[Savage40] Dual Head on T23?

[Philip Mucci]

Hi Albert, Alex, and Tim,

Thanks for the info. I should have checked the list first. I downloaded
the latest Xorg binaries, along with common and savage snaps and things
seem to work alright for most cases. (see below)

BTW, let me say now to Alex and Tim, I really appreciate all your hard
work on this stuff. I have used the DRI features before and they were
great. The binary snapshots are a lifesaver also.

I've attached the relevant sections of my xorg.conf also:

Some comments/probs:

1) glxgears shows a black window on Screen 1. If I drag it to screen 0
(the LCD) all is happy. Wierd! This does not happen without Xinerama! I
have no idea how/why this should affect software rendering.

2) killing/exiting X results in 2 black screens. I have to do fn-f7 to
get the display back on the LCD.

3) tried this with shadow register enabled and got the 'super slow X'
symptom mentioned earlier in the email list.

4) I have no idea what the 'clone' option does. It was put there by
system-config-display.

5) Is there MergedFB support in the current savage driver? (ok, DRI and
Multihead is being greedy I know...)

Section "ServerLayout"
        Identifier     "Multihead layout"
        Screen      0  "Screen0" Below "Screen1"
        Screen      1  "Screen1" 0 0
        InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Keyboard0" "CoreKeyboard"
        Option      "Xinerama" "on"
        Option      "Clone" "off"
EndSection

Section "Device"
        Identifier  "Videocard0"
        Driver      "savage"
        VendorName  "Videocard vendor"
        BoardName   "S3 Savage/IX"
EndSection

Section "Device"
        Identifier  "Videocard1"
        Driver      "savage"
        VendorName  "Videocard Vendor"
        BoardName   "S3 Savage/IX"
        BusID       "PCI:1:0:0"
        Screen      1
EndSection

Thanks again!

Philip

P.S. This is on a fedore-core-3 system patched for AFS and Perfctr.
