JOGL on Ubuntu - synchornization problem

OpenGL Development JOGL Development
#1

Hi,

I’m sorry if somebody had a same kind of problem, but I haven’t find any topic about this.
I work in Eclipse on Ubuntu 9.10 and in every JOGL application I wrote, Eclipse returns this message:

do_wait: drmWaitVBlank returned -1, IRQs don’t seem to be working correctly.
Try adjusting the vblank_mode configuration parameter.

All applications works fast, but I think, that if I’ll fix this problem, they will run even faster.

Do you have any ideas? Thank you very much for your help. :slight_smile:

I wonder if this has some problem with your ability to do vertical syncing? Also, the message and IRQs hint that this is a very low-level problem for you and I’d strongly suggest upgrading your Linux distro or graphics drivers to see if that solves the problem. On the other hand, if it “works” I might just deal with it and not worry about making it run even faster.
