Hello,
I admit I am no X window/graphics expert, so have little actual
understanding of these options. However, the standard Fedora core 4
'radeon' driver man page talked about locking AGP pages and that this
could cause problems. I just sort of associated that with this option,
and tried changing it from on to off. What the heck it couldn't make
things worse! :-)
I found the lockup problem was with screensavers that prompted me for a
password. The little window asking for the password popped up, but the
machine then locked solid. Any screensaver which did not have the
'prompt for password' bit worked fine, regardless of whether it as a 2d
or 3d open-gl screensaver or not. The problem happened under KDE with
the kdeartwork screensavers ('euphoria' is the one I used), or under
GNOME with the xscreensavers (from the xscreensavers-gl rpm) using the
'fireworks3d' (I think) screensaver.
John.
