Innocent Bystander

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. Smiley

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.

You cannot reply to this message, because it is very, very old.

 

Add your game by posting it in the WIP section,
or publish it in Showcase.
