[wellylug] Google Earth

[Rob Collins]

Jon / Alex, (and any others that may know about getting dri for savage 
S3 vt8375 chipset graphics card working)

Tried all the bits that have gleaned from you guys last couple of days 
with some success.  DRI is at least partially working and this is the 
return I get at Konsole:

admins at Kubuntu:~$ cat /var/log/Xorg.0.log | grep DRI
(II) Loading extension XFree86-DRI
(**) SAVAGE(0): DRI is disabled by default on this chipset as it is 
experimental and unstable.
(II) SAVAGE(0): [drm] Enabling ShadowStatus for DRI.
(**) SAVAGE(0): DRI is enabled
(II) SAVAGE(0): [DRI] installation complete
(II) SAVAGE(0): [junkers]pSAVAGEDRIServer:
(II) SAVAGE(0): [junkers]pSAVAGEDRI:
(II) GLX: Initialized DRI GL provider for screen 0
admins at Kubuntu:~$ glxgears >> -printfps
libGL warning: 3D driver claims to not support visual 0x4c

The gears seem to spin pretty smoothly except occasionally (every 15 
seconds or so) they stall for a fraction of a second (almost unnoticeable).

Google Earth works at lightening speed compared to what I was getting 
under software emulation.  However, when zooming in close enough to the 
planet to just see sommes island and wellington airport runway, the app 
crashes spectacularly (the pc freezes) can't even alt-ctrl-bkspace out 
of KDE or alt-ctrl-del to stop google e.  Is there anything obvious in 
the returned text above that would indicate what's wrong?  My xorg.conf 
follows:

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.

# If you have edited this file but would like it to be automatically updated
