X server crash

[John E Decker]

Hey All,
  New to Debian...breaking from tradition and market forces.
Just installed Debian on an older machine and configured X during setup.
Computer = pentium pro 200
Video = Trident tgui 9680, svga 640x480,8 bpp
Mouse = generic 2-button serial
I keep getting "fatal server error: cannot open mouse(no such file or 
directory)"
I've checked X11 config file and changed the mouse but still get the 
error.Any suggestions?...Thanks!
