XFree86 4.1.0 & Framebuffer

[Giorgio T. <de...@ip...>]

Hi,

i wish to submit some problems i have found with
X and framebuffer:

1) It works stable with GLINT and FBDev but when
   I try to change Virtual Terminal it trashes the
   terminals and hangs the machine. Is near to be
   impossible to exchange VTs as with old X 3.3.6.

2) When i want to shutdown the machine the only
   way i have, when I am using X, is:
   a) To close the X session restarting (X,G,K)DM
      session (and in this nothing wrong).
   b) With a external terminal ( I use ttyS2 connected
      to another computer) become superuser and
      kill -KILL the xdm & xfree processes and shutdown
      from this terminal.

Note that if I try to use the -TERM signal with XFree
it hangs the machine and with the above kill procedure
the main screen remains trashed so if I wish to work
on other things i must use ttyS2.

3) Sometimes when scrolled, the text becomes warbled
   also with 1024x768 but not as 1152x864.
   Is this a limitation of Accelerated driver ?  

I attach my XF86Config-4 file if some corrections are
needed.

Many thanks
