X on fedora-arm

Im trying to get Xserver running on fedora-arm for some time to test GUI applications that i compile for arm . I didn't have that much experience with yum. I have used fedora-5 for 6 monthsand then shifted to ubuntu. I tried "yum groupinstall "X Window System"", but it didn't work as it supposed to so i have to manually select the xorg packages i have to install to get X windows running. Here is the list of packages i installed
xorg-x11-xauth
xorg-x11-apps
xorg-x11-xinit
xorg-x11-utils
xorg-x11-server-utils
xorg-x11-drv-fbdev
xorg-x11-drv-vga
xorg-x11-drv-cirrus
xorg-x11-fonts-misc
xorg-x11-fonts-75dpi
xorg-x11-server-Xvfb
xorg-x11-twm
I don't exactly know what to install and what not from above; Im just making trail and error. twm is the minimistinc window-manager. u can also install fluxbox. Remember if u issue startx it will start twm, if u want to start fluxbox instead of twm edit the xinitrc file.
