Log of X startup
Made a mistake above, should have been Ubuntu 7.10 not 7.04 Could you try adding option ForceSDVODetect true in device section of xorg.conf? Could you upload the X log with ModeDebug on with the working driver for you? Bugzilla didn't work for me yesterday so the discussion continued in private. I'll try to add all the info from that here. The ForceSDVODetect flag is only available in 2.5 driver, I'll need to get that version somehow (just quickly compiling it didn't work, need a newer libdrm as well, so I'll look into it later).

Old log where TMDS is detected properly (although disconnected)

Log from running with 2.5 driver and ForceDVODetect enabled.
I've rerun again with 2.5 drivers and the ForceSDVODetect option. Still no luck with detecting the TMDS.
So your last working driver is 2.1.1? Have you tried other newer drivers? git bisect can help here to find which commit caused this failure. Created attachment 20621 [details] [review] This patch intends to detect sdvo device by (sDVO B/C) data line plese try it thanks Ma Ling I applied the patch and tried it again. It didn't solve the problem immediatly. What seems to be happening now is that it detects two outputs Unknown-1 and Unknown-2 for which it can't find any configuration. I'll send you logs, but I've been busy so sorry you'll have to wait a couple days. (In reply to comment #10) > I applied the patch and tried it again.

Thanks Ma Ling Created attachment 20795 [details] [review] Errik, In order to narrow down the issue, Please try the patch I upload, then paste the log file . reassign, as Ling is looking into this recently. *** Bug 17525 has been marked as a duplicate of this bug. *** ping Erik... try reject due to no response from bug reporter... |

Created attachment 19771 [details] X11 configuration I have a Fujitsu-Siemens Amilo SI-1520. It has an external DVI port to attach an external monitor but when attaching such it isn't detected. I run Ubuntu 8.04 and when I run xrandr the output is as follows: Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1680 x 1950 VGA disconnected (normal left inverted right x axis y axis) LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 261mm x 163mm 1280x800 59.9*+ 60.0 1280x800@60 60.0 1280x768 60.0 1024x768 60.0 800x600 60.3 640x480 59.9 TV disconnected (normal left inverted right x axis y axis) There should have been a TMDS-1 in the above output but it's simply not detected. There is no VGA output on the model. The external display worked properly in Ubuntu 7.04 so perhaps something changed in the intel-driver since then. Attached are my xorg-configuration and the log when starting up X.
