--- Comment #7 from Jeremy Huddleston <jerem...@freedesktop.org> --- > I'd file a new one OK. Forked off to bug #91804 then. I was just thinking that getting this configuration to work might just not be supported, but if you want to keep heading down this path, I'm definitely game. In this configuration, 'sudo modprobe nouveau debug=VBIOS=debug' results in: Aug 29 23:19:45 wedge kernel: [ 294.071101] [drm] Initialized drm 1.1.0 20060810 Aug 29 23:19:45 wedge kernel: [ 294.127783] wmi: Mapper loaded Aug 29 23:19:46 wedge kernel: [ 294.190330] checking generic (c0030000 710000) vs hw (c0000000 10000000) Aug 29 23:19:46 wedge kernel: [ 294.190337] fb: conflicting fb hw usage nouveaufb vs EFI VGA - removing generic driver Aug 29 23:19:46 wedge kernel: [ 294.190449] Console: switching to colour dummy device 80x25 Aug 29 23:19:46 wedge kernel: [ 294.191803] nouveau 0000:01:00.0: enabling device (0006 -> 0007) Aug 29 23:19:46 wedge kernel: [ 294.192979] [drm] hdmi device not found 1 0 1 Aug 29 23:19:46 wedge kernel: [ 294.193257] nouveau [ DEVICE][0000:01:00.0] BOOT0 : 0x084700a2 Aug 29 23:19:46 wedge kernel: [ 294.193260] nouveau [ DEVICE][0000:01:00.0] Chipset: G84 (NV84) Aug 29 23:19:46 wedge kernel: [ 294.193262] nouveau [ DEVICE][0000:01:00.0] Family : NV50 Aug 29 23:19:46 wedge kernel: [ 294.196982] nouveau [ VBIOS][0000:01:00.0] checking PRAMIN for image...
