Linux® From Scratch - Quality of Life (System V Edition) - Version #1bc5

Chapter 10. Common Desktop Environment

CDE-2.5.2

Introduction to CDE

The CDE package contains the Common Desktop Environment, a Motif-based desktop environment commonly associated with commercial UNIX workstations.

[Warning]

Warning

CDE has had quite a few known security vulnerabilities in it, and it is likely that several more unknown ones still exist. You REALLY do not want to expose a CDE system to the public Internet. In fact, there are five known security vulnerabilities in this release of CDE which still have no fixes.

Also, you should think strongly about enabling the dtspcd and rpc.ttdbserver daemons. Unless you know what they do, you almost certainly don't need them, and they will increase your machine's attack surface.

CDE Dependencies

Required

FreeType, ksh-1.0.10, libjpeg-turbo, libtirpc, libutempter-1.2.1, libXp-1.0.4, Linux-PAM, lmdb, Motif-2.3.8, ncompress-5.0, OpenSP, rpcbind, rpcsvc-proto, xbitmaps, Xorg Applications, Xorg Legacy, and Xorg Libraries

Installation of CDE

First, apply a patch with multiple upstream fixes and patches: 

patch -Np2 -i ../cde-2.5.2-upstream-fixes.patch

Then, install CDE by executing the following commands: 

./autogen.sh &&
./configure --prefix=/usr --disable-static &&
make
[Note]

Note

This package may print escape sequences during the build process which will make the terminal stop echoing back characters. In order to work around this, you need to blindly type in reset. After the screen is cleared your terminal will work just fine again.

Now as the root user: 

make install &&
install -v -m644 contrib/desktopentry/cde.desktop /usr/share/xsessions

Configuring CDE

Boot Script

To automatically start dtlogin (CDE's display manager) when the PC is rebooted, install the xdm bootscript from blfs-bootscripts with some modifications by executing the following commands as the root user: 

install -d -m 755 /etc/rc.d/rc{0,1,2,3,4,5,6,S}.d &&
install -d -m 755 /etc/rc.d/init.d &&
install -d -m 755 /etc/sysconfig &&
install -m 754 blfs/init.d/xdm        /etc/rc.d/init.d/ &&
install -m 644 blfs/sysconfig/xdm /etc/sysconfig/xdm &&
echo "DISPLAY_MANAGER=/usr/dt/bin/dtlogin" >> /etc/sysconfig/xdm &&
sed -i "s/DM_OPTIONS=.*/DM_OPTIONS=\"-quiet -daemon\"/g" /etc/sysconfig/xdm &&
if ! grep -q '^dm:5' /etc/inittab; then \
        echo dm:5:respawn:/etc/rc.d/init.d/xdm >> /etc/inittab; \
fi

In order to permanently set the default runlevel to 5, starting the dtlogin greeter screen automatically, you can modify /etc/inittab. As the root user: 

sed /initdefault/s/3/5/ -i /etc/inittab
