/Xsession'' calls ''startkde''
    * Something else, then ''$cfgdir/Xsession'' calls the windowmanger-command
  * Der WM-Befehl und WM-Name in Xsession kommt aus /opt/kde/share/apps/kdm/sessions/[wm].desktop (getestet)
  * Die Liste der zur Auswahl stehenden WM's wird automatisch generiert aus der Schnittmenge der Exec-Einträge in den .desktop-Dateien und der vorhandenen gesamtmenge Befehlen, gesetzt durch $PATH. Siehe [[http://docs.kde.org/stable/en/kdebase-workspace/kdm/different-window-managers-with-kdm.html|kdm Handbook]]

=== Remote Login ==

--- Slack11.0 2006-11-04 09:13

== AppServer Side ==

Enable Xsmcp in /opt/kde/share/config/kdm/kdmrc
<code bash>
[Xdmcp]
Enable=true
</code>
FIXME How to restrict acces to only certain terminal hosts?

== Terminal Side ==

Substiute /etc/rc.d/rc.4 with:
<code bash>
while true; do
    echo "Starting up X11 session manager..."
    /usr/X11/bin/X -query hostnameOfAppServer
done
</code>

=== GUI Configuration ==

As of KDE4 the KDM configuration dialog is hard to find. Start it with ''kdesu kcmshell4 kdm'' from a terminal! Found this with ''Alt + F2'' -> rype ''kdm'' -> Select appropriate proposal (logged into KDE4 as normal user)

==== WM-independent Autostart ==

  * Create ''$HOME/.xprofile'' wich calls all apps you want to have started automatically, eg:
<code bash>
#!/bin/bash
numlockx on
xscreensaver -no-splash &
mrxvt -ip 0,1,2 &
gkrellm --withdrawn &
firefox &
thunderbird &
jedit &
kmix &
</code>

  * Call ''xwmconfig'' as standard user and select your favorite windowmanager, eg fluxbox. This generates ''$HOME/.xinitrc''.
  * Insert the line "''. .xprofile''" in ''$HOME/.xinitrc'' just bevor the last line which starts the WM:
<code bash>
#...
. .xprofile # <== insert this line
# Start the window manager:
exec /usr/bin/startfluxbox
</code>

  * Optionally create ''$HOME/.xsession'', make in runnable and call your favorite windowmanager ther as well:
<code bash>
exec /usr/bin/startfluxbox
</code>

This will always start your autostart apps either after calling ''startx'' (in runlevel 3) or after login in KDM, GDM or XDM (in runlevel 4) , regardless which WM you selected.

Note that you you have to unselect KDE Control Center -> KDE Components -> Session Manager -> On Login -> Restore previous session if you use KDE, otherwise more and more autostart apps would be startd on every login!

==== GDM, XDM ==

Stand: Slack 10.0
Einzige Info zu gdm gibts nur mit der Gnome-Hilfe /usr/bin/gnome-help -> yelp
Info zu xdm: man xdm
gdmconfig ist eine Gui zum Konfigurieren von /etc/X11/gdm/gdm.conf

xdm startet /etc/X11/xdm/Xsession ohne Argumente (verifizieren!), dieses versucht daraufhin ~/.xsession auszuführen, & wenns das nicht gibt /etc/X11/xinit/xinitrc (so wie bei startx)

gdm sucht u.a in /etc/X11/sessions/ & /etc/X11/dm/Sessions/ (letzteres veraltet, kann in gdm.conf mit SessionDesktopDir geändert werden) nach <windowmanger>.desktop Dateien (z.B fluxbox.desktop).
Diese sind im Anmeldebildschirm auswählbar. Sie enthalten alle einen Pfad zum zu starteten script, dies ist bei allen "/etc/X11/xdm/Xsession <windowmanager>"

gdm führt jedoch nicht /etc/X11/xdm/Xsession sondern immer /etc/X11/gdm/Xsession aus & übergibt and dieses "/etc/X11/xdm/Xsession <windowmanager>" (bzw "/etc/X11/xdm/Xsession default" wenn "voreingestellte Systemsitzung" ausgewählt wurde)
xdm/Xsession & gdm/Xsession sind fast gleich, nur das PV bei gdm/Xsession das zusätzlich im 1.Argument enthaltene /etc/X11/xdm/Xsession wieder rausfiltert & nur <windowmanger> drinläßt
Findet Xsession den jeweils ausgewählten <windowmanger>, so wird er mit z.B "exec fluxbox" gestartet.

Dies alles ausprobiert über die erstellte Datei /etc/xprofile & logger. Diese wird von xdm/Xsession & gdm/Xsession gesourced & kann imho zum WM- und user-unabhängen autostart von Programmen verwendet werden.

===== Multimedia Keys ==
==== Map Keycodes to Keynames ==

Get the numerical keycodes of your multimedia key with command ''xev''. The decimal number behind the word 'keycode' in stdout is the keycode.

Map the keycodes with the appropiate xorg-events in the file ~/.Xmodmap per user or better in /etc/X11/xinit/.Xmodmap for all users. For a valid list of keynames look at /usr/X11R6/lib/X11/XKeysymDB

These files are passed to the xmodmap command in the scripts /etc/X11/xinit/xinitrc and ~/.xinitrc, i.e. when X is starting via ''startx''. /etc/X11/xinit/.Xmodmap is also applied when X isn't started with ''startx'' but with e.g. the fluxbox-entry in kdm or gdm (tested on fritz/Slack10.2).

My .Xmodmap file: (Another example can be found at http://www.xs4all.nl/~hanb/configs/dot-Xmodmap )
FIXME Put in my real Xmodmap!
<code>
! These are the for the multimedia keys on my keyboard.
keycode          161 = XF86Calculator
keycode          223 = XF86Sleep
keycode          174 = XF86AudioLowerVolume
keycode          176 = XF86AudioRaiseVolume
keycode          160 = XF86AudioMute
keycode          162 = XF86AudioPlay
keycode          164 = XF86AudioStop
keycode          144 = XF86AudioPrev
keycode          153 = XF86AudioNext
keycode          237 = XF86AudioMedia
</code>
