HTH > Focus ist not problems with fglrx. I know most of them very well and using it only due lack of alternatives (yuv, xvideo will come soon for new cards hopefully). This is not a random crash or freeze, nor is 3d composite active. It just crashs 100% reproducable when clicking on Display. I guess your answer means, that you are not able to reproduce it, so it doesn't seems to be a package linkage error? I will then report it as a bug upstream, cause whatever happens it should not close "systemsettings". However, there is not even krash is appearing, so there is no traceback or something. The "fglrx" was just a blind shoot, because I know that it is causing lots of troubles. So if a nvidia user or "radeon(hd)" saying that he cannot reproduce it, it might be a very important information for the bug report, that currently nothing more than a "crashs is always reproducable".
