Created attachment 30268 [details] [review] Xorg,0,log Do any modes other than 1920x1080 work on the DVI port? Also, do you have a card in the pcie x16 slot assuming the board has one? If so, can you remove it? It's an onboard graphics card, and the board has a PCIEx8 interface (in a x16 slot), which is empty. The onboard graphics has only DVI-single-link, not dual! I'tried to add a 1920x1080 mode with reduced blanking, with the cvt program, and I've also tried other modes, I think down to 1440x900, all with the same result, running at the half frequency. I could try some other monitor the next days... BTW, some weeks ago I was still running the xorg server and radeon driver from jaunty, and the DVI-port didn't work at all. It didn't recognise any monitor. That seems to be fixed now. Well, tell me if I should try some patches, or run some diagnostic tool, I'll try that... Can you attach your video bios?

The video bios (kt690/mITX board by kontron)
This is the video bios, exctracted with your instructions.
I hope this is somehow useful...
BTW, do you think it is a bug in the BIOS? I know there are 2 newer
BIOS versions that I could upgrade to, but I am a bit reluctant as
it's a bit of a hassle, with only linux on this machine...
can you try with ati from git master? Specifically commit 66b194a78c470cb3978f310828dd96c3f3e96944. I've tried now, compiled the xf86-video-ati from git (e57b54daf318ff59315a1c9ed21934f288c5c782) which is 2 commits after the one you proposed to me. I see no difference, VGA output works, DVI runs on 30 Hz vertical frequency, monitor switches off after a minute. BTW, I see no difference in the log file regarding PLL dividers etc. Just the same as for VGA, only it does not work :-( Is this still an issue with kms or a newer driver? Hello,
some months ago, I was running Ubuntu 10.04 with xorg-edgers
repository, so I had a quite bleeding edge xorg,
I think in august it was still an issue.
but I'll try DVI again (simply I'm running the machine on VGA
and didn't quite care about the broken DVI anymore.
I'll also try a new driver again. BTW, it is running KMS,
so the mode switching stuff is in the kernel,
so I just have to compile a bleeding-edge kernel.
Anyway, thanks for your message, I'll report back in a few days...
regards,
Oliver

Created attachment 30267 [details] xorg.conf A 1920x1080 LCD monitor on DVI output is driven semingly at half dot clock, monitor displays "33 kHz x 30 Hz" horizontal and vertical frequencies, for a 1920x1080x60Hz mode. The image is somewhat unsteady, and grayscales look dithered, as if it uses less than 8 bits per pixel. After about one minute, monitor switches off. This only happens on the DVI output, the VGA is running fine. Hardware is a Kontron kt690-mITX board, with embedded ATI RS690 graphics. I'm running ubuntu jaunty, with xorg-edgers ppa, which be quite update with respect to the radeon driver xserver-xorg-video-ati 1:6.12.99+git20091009.f4407962-0ubuntu0tormod~jaunty. I've tried to switch modes with xrandr, works fine on VGA, but on DVI the same symptoms persist, even in different resolutions. Always the monitor complains about frequencies out of range, and vertical refresh is about 30 Hz. I'll attach my xorg.conf and the Xorg.0.log. BTW, the board also has a LVDS connector, which is empty, but Xorg wants to drive it at 1280x800, so try to disable that output with an extra monitor section with the line Option "Disable" "true" not sure if that actually works, xrandr reports the LVDS anyway. Turning it on with xrandr gives an CRTC error though. If I set Option "Ignore" "true" for the LVDS, xorg fails completely, saying it does not find any screen! But that is maybe another bug...
