Below is a chart abstracted from Alex's earlier emails which I hope
makes the relevant variables easier to compare; Alex, please correct
me if I've gotten anything wrong. The basic observations at this
point are:
- 8.2.19 patches do not seem to fix any of the three problems
- ffb machines test ok
- some afb machines test ok
hostname graphics rel java3d vtkit
----------------------------------------------------------------------
m37-312-21 afb 8.2.17 ok ok
allegretto afb 8.2.19 crashes X distortion
mushu afb 8.2.17 crashes X distortion
whirlwind m64, 2M 8.2.19 ok XGLNOPEX
m56-114-1 m64, 4M 8.2.17 ok XGLNOPEX
problem legend
--------------
crashes X self-explanatory?
distortion graphics are drawn outside of the demo window, broken
up over the screen
XGLNOPEX demo doesn't work at all unless env var XGLNOPEX is set;
extremely slow when it is set
--Abby
P.S. Bill: I verified that mushu is indeed afb, not ffb, and also that
allegretto behaves in the same way Alex described on a clean test
account. The page I mentioned on Sun's doc. site says:
---------------------------------------------------------------------
Some 3D applications may experience problems when run on the PGX
frame buffer. Problems may range from incorrect rendering to window
system crashes.
The work-around for these problems is to set the environment variable
XGLNOPEX before executing any 3D applications. For example:
setenv XGLNOPEX
You do not have to assign any particular value to this environment
variable, just create it.
