[r128] Driver does not support internal CRT of iMac on PPC

[Joakim Larsson]

Ubunti 6.06 Dapper Drake on an 400 MHz grape iMac PPC results in Xserver to use the external VGA screen instead of the internal CRT which turns black. Using Option Display with CRT, FP, Mirror and BIOS values does not affect what output device is used for the Xserver driver while the kernel FB driver uses the Mirror mode by default. The UseFBDev Option has to be set to "false" See bug:

The bug is that the Option Display should have setting for the internal CRT of an iMac, or is this a feature request....?

The driver do support the internal CRT but the xorg.conf used by the livecd does not setup a proper monitor section. I report this as a separate bug/problem for the installer instead. Please close this issue.

Here is the Monitor section needed in order to get X using the internal CRT:

Section "Monitor"
        Identifier "iMacDVMonitor"
        HorizSync 60-60
        VertRefresh 60-75
        Modeline "1024x768" 78.740 1024 1056 1152 1312 768 769 772 800 +HSync +VSync
EndSection

I found this info at http://wiki.siftah.com/IMac_xorg.conf put up by John Baxendale who got Gentoo's X.org to work on a similar hardware. Thanks John!
