Gfx and user interface

  1. The file /usr/lpp/X11/defaults/xserverrc should contain the line
       EXTENSIONS=" -bs -d 24:mir0 -d 24:lai0 -d 24:mtn0 -d 24:mint0 -d 24:mojl0 -d 24:cor0 -d 24:son0"
    
    to enable backing store and 24bit colours for special graphics cards (here GXT2000P, GXT135P, GXT3000P, GXT550P, GXT4500 and GXT145 respectively), if installed.
    Alternatively, on AIX versions supporting CDE, in /etc/dt/config/Xservers:
       :0   Local local@console /usr/lpp/X11/defaults/xserverrc -T -force :0 -bs -d 24:mir0 -d 24:lai0 -d 24:mtn0 -d 24:mint0 -d 24:mojl0 -d 24:cor0 -d 24:son0
    
    Note that on AIX 3, the desktop has to be started manually with the xinit command.
  2. On AIX 4.1 with PEX/PHIGS / OpenGL installation the file /usr/lpp/X11/bin/dynamic_ext should contain
       pex             /usr/lpp/X11/bin/loadPex
       GLX             /usr/lpp/OpenGL/bin/loadGL
       gpshm           /usr/lpp/graPHIGS/bin/loadgpshm
    
    and the file /usr/lpp/X11/bin/static_ext should contain
       pex             /usr/lpp/X11/bin/loadPex
    
  3. /etc/X0.hosts and /etc/X1.hosts control the X-server access from other hosts. Due to X-server problems when the name server can't resolve the name of machines listed in these files, they should contain only local machines. This doesn't solve the problem completely (because the local name server might be down as well) but at least the more likely case of external network breakdown is excluded.
  4. CDE configuration
    Path definitions in /etc/dt/config/Xsession.d/0010.dtpaths
    Actual icons and datatypes in /u/bio/.dt/appconfig
  5. For machines with graphic cards, adjust screen resolution:
       smitty
    
       Devices - Graphics Displays - Select the Display Type
    
    choose monitor, then
       Select the Display Resolution and Refresh Rate
    
  6. adjust keyboard properties (for machines with keyboards):
       smitty 
    
       - Devices - Graphic Input Devices - Keyboard - Change / Show Characteristics of the Keyboard 
       Keyboard repeat rate                               [30]                     +#
       Keyboard repeat delay                               250                     +
       Alarm volume                                        off                     +
       Clicker volume                                      off                     +
       Extended keyboard identifier                        none                    +
    
    or on the command line:
      chhwkbd -r'30' -d'250' -a'0' -c'0'
