Hi,
We've just installed a brand new version of PV-WAVE on our Suse-Linux
box. The applications which used to look really good on an rather old
SGI, now show up in these really psychedelic colors.
I suspect this is related to the visual classes provided by the
XServer, but am very unsure about what really should be done.
Any clues?
