That's true.

The device has a DVI *and* VGA output and while using DVI output (without adapter of any kind) we're getting a blank output. VGA output to VGA display works fine - this is what we use currently as a work-around.

This is another issue however and is probably related to the topic you mentioned above and is not related to this bug.

I fully agree with you and I also want to see this fixed and present in Ubuntu. Unfortunately the rules (btw. those are Ubuntu rules rather than Canonical) are very strict and I don't think they can be bypassed in any way other that those described at the wiki pages (SRU and MRE).

However, I would still like to provide any help necessary in making sure the new releases will be included in upcoming Ubuntu releases. Would you mind if we continue the discussion on the openchrome-devel mailing list?

Thank you,
