I have both SL58 and SL62 -- Both yum updated/upgraded without issue :P Sorry - I meant to say that this was a 6.1 version machine which seems to be the crux of the problem for me at least. The updated gnome-screensaver got installed last night along with the xorg-x11-server-Xorg I had downgraded yesterday. However restarting X still failed - the logs suggested it was the ATI driver at fault, so I installed xorg-x11-drv-ati-6.14.2-7.el6.x86_64.rpm from a 6.2 repository and now it all works once more. -- Mark Whidby Infrastructure Coordinator (Unix) Physics/Chemistry/EAES/Mathematics Team IT Services, Faculty of Engineering and Physical Sciences
