    Description: X.Org X server -- output driver metapackage
     This package depends on the full suite of output drivers for the X.Org X server
     (Xorg).  It does not provide any drivers itself, and may be removed if you wish
     to only have certain drivers installed.


  Following the description advise from above, I tried to install the
particular xserver-xorg-video that matches my hardware, and purge 
xserver-xorg-video-all.  Purging xserver-xorg-video-all tries to 
remove lot of packages.  Because of the following dependency:


    $ aptitude show task-desktop | grep -A1 Depends
    Depends: tasksel, xorg, xserver-xorg-video-all, xserver-xorg-input-all,
             desktop-base, menu


  Is craeting an equivs xserver-xorg-video-all package feasible, and
most simple solution?
