Strange X11 error messages when running through ssh

Post by admin »

[Moved from FAQ page]

I'm using Geopsy or other graphical tools on a remote server through a ssh connection. I often get strange X11 error messages like:

Code: Select all

X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  10 (X_UnmapWindow)
  Resource id in failed request:  0x139
  Serial number of failed request:  33338
  Current serial number in output stream:  33588
X Error: BadWindow (invalid Window parameter) 3
  Major opcode: 7 (X_ReparentWindow)
  Resource id:  0x3a

To avoid these messages and to get a nicer graphical user interface, you must disable the X11 security extension controls on your local X11 server. This is possible with option '-Y' rather than simply '-X' (see ssh man page for details). You can enable this behaviour by default if you add the 'ForwardX11Trusted yes' to your /etc/ssh/ssh_config (see ssh_config man page for details). More information can be obtained from

Kindly suggested by Pierre Gouedard (LGIT).
