If you don't like Xephyr for some reason, a similar demo is possible with Xvfb. >From the _console_, do: $ Xvfb -screen 0 1024x768x8 -cc "StaticGray" -render -fbdir /tmp & $ export DISPLAY=:0 $ xterm -bg green -fg yellow & Then start X11 as a regular user and look at the shared memory: $ xwud -in /tmp/Xvfb_screen0 It's greyscale. So _Xenocara_ is capable of running in a greyscale visual. Nothing is broken there. Underlying graphics drivers may or may not support particular modes. But the problem is not with Xenocara.
