Brief history of SAPO system

SAPO is a set of powerful applications oriented to the CARTA 's implementation (transform artistic creation to technical drawing), designs blond curtains, lace , etc. ... These products are manufactured by the German company Karl Mayer 's textile machinery or in ancient looms leavers.
The SAPO system was originally created for HP's workstations with HP-UX operating system, because they were more powerful than any PC on the market. The personal computing progress make PC getting faster and cheaper, and became more interesting to migrate the code to the new and primitive Linux running on personal computers.

We choose Redhat distribution because was free and had a lot of similarities with directories and config files structure with HP-UX. Redhat became a commercial product, so we move to another open source alternative to maintain and improve the stability and security. This distribution is CentOS, which did not have the latest versions of software that other distributions derived from Redhat have like Fedora, but instead have a better stability .

We kept the maximum appearance with the idea to ​​avoid user adaptation to different environments that haven't used. For this reason, we install a linux compatible HP-UX workstations desktop called CDE, but now we are working to migrate SAPO system to any modern desktops integrated with current Linux versions like Gnome, or KDE, to improve the user experience and comfort as much as possible without losing security and stability.

SAPO system installation's notes

• Currently is needed to install SAPO on PCs, laptops and desktops, where you can install a CentOS Linux operating system. The recommended version up to date is CentOS 5.x, because the old CDE desktop is incompatible with the latest version (CentOS 6 when writing this manual).
• During the operating system installation, hard drive's data could be erased so you should have a backup of your existing user data.
• The setup editor used in this manual is vi. This file editor is very powerful, but not recommended if you don't have previous experience. In this case, there are other editors more intuitive like nano'.
• Remember that edit config files is critical and extremely delicate operation that can make the system won't boot properly.
• A new system installation have 4 stages:

1. Installing the Linux operating system 'CentOS 5.x'.
2. Installing the CDE desktop.
3. Installing the SAPO design system.
4. Installing additional applications.

Rcs	ident	ID software version.
LibXpm	Graphic's Library for XPM Pixmap formats	needed by Applications Manager package
Kernel-devel	Code Source operating system	The kernel-devel version must fit with the kernel version installed in the system. The PAE kernel should be installed in PC with more than 4Gb of RAM. Is necessary for compilation of hardware controllers like (license key, graphics card drivers ...)
Kernel-PAE-devel
Gcc	GNU Compiler

To know the installed kernel version use the command uname-r When uses the wildcard character '*' the shell will use the files that match with parameters. In case you wish to use '*', it is possible that the arguments send to yum were wrong. An alternative is not use the asterisk or use a empty temporary directory and run the order inside. If the kernel version is "PAE", use yum install kernel-PAE-devel in place of yum install kernel-devel

[Root@centos5 INSTALACION] # cd yuminstall [enter]

[Root@centos5 yuminstall] # yum install xorg-* [enter]

[Root@centos5 yuminstall] # yum install compat-libstdc + + -33 [enter]

Xorg server configuration and driver setup

1. If needed login as root.

CentOS release 5.8 (Final) kernel 2.6.18-308.4.1.el5 on an i686 CentOS5 login: root [enter] Password: ****** [enter]

2. Change to the directory /home/CADT/INSTALACIO.

[Root@CentOS5 ~] # cd /home/CADT/INSTALACIO [enter]

The following commands assume that are executed from /home/ CADT/INSTALACIOfolder If the computer doesn't have a NVIDIA Quadro 4 or NVIDIA Quadro FX, with default CentOS system drivers, might work, but still, it is recommended whenever possible to install the official of the graphics card.

3. Check the graphics card model.

[Root@CentOS5 INSTALACIO] # lspci | grep VGA | more [enter]

4. Install by model and manufacturer

Graphics	Installation Method
Nvidia	Official NVIDIA drivers using an interactive wizard to install. [Root@CentOS5 INSTALACIO] # sh ./NVIDIA-Linux-x86-290.10.run When the process finishes, the wizard will ask for confirmation to update the configuration file Xorg (/etc/X11/xorg.conf). It is recommended to accept the option to update the configuration file according to the new driver installed.
ATI	Download and follow the instructions at [1] official website of ATI / AMD or install from "elrepo" repository downloading kmod-fglrx93 either kmod-fglrx (depending on your graphic card. see: http://elrepo.org/tiki/kmod-fglrx) yum install kmod-fglrx93 aticonfig --initial You should know that any graphic card using the kmod-fglrx93 will not work on CentOS 6 because the Xorg version, so you will have to use the default drivers.
Intel	Download and follow the instructions page unofficial drivers intel Intel sends you to this unofficial site.



5. Xorg config file modifications
1. Backup xorg.conf file.

xorg.conf is a critical file and therefore we recommend a backup before editing it

[Root@CentOS5 INSTALACIO] # cp /etc/X11/xorg.conf/ etc/X11/xorg.conf_old [enter]

2. Edit the configuration file ' 'Xorg.

[Root@CentOS5 INSTALACIO] # vi /etc/X11/xorg.conf [enter]

The configuration file /etc/X11/xorg.conf should be in a manner similar to this example:

The values ​​should meet with your computer's hardware specifications.. The 'SendCoreEvent' value, defines whether the stylus will work on the desktop. In CentOS 6, it will be necessary to create the xorg.conf file with: Xorg -configure That file will be saved at ~/ so you should move it to /etc/X11: mv ~/xorg.conf.new /etc/X11/xorg.conf

Desktop

Installing CDE desktop

1. Change to directory /home/CADT/INSTALACIO .

[Root@CentOS5 CADT] # cd/home/CADT/INSTALACIO [enter]

The following commands assume that user has administrator privileges and are run from /home/CADT/INSTALACIO.

2. Mount Dextop_CDE_v3.iso file.

[Root@CentOS5 INSTALACIO] # mount-o loop mnt Dextop_CDE_v3.iso [enter]

-o loop option allows us to mount a cdrom or dvd image from iso format.

3. start the installation.

[Root@CentOS5 INSTALACIO] # cd mnt [enter] [Root@CentOS5 mnt] #./Install [enter]

CDE uses an interactive wizard to install.

OPTIONS TO CONSIDER: Full installation do not instal lxinitrc Enable login CDE at startup (dtlogin)

Still dl not reboot the computer despite wizard recommendation, because the install process and updates hasn't yet completed.



4. When installation finish release mnt folder.

[Root@CentOS5 mnt] # cd .. [Enter] [Root@CentOS5 INSTALACIO] # umount mnt [enter]

---

CDE patches install

1. Mount DeXtop_3.2_patches.iso file'.

[Root@CentOS5 INSTALACIO] # mount -o loop mnt DeXtop_3.2_patches.iso [enter]

2. To start the patches installation.

[Root@CentOS5 INSTALACIO] # cd mnt [enter] [Root@CentOS5 mnt] # ./Install [enter]

3. CDE patches install
Installation is automatic and no requires user intervention. When finished, release the mnt folder.

[Root @ CentOS5 mnt] # cd .. [enter] [Root @ CentOS5 INSTALACIO] # umount mnt [enter]

NO reboot the computer, is still necessary to modify some configuration files.

---

Post-install of CDE desktop

1. Modify the default run level in the file /etc/inittab.
1. Edit the file /etc/inittab

[Root@Centos5 CADT] # vi /etc/inittab [enter]

2. Replace

Id: 5: initdefault:

with

Id: 3: initdefault:

3. Save and exit


2. Encoding setup.

CDE desktop is not compatible with the UTF-8 encodings. </ li>

1. Edit File /etc/sysconfig/i18n

[Root@centos5 cadt] # vi /etc/sysconfig/i18n [enter]

2. Replace the line

LANG = "xxxx.UTF-8"

by

LANG = "xxxx"

3. Save and exit


3. Change to the directory /etc/dt/config.

[Root@CentOS5 INSTALACIO] # cd /etc/dt/config [enter]

The following commands assume that are executed from /etc/dt/config.

The CDE desktop create a directory extructure in /etc/dt, this is a mirror of /usr/dt where are the default settings.
Before editing any configuration file of CDE, this must be copied into the appropriate directory in /etc/dt and then modify it there.


4. Copy the file /usr/dt/config/Xservers in the configuration directory /etc/dt/config.

[Root@CentOS5 config] # cp /usr/dt/config/Xservers. [enter]

5. Modify the file Xservers to indicate where theX server is in the current installation of Xorg.

X Server programs (Xorg) have changed their location on the different CentOS versions of the Linux operating system.

Xservers is a critical file and make a mistake during the modification may cause the system doesn't boot properly. It is recommended to backup it.

1. Backup

Root@CentOS5 config] # cp Xservers Xservers_old [enter]

2. Edit Xservers

[Root@CentOS5 config] # vi Xservers [enter]

3. Change line

: 0 Local local_uid @ tt1 root/usr/X11R6/bin/X: 0

by

: 0 Local local_uid @ tt1 root/usr/bin/ X: 0

4. Save and exit


6. Correct the CDE directory where will find the local X server's files.

CDE desktop install a own X server structure, this structure is incompatible with current Xorg, so you have to setup where is the actual X server location in the system.

This change makes that a reinstall of CDE desktop would overwrite the original files for the Xorg server so it is advisable to undo this operation prior to any reinstall of the desktop.

1. Change to the folder /usr/X11R6/lib

[Root@CentOS5 config]# cd /usr/X11R6/lib [enter]

The following commands assume that user is in the folder /usr/X11R6/lib.

Rename the folder
2. X11 to X11.cde

[Root@CentOS5 lib] # mv X11 X11.cde [enter]

3. Create a symbolic link to the directory where is X system original CentOS

[Root@CentOS5 lib] # ln-s / usr/share/X11. [enter]

7. Turn on the typeface service for X ( xfs)

in the installer. Lar desktop corrections 'CDE', service xfs is disabled.

[Root @ CentOS5 lib] # / sbin / chkconfig xfs where [enter]

8. Restart to verify that all configuration is correct

 [root @ CentOS5 lib] # reboot [enter]
