This does not happens with me on a freshly installed RH-8.0 nor in my=20
SuSE-8.1, but happened in another SuSE-8.1 and now in another RH-8.0!

So, please Matt, run ./xdpyinfo and send us the output, particularly the=20
section relating to "visuals":

(this is my own SuSE-8.1 xdpyinfo)

 number of visuals:    4
  default visual id:  0x21 <--------------
  visual:
    visual id:    0x21 <----------------
    class:    TrueColor
    depth:    16 planes
    available colormap entries:    64 per subfield
    red, green, blue masks:    0xf800, 0x7e0, 0x1f
    significant bits in color specification:    8 bits
  visual:
    visual id:    0x22
    class:    DirectColor
    depth:    16 planes

=2E.. other visual follows, please send them all

The other SuSE-8.1 where the xwin driver fails, xdpyinfo says:

default visual id:  0x23 <----------------------
  visual:
    visual id:    0x21
    class:    PseudoColor
    depth:    8 planes
    available colormap entries:    256
    red, green, blue masks:    0x0, 0x0, 0x0
    significant bits in color specification:    8 bits
  visual:
    visual id:    0x22
    class:    PseudoColor
    depth:    12 planes
    available colormap entries:    4096
    red, green, blue masks:    0x0, 0x0, 0x0
    significant bits in color specification:    8 bits
  visual:
    visual id:    0x23 <------------------------
    class:    TrueColor
    depth:    24 planes
    available colormap entries:    256 per subfield
    red, green, blue masks:    0xff, 0xff00, 0xff0000
    significant bits in color specification:    8 bits

So there is some problem with the way you/ssh setups .Xauthority. In my t=
ests=20
in RH-8.0 I also used ssh and the tk driver runs OK:

jcard@jcard:~> ssh -CX clio.fe.up.pt
[jcard@clio c]$ cat /etc/redhat-release=20
Red Hat Linux release 8.0 (Psyche)
[jcard@clio jcard]$ cd plplot-5.2.0/examples/c
[jcard@clio c]$ ./x01c -dev xwin
Plplot library version: 5.2.0
[jcard@clio c]$ ./x01c -dev tk =20
Plplot library version: 5.2.0

Thanks,
Joao
