I installed Catalyst to get my Radeon video card to stop running so hot, and that problem was solved. Went from around 170 F down to something reasonable and is much quieter. However, now I have a new problem...

Every time I start X, I have to start up the Catalyst control center again, and move the "Scaling Options" slider to the left and then to the right again -- it shows a proper 0% overscan value at first but isn't actually doing that until I reset it, it's actually back at its default, somewhere right between 15% and 0%. It then works properly until I exit X, and I have to fix it again the next time I start X...

I remember on Windows, Catalyst did this by default too, although the important difference being that it actually remembered me disabling it. Why is this a default option though? Do that many people really need it? Almost everyone is using LCD monitors these days...
