Hi all, I have a PowerBook G3 400 Firewire running testing, and I recently installed these packages on my system during an update: x-window-system-core xlibmesa-gl-dev xlibmesa-glu-dev xlibmesa3 Anyway, after the install, I rebooted, then tried to play a game or two that uses GL. I get a garbled screen now that looks like the refresh rate is off. Can anyone tell me what I can do to fix this? Thanks! -M.
