X11 error debuging

[kszewczyk]

Hello everyone,

I have trouble with debugging X11 Server Errors for example:

X Error: BadMatch (invalid parameter attributes) 8
  Major opcode: 2 (X_ChangeWindowAttributes)
  Resource id:  0x480000a

I would like to have some more details on cause of this error, from that message I know that its something wrong with filling XSetWindowAttribs structure, but i dont know what field its wrong?

Best Regards
kszewczyk
