With xorg intel driver, is it possible to bypass DDC and use a higher resolution?
Hi, I just bought a machine with Intel DG45ID mother board. I installed openSUSE 11.1 and use the on-board graphics card to connect my 37' Full HD LCD TV via a HDMI cable. However the highest resolution can be used is 1600x1200 instead of the real physical resolution 1920x1080. According to xorg's log file, the supported resolutions reported by my TV are: (II) intel(0): EDID vendor PRI, prod id 5632 (II) intel(0): Using hsync ranges from config file (II) intel(0): Using vrefresh ranges from config file (II) intel(0): Printing DDC gathered Modelines: (II) intel(0): Modeline 800x600x0.0 40.00 800 840 968 1056 600 601 605 628 +hsync +vsync (37.9 kHz) (II) intel(0): Modeline 800x600x0.0 40.00 800 840 968 1056 600 601 605 628 +hsync +vsync (37.9 kHz) (II) intel(0): Modeline 800x600x0.0 36.00 800 824 896 1024 600 601 603 625 +hsync +vsync (35.2 kHz) (II) intel(0): Modeline 640x480x0.0 31.50 640 656 720 840 480 481 484 500 -hsync -vsync (37.5 kHz) (II) intel(0): Modeline 640x480x0.0 31.50 640 664 704 832 480 489 491 520 -hsync -vsync (37.9 kHz) (II) intel(0): Modeline 640x480x0.0 30.24 640 704 768 864 480 483 486 525 -hsync -vsync (35.0 kHz) (II) intel(0): Modeline 640x480x0.0 25.20 640 656 752 800 480 490 492 525 -hsync -vsync (31.5 kHz) (II) intel(0): Modeline 720x400x0.0 28.32 720 738 846 900 400 412 414 449 -hsync +vsync (31.5 kHz) (II) intel(0): Modeline 1280x1024x0.0 135.00 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync (80.0 kHz) (II) intel(0): Modeline 1024x768x0.0 78.80 1024 1040 1136 1312 768 769 772 800 +hsync +vsync (60.1 kHz) (II) intel(0): Modeline 1024x768x0.0 75.00 1024 1048 1184 1328 768 771 777 806 -hsync -vsync (56.5 kHz) (II) intel(0): Modeline 1024x768x0.0 65.00 1024 1048 1184 1344 768 771 777 806 -hsync -vsync (48.4 kHz) (II) intel(0): Modeline 832x624x0.0 57.28 832 864 928 1152 624 625 628 667 -hsync -vsync (49.7 kHz) (II) intel(0): Modeline 800x600x0.0 49.50 800 816 896 1056 600 601 604 625 +hsync +vsync (46.9 kHz) (II) intel(0): Modeline 800x600x0.0 50.00 800 856 976 1040 600 637 643 666 +hsync +vsync (48.1 kHz) (II) intel(0): Modeline 640x480x75.0 30.72 640 664 728 816 480 481 484 502 -hsync +vsync (37.7 kHz) (II) intel(0): Modeline 800x600x72.0 46.87 800 840 920 1040 600 601 604 626 -hsync +vsync (45.1 kHz) (II) intel(0): Modeline 800x600x75.0 48.91 800 840 920 1040 600 601 604 627 -hsync +vsync (47.0 kHz) (II) intel(0): Modeline 1024x768x70.0 76.16 1024 1080 1192 1360 768 769 772 800 -hsync +vsync (56.0 kHz) (II) intel(0): Modeline 1280x720x60.0 74.48 1280 1336 1472 1664 720 721 724 746 -hsync +vsync (44.8 kHz) (II) intel(0): Modeline 1280x1024x75.0 138.54 1280 1368 1504 1728 1024 1025 1028 1069 -hsync +vsync (80.2 kHz) (II) intel(0): Modeline 1600x1200x60.0 160.96 1600 1704 1880 2160 1200 1201 1204 1242 -hsync +vsync (74.5 kHz) There is no 1920x1080. It's obviously the reason. Then I searched on google and found this article: http://en.gentoo-wiki.com/wiki/Intel_GMA. But the instruction described in this article has no effect. Then I tried to disable DDC by adding Option DDC off or NoDDC, but xorg stopped to work with following error message: (**) intel(0): Option NoDDC (II) intel(0): Output VGA disconnected (II) intel(0): Output HDMI-1 disconnected (II) intel(0): Output HDMI-2 disconnected (WW) intel(0): No outputs definitely connected, trying again...

I tried my TV with my Macbook Pro via a DVI-HDMI cable, resolution 1920x1080 is supported. So the question is, how can I bypass the information reported by DDC and let intel driver use specified resolution forcely?
