En aquesta tercera part de la instal·lació del CentOS l'objectiu és configurar el sistema operatiu seguint les instruccions de Bruker,
Un cop completada aquesta tercera part, l'ordinador hauria d'estar a punt per instal·lar el programari de Bruker: TopSpin, CodeMeter, etc.
Per instal·lar els paquets necessaris pel TopSpin s'ha d'executar la comanda
yum install –enablerepo=bruker bruker-topspin-environperò abans, és preferible fer un simulacre i comprovar que no hi ha conflictes,
yum install –setopt tsflags=test –enablerepo=bruker bruker-topspin-environEl simulacre mostra que es descarregaran 153 paquets (65 MB) que, un cop instal·lats, ocuparan 207 MB; que tots corresponen a programes de 32-bits (arquitectura i686), i que no s'ha detectat cap conflicte, de forma que podem executar la comanda,
# yum install --enablerepo=bruker bruker-topspin-environ

Hi ha un paquet que aparentment podria servir per configurar una estació HP Z400 però que finalment decideixo no instal·lar. El paquet és,
però després de llegir la descripció
prefereixo descarregar-lo i comprovar el contingut abans de decidir si cal instal·lar-ho. La conclusió és que no és necessari pel funcionament de l'espectròmetre i que no val la pena instal·lar-ho.
A l'inici del procés d'instal·lació de CentOS 7 es varen instal·lar paquets que Bruker no instal·la i que cal desinstal·lar, per exemple, l'entorn Gnome. Per identificar i eliminar aquests paquets genero un llistat dels paquets instal·lats i el comparo amb el llistat generat a l'ordinador del 500 MHz,
# rpm -qa | sort > avance3-600-pkglist.txt # comm -23 avance3-600-pkglist.txt avance-neo-500-pkglist.txt > list-packages-only-in-600.txt # comm -13 avance3-600-pkglist.txt avance-neo-500-pkglist.txt > list-packages-only-in-500.txt
Llavors genero un llistat que conté els paquets instal·lats només al 600 MHz i afegeixo el seu magatzem d'origen,

i començo a desinstal·lar paquets de Gnome. Primer comprovo si està instal·lat com a “Environment Group”
# yum grouplist [...] Available Environment Groups: Minimal Install [...] GNOME Desktop KDE Plasma Workspaces Development and Creative Workstation Available Groups: Cinnamon Compatibility Libraries [...] System Management TurboGears application framework Xfce Done
i com que no està instal·lat com grup, començo a desinstal·lar les paquets a mà, per exemple,

Al final faig servir les comandes
yum autoremove per eliminar paquets que ja no són necessaris,package-cleanup –leaves per comprovar quins altres paquets es podrien eliminar perquè no els necessita cap altre paquet, i llavorsyum remove `package-cleanup –leaves` per eliminar-los;fins que ja no es troba cap paquet innecessari.
Per ara no elimino cap kernel antic, però caldrà fer-ho en algun moment fent servir la comanda yum remove kernel o preferiblement package-cleanup –oldkernels –count=2,

Connecto a l'estació de treball el monitor ViewSonic VA2445 SERIES (sortida DisplayPort amb adaptador a DVI) i el monitor HP LA1951 (sortida DVI), i l'ordinador els reconeix i configura correctament. El monitor ViewSonic es configura com pantalla principal (finestra del TopSpin) i el monitor HP com pantalla secundària (finestres de la BSMS, de lock, etc.).
Per tal que es faci servir l'entorn KDE en comptes del Gnome, creo un fitxer /etc/sysconfig/desktop on poso DESKTOP=KDE.
# cat desktop DESKTOP=KDE

i a la pantalla del GDM, abans d'entrar, comprovo quin entorn es farà servir i veig que al llistat d'entorns surt el KDE Plasma Environment com a opció seleccionada, i que no surt el Gnome al llistat.
Llavors obro una sessió i comprovo que es carrega el KDE, i que hi ha uns quants processos relacionats amb el KDE,
