Upgrade to 8.58.2 and openGL problems

[PeterO]

I've just upgraded an X86_64 box from Fedora 8 to 10.
fglrx is now 8.58.2

I have an openGL application that used to work fine but now has two problems. I'm using gtkglext-1.2.0

1) Double buffering no longer seems to work.

Despite using
glconfig = gdk_gl_config_new_by_mode(GDK_GL_MODE_RGB | GDK_GL_MODE_DEPTH
| GDK_GL_MODE_DOUBLE);

a call to gdk_gl_drawable_is_double_buffered() returns FLASE.

I use "unique colour" picking, and without double buffering the scene drawn for picking is appearing on the display!

2) I can only open one openGL application at a time, the second one hangs without opening it's window and using 100% CPU.

Any help appreciated.

Bad form to reply to my own post....

But....

I noticed the files section in my xorg.conf was empty, now I've filled it in the problems seem to have gone away !

Section "Files"
ModulePath "/usr/lib64/xorg/modules/extensions/fglrx"
ModulePath "/usr/lib64/xorg/modules"
EndSection
