[Mesa3d-users] glXCreateWindow on Ubuntu 8.04

[Andrey T. <tsy...@is...>]

Hello,

I'm new to openGL. I read some documentation about GL and GLX from official
openGL site and try to run example from there
http://www.opengl.org/sdk/docs/man/xhtml/glXIntro.xml.

On Ubuntu 8.04(with libgl1-mesa-glx 7.2-1 installed) it creates and
shows window, but then immediately aborts with error:

failed to create drawable
X Error of failed request:  BadDrawable (invalid Pixmap or Window parameter)
  Major opcode of failed request:  55 (X_CreateGC)
  Resource id in failed request:  0x200004
  Serial number of failed request:  19
  Current serial number in output stream:  21

It seems that this error is result of the following line:

glxWin = glXCreateWindow( dpy, fbConfigs[0], xWin, NULL );

When this line is replaced with simple

glxWin = xWin;

everything  becomes ok(window appears, is filled with yellow, and disappears
after 10 seconds).

I think I'm missing something trivial, but I cannot find out what.
Could someone help me? Or, at least, point to previous discussion of
this problem.

Thanks in advance.
