  thanks a lot. is this documented somewhere?

  <sort-of-rant on which packages to get>
  this problem is more general, there are some 'groups' of packages that
all provide same/similar functionality but it's not clear which ones
work together, netscape packages are similar (or at least were when I
was installing netscape).
  </sort-of-rant>

  I just installed xlibmesa3:

  btw it automatically gets rid of mesag3-glide2, I guess by now I can
remove glide2 as well...

  I jut installed xlibmesa3 and it didn't help, while installing it I
got bunch of following errors:

dpkg: mesag3-glide2: dependency problems, but removing anyway as you
request:
 xbase-clients depends on libgl1; however:
  Package libgl1 is not installed.
  Package mesag3-glide2 which provides libgl1 is to be removed.

  I got these for all the packages (AFAIK, lot of them: xpp, libfltk1,
xscreensaver-gl, vreng, xlockmore-gl, kdebase etc...)

  how do I test it now? I got the following info from glxinfo:

jojda:/etc/X11# glxinfo -display :2
Xlib: connection to ":0.0" refused by server
Xlib: Client is not authorized to connect to Server
display: :2.0  screen:0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:
    GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context
...

  it says direct rendering is suppoerted, how do I test it? I ran
atlantis and it did not complain (it ran in a window), how do I know
whether it uses 3d acceleration (opengl) or not? It runs quite fine on
-depth 24 (where DRI is not supported)... How do I run the opengl
application fullscreen? The old mesa used GLX_MESA_FX=fullscreen but it
does not seem to work anymore...

  btw what do the Xlib messages mean? why would it try to connect to
:0.0 server???

  I have PCI video card - does this mean that PCI cards don't work?

  I noticed that already. that's quite annoying - is this a temporary
limitation?

  I get basically the same messages...
