Desktop, light setup

Revision as of 17:48, 22 August 2015

After installing and configuring the base system, here are instructions on how to get a light desktop up and running quickly. The instructions provided show how to get xdm, slim or wdm login managers working. This example on the window manager JWM provides insight on how to install other window managers.

Install

The following input is sufficient to install the programs for a running Desktop system:

% pkg install xorg jwm slim

Alternatively, ports may be installed. xdm and wdm login managers are other options.

Desktop login

Basic session managers are XDM, WDM, and slim. KDM and GDM login manager installations are not covered here, because they are part of base windowmanagers with heavy dependencies.

Without .xinitrc in each home folder, the window manager will fail to load from the console and from the login manager.

The .xinitrc file in the home folder requires a minimum of the following to start from a login manager:

#!/bin/sh
exec $1

It appears that /usr/local/share/xsessions/*.desktop replaces the home folder file .xsession. If using .xsession, it uses the same syntax as .xinitrc, plus it must be made executable.

.desktop files are in xdg-style, demonstrated at Desktop Entry Specification. Example of a minimal /usr/local/share/xsessions/jwm.desktop file:

[Desktop Entry]
Name=JWM
Exec=jwm

If the directory doesn't exist, create it by typing:

% mkdir -p /usr/local/share/xsessions/

To proceed with your choice of login manager...

Slim

Slim is a practical choice for a login manager, unless remote login access is needed. To enable slim, edit the line in /etc/ttys to :

ttyv8   "/usr/local/bin/slim -nodaemon"           xterm   on secure

Slim requires a *.desktop file in a directory that is specified by /usr/local/etc/slim.conf next to the sessiondir option; typically this would be /usr/local/share/xsessions; this is explained in the previous section. Older versions of slim had their window manager configured in the file slim.conf by the sessions option.

Customization

To change the background, look into /usr/local/share/slim/themes/default/ [optionally create a backup file of background.jpg] then copy your choice background image to /usr/local/share/slim/themes/default/background.jpg

% cd /usr/local/share/slim/themes/default
% mv background.jpg background.bk.jpg
% cp [pathname/your file] background.jpg

To create multiple themes, you may create a new directory under themes/ that is similar to the default/ directory, then specify this themes subdirectory from /usr/local/etc/slim.conf. If you do this, be sure each used folder ends off with three files named: slim.theme , background.jpg and panel.png.

Add or edit your themes to slim.conf :

#current theme, use comma separated list to specify a set to randomly choose from
current_theme       default,mytheme

To create themes directories:

% cd /usr/local/share/slim/themes
% cp -R default mytheme

Then edit the mytheme/ files to your liking. For more details of slim configuration, type either:

% man slim

% less /usr/local/etc/slim.conf.sample

XDM

To configure xdm to start up on boot, edit /etc/ttys and change the option on line ttyv8 from off to on:

ttyv8   "/usr/local/bin/xdm -nodaemon"  xterm   on secure

Read about the secure setting in this file.

Then set up identical .xsession and .xinitrc files in each home folder, with the contents and permissions as shown in the above section.

If problems occur, check the file /var/log/xdm.log

% less /var/log/xdm.log

Customization files for XDM are located at /usr/local/lib/X11/xdm. See XFree Local Multi-User HOWTO: Using xdm and FreeBSD Handbook: XDM Configuration Files.

WDM

Here is how to set up Wings Display Manager's (WDM).

To enable WDM, edit line ttyv8 in file /etc/ttys to:

ttyv8   "/usr/local/bin/wdm -nodaemon"  xterm   on secure

It's configuration files are at /usr/local/lib/X11/wdm/.

Make sure the file /usr/local/lib/X11/wdm/wdm-config lists your window manager on the line DisplayManager*wdmWm:. The default window manager for WDM is windowmaker:

DisplayManager*wdmWm:           wmaker:afterstep:blackbox:ctwm:enlightenment:fvwm:fvwm2:fvwm95:olvwm:qvwm:tvtwm:jwm

After rebooting, click the option on WDM's login screen, before logging in.

Console

To start from the console, be sure to add exec [window manager] to the .xinitrc file, without an &. Here is an example of the minimum needed .xinitrc :

#!/bin/sh
exec /usr/local/bin/jwm
exec $1

Once it is set up, type:

% startx

Desktop programs

Use the window manager's configuration files or .xinitrc to start up desktop programs.

Xorg

If an error is made, making it harder to edit files from the command prompt, reboot into single user mode, then remount the drive using the command:

% mount -u /

See Configuring X and the FreeBSD Handbook: Chapter 6. The X Window System for more information.

Enabling hardware

To enable the mouse and keyboard, considering that recent versions of xorg are set to use autodetection by default.

Add the following to /etc/rc.conf :

dbus_enable="YES"

For using devfs, add to /etc/fstab :

devfs      /dev       devfs     rw    0   0  # May not be necessary, since devfs automatically uses /dev
fdescfs    /dev/fd    fdescfs   rw    0   0

Programs may have to be built without the hal option. See the manpages: devd, devfs, devfs.conf, devfs.rules, and fdescfs.

For more advanced topics on hardware configuration, see Hardware Configuration, Audio/Video.

Obsolete configuration reference

This is for those who are familiar with older versions of FreeBSD.

Manually setting the option in xorg.conf to the next line enabled the mouse and keyboard:

Option "AllowEmptyInput" "False"

/etc/rc.conf :

hald_enable="YES" #this option can be replaced with FreeBSD's native program devd, if set in xorg-server.

For a custom xorg configuration file:

% Xorg -configure

After testing this configuration, xorg.conf.new can be copied to /etc/X11/xorg.conf:

% cp /root/xorg.conf.new /etc/X11/xorg.conf
