OK, after upgrading the ati driver seems to work well with the card (which definitely was not the case the days before I've opened the bug, because the ati driver is where I started to solve problems.
However, the ati driver does not seem to support the HDMI audio. An HDMI audio device appears, but does not work. The radeon and radeonhd drivers did not work either with audio, but at least I found hints in forums that the latest radeonhd driver from ATI's web site was what is needed to get HDMI sound working. regards -- Bad support for ATI RS690 / X1200 graphics card https://bugs.launchpad.net/bugs/367409 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
