Subject: Re: port-macppc/53496: X segfault during startup on clamshell iBook
 G3 with ATI Rage 128 graphics card
Date: Sat, 4 Aug 2018 01:53:10 +0100

 Managed to stop the crashes and get X11 running by disabling DRI
 acceleration & specifying the resolution for each mode manually.
 Unfortunately though X11 is running, graphics start off corrupted and
 the screen fades out. Pressing ctrl-d terminates X11 and the system

Subject: Re: port-macppc/53496: X segfault during startup on clamshell iBook
 G3 with ATI Rage 128 graphics card

 As a workaround, it's possible to run X by disabling r128fb in the
 kernel and using the wsfb driver for X11 though system system is
 restricted to 8bit colour depth.
