I have applied your second patch on top of 2.6.35-rc5-git4 + 0001-drm-radeon-kms-fix-shared-ddc-harder.patch After successful boot from the new kernel, these lines in Xorg.0.log corresponds now to the outputs I have on my card: ### for LCD connected to the first DVI port: [ 19.582] (II) RADEON(0): Output DVI-0 connected [ 19.582] (II) RADEON(0): Output DIN disconnected [ 19.582] (II) RADEON(0): Output DVI-1 disconnected [ 19.582] (II) RADEON(0): Using exact sizes for initial modes [ 19.582] (II) RADEON(0): Output DVI-0 using initial mode 1920x1080 ### LCD connected to the other DVI port: [ 18.068] (II) RADEON(0): Output DVI-0 disconnected [ 18.068] (II) RADEON(0): Output DIN disconnected [ 18.068] (II) RADEON(0): Output DVI-1 connected [ 18.068] (II) RADEON(0): Using exact sizes for initial modes [ 18.068] (II) RADEON(0): Output DVI-1 using initial mode 1920x1080 HDMI output isn't listed any more. So that's seems good. Thanks a lot for fixing this. I'm just wondering now what will happen if I connect some HDMI device via DVI > HDMI adaptor. Should it work? Is HDMI still supported on my card after applying the last patch? Unfortunately I don't own any device I could test it on. Do you expect any problems with applying this patch onto 2.6.34.1? If not, I could do it as on that kernel the first DVI port is still shown as HDMI. If the patch works OK on 2.6.34.1, it could be submitted upstream to the stable branch ? >> >> Where I see a real 3D performance drop now is for example Armagetron >> Advanced - a game I use just for testing.

Prior to that I'd need a quick look into some manuals .. -- Regards trapDoor -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
