R works in KDE but not in Gnome

I have a Red Hat 7.0 system, plus glibc-2.2 and gcc-2.96.69. When I run the
R demo 'demo("graphics") with KDE it runs fine, but when I try it with Gnome
it croaks:

	demo(graphics)
	---- ~~~~~~~~

Type  <Return>	 to start :

opar <- par(ask = interactive() && (.Device %in% c("X11",

"GTK", "windows", "Macintosh")))

x <- rnorm(50)

opar <- c(opar, par(bg = "white"))

plot(x, ann = FALSE, type = "n")

Hit <Return> to see next plot:

abline(h = 0, col = gray(0.9))

lines(x, col = "green4", lty = "dotted")

Error in plot.xy(xy.coords(x, y), type = type, col = col, lty = lty, ...) :
	Error: X11 cannot allocate additional graphics colors.
Consider using X11 with colortype="pseudo.cube" or "gray".

This has happened with every release of R I've tried; the latest is
R-base-1.2.1-2. BTW, if it matters, the display is set to 800x600, 8-bit
color. But it works with KDE.
