I used to run the following as a blatant waste of otherwise useful resources. Mostly because I can and my M$ addicted friends can't. I have not been able to, since I upgraded to FC3 from FC2. When I run the command: /usr/X11R6/lib/xscreensaver/atlantis -root & I get: X error in atlantis: X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 3 (X_GetWindowAttributes) Resource id in failed request: 0xe Serial number of failed request: 21 Current serial number in output stream: 22 The same is true for Gallaxy which I would also run this way from time to time. /usr/X11R6/lib/xscreensaver/gallaxy -root & X error in galaxy: X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 3 (X_GetWindowAttributes) Resource id in failed request: 0xe Serial number of failed request: 21 Current serial number in output stream: 22 Any ideas? Thanks. - Beyond that, for what it's worth (for those who care) I "nice" the thing to about nothing and with my nvidia graphics card, the 3D stuff really doesn't tax my machine at all.
