Fullscreen mode crashes applications

Hello all!
Whenever I try to run a Panda application in fullscreen mode (using fullscreen #t in the Config.prc file) it crashes. I changed the notify-level to spam and this is what i got:

All my other OpenGL applications are working without problems. I’m using Panda 1.0.5 on Gentoo Linux with Python 2.4.1. My graphics card is a Radeon X700. Seems to me like there is some problem with my radeon drivers, but i can’t figure out what’s going wrong.
Any suggestions are welcome :slight_smile:

Actually, fullscreen mode is not supported on Linux–unfortunately, the standard glx API for OpenGL via X does not define a way to switch the monitor into fullscreen mode.

Of course, Panda shouldn’t have crashed when you requested fullscreen mode; it should have ignored the request. I’ll fix that bug.


Oh, that’s good to know. Maybe there will be a workaround in the future.
Thanks for your reply!
