I also observed this with 10.10 AMD64 server version. With updates current as of January 10, 2011. In my case, I was using an Asus M2A-VM motherboard with AMD690G and SB600 chipset. This is a Radeon X1200 video equivalent.
I got around the problem by replacing the motherboard with one with a 785G north bridge. So the problem looks to probably be unique to the 690G in my original setup here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/539851 Title: [drm:radeon_dvi_detect] *ERROR* HDMI Type A-1: probed a monitor but no|invalid EDID -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
