The DISPLAY environment variable is either not set, or is set to":0.0" causing the system to use "direct rendering". To avoid this, modify the DISPLAY variable to contain your hostname, e.g. on a system called "dennis": C shell users % setenv DISPLAY dennis:0.0 Bash/Korn shell users: % DISPLAY=dennis:0.0 % export DISPLAY N.B. This may cause a slight decrease in performance If you look closely, they're not actually missing; they're just extremely small. This is because your Motif runtime library is version 1.1.4, not 1.2 [or later] that Explorer requires. As a temporary measure (while you're upgrading your Motif library) you can get the buttons more visible by editing "$EXPLORERHOME/lib/X11/app-defaults/Explorer" and changing the lines: map Editor*miniCpBase*miniCpMgrForm*miniCpMaxBtn*shadowThickness: 0 map Editor*miniCpBase*miniCpMgrForm*miniCpMicroBtn*shadowThickness: 0 If you increase these values to 2, you can see where the button widgets are. You could also experiment with changing the widget sizes, which are by default 16x16 pixels. Some graphics adaptors support only 8 bits per pixel, i.e. only 256 colors on screen at a time. This sometimes forces the window manager to switch colormaps as the user moves from window to window. To ensure this happens correctly when using IRIS Explorer the environment variable "CXCOLORMAP" should be set before running IRIS Explorer: C shell users % setenv CXCOLORMAP Bash/Korn shell users:
% CXCOLORMAP= This is caused by a problem either in OpenInventor, (the library upon which the IRIS Explorer graphics are built) or the IBM OpenGL implementation. It will be fixed in a future version of IRIS Explorer. Until this release, use of the light editors should be avoided. |
