Dirk, Thanks but I have tried that. I have also tried other options
i.e. UseEdidFreqs "false" IgnoreEDID "true" NoDDC "true" none of which work....I assume they are driver dependent, since they appear to be be used differently between drivers. for example radeon uses "NoDDC" & nvidia uses "UseEDID" I also tried Option "useROMData " "False" suggested in one of the posts on this bug thread. but no joy. -- [needs-packaging] no working driver for sis 671/771 video cards https://bugs.launchpad.net/bugs/301958 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
