Alien Fluxx under Red Hat 9

OpenGL Development
#1

Hi, ;D

this night i installed Red Hat 9 on my Maschine. Java Runs fine, also Webstart works! I tried to lauch Alien Fluxx also my Render To Texture Demo without
luck. The Render Demo comes up with the Config Dialog, showing me the avaible Display Modes - but with 0 (zero) HZ refresh rate.
Maybe someone could post some hints to get all working. I must say that the Configuration of my Radeon Gfx Card isnt well working, i actuall runing the Generic Vesa Driver. If i launch the Alien Trial nothing happen for me to see - tries it allways to get in Fullscreen Mode ?

0Hz refresh rate is normal under Linux - it means that we can’t choose or alter it from LWJGL.

You need to make sure that OpenGL on your system is using hardware acceleration, which involves mucking around with some configs or other. It works fine on my Nvidia RH9 installation.

AF always runs fullscreen.

Ok,

will try to get it working later this day. What about the Render Demo, if i try to run in Windowed Mode it also
seems to crash. I thought the MESA lib will do Software Rendering if no Hardwarce Accl. avaible ?

Ok,

i found the hs_err_pid files for the Render To Texture Demo, for me it seems not to be a problem with the Mode switch :-/, there the output:

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x0
Function=[Unknown.]
Library=(N/A)

NOTE: We are unable to locate the function name symbol for the error
just occurred. Please refer to release documentation for possible
reason and solutions.

If it’s crashing in glGetString which is a GL1.0 function it’s safe to say something’s broken and it ain’t our fault :smiley:

Tried the debug library? (Use -ea on the commandline)

Sorry,

haven’t found time to test it. :frowning:
i was working on new version of my player.
Will try it with debug lib asap.

It could still be our fault, if the function pointers is not yet loaded. Have you created the Window before you call GLCaps.determin…?

First some recovery of all Code must be done.
