(No other changes are involved.) Earlier when trying the "/dev/mem instead of /dev/console for = memory-mapping frame buffers in X11 on PowerPC" testing I had reported = that I was unable to get to the point of a reasonable test on PowerMac = G4's, including for NVIDIA. = (http://lists.freebsd.org/pipermail/freebsd-ppc/2014-July/007124.html) > PowerMac G4 (3,6), GeForce4 Ti 4600: UI hangs during the initial xfce4 = "welcome" screen update, frequently without the background being = finished. What is displayed seems fine as far as it got. Can still = Option-Fn just fine to get back to VTn and use it. The "PowerMac G4 (3,6), ATI Radeon 9000/PRO If (AGP/PCI)" was far worse = off for as much as I tested back then: random varying garbage displayed = and it ignored my input after attempting to switch back to to a VTn. = Forced power switch based shutdown. Now that I've access to the Power Mac's again I experimented more with = "PowerMac G4 (3,6), ATI Radeon 9000/PRO If (AGP/PCI)" and I managed to = make it work better then what I reported before. Avoiding DRI (use = NoAccel or use "False" for DRI) makes the Radeon behave the similar to = the NVIDIA GeForce4 Ti 4600 as indicated above. The difference is that = the VTn stays black when I switch to it. But it does take what I type = and executes the commands, such as reboot. (Yep: still syscons.) In both G4 contexts the Xorg.0.log that results appears to have no = information indicating any failure. Of course in each case = /etc/X11/xorg.conf was generated (-configure) for the card in use, but = with NoAccel in use. The SSD has: FreeBSD FBSDG4S0 10.0-STABLE FreeBSD 10.0-STABLE #0 r268571: Sun Jul 13 = 05:15:31 UTC 2014 root at = grind.freebsd.org:/usr/obj/powerpc.powerpc/usr/src/sys/GENERIC powerpc BUT... Now switching that SSD to a G5 PowerMac and booting from it: PowerMac G5 = (7,2), Radeon 9800PRO NH (AGP) Using the same Radeon /etc/X11/xorg.conf (with NoAccel enabled or with = "False" for DRI in each context): X11 with xfce4 works fine!=20 Even switching to a VTn works fine on the G5 PowerMac: it is displays = correctly instead of ending up with a black screen. The generated -configure xorg.conf.new is the same for the two Radeon = contexts. But in each case I need to pick an option that disables DRI = use in order to get reasonable behavior. Without NoAccel/"False"-for-DRI for the G5: text does not display = correctly and if composite is enabled with shadows then the shadowing is = messed up. Bit/Byte order/alignment issues when accelerated? The Radeon 9000 with DRI enabled gets a Xorg.0.log report that = r200_dri.so is not found and the Radeon 9800 with DRI enabled gets a = report that r300_dri.so is not found. (As is probably expected in each = case.) So the behaviors are examples of the error handling for "not = found". Mac OS X 10.4 works fine in all the PowerMacs involved: no evidence of = problems. =3D=3D=3D Mark Millard markmi at dsl-only.net
