I plugged the boot SSD configured for Radeon's into a 466 MHz = PowerMac3,4 that has a Radeon card (a single processor G4 model, unlike = all prior tests) and did not change the xorg.conf compared to there = other 2 Radeon PowerMac tests done with that SSD. Xorg with xfce4 worked fine! So as near as I can tell 10.0-STABLE powerpc r268571 (July-13) for Xorg = with xfce4 from around 9 days later has Xorg-with-xfce4 problems for = dual-procesor G4's only. Single processor G4's and Dual processor G5's and two dual-core = processors contexts all work fine. The problem is not specific to Radeon = or to NVIDIA cards. =3D=3D=3D Mark Millard markmi@dsl-only.net On Aug 31, 2014, at 3:35 AM, Mark Millard <markmi@dsl-only.net> wrote: I should have mentioned the following: These SSD's are as they were when I originally reported the original = issues on July-23: the ports used match that time frame.
