I have Catalyst 8.6 running with a Radeon HD 4850. Everything seems to be working, but when I boot up my resolution at the desktop reverts back to 800 X 600. So every time I boot I have to set it back to 1680 X 1050. Does anyone know of a way to set that as a default with Catalyst? There is a default button but it appears to be greyed out. If I make any changes in xorg.conf to try and force that resolution it breaks. Thanks.
