The latest (8.11) Fglrx drivers are underscanning with my FullHD TV, but only with 60 and 50Hz. Frequencies 30, 25 and 24 are working as they should.

Now I can use aticonfig --set-dispattrib=tmds2i,positionX:0 ...sizeX:1920 ...positionY:0 ...sizeY=1080 to fix underscan with 60 and 50Hz.

That would be fine (since those settings will be saved to amdpcsdb), but if I have set those attributes and I change frequency to those lower ones my X crashes (or propably Fglrx drivers).

And since current Fglrx drivers also save used mode to amdpcsdb, X crashes on all reboots (until I modify amdpcsdb to 60Hz mode or remove position and size attributes).

My guess is that "Display scaling to HDTV timings/resolutions." is not working correctly if I have set attributes manually and it does not work with 60 and 50Hz modes (at least on my Toshiba TV).

Is there a way to disable automatic scaling or is this issue going to be fixed anytime soon?

I'm using Ubuntu 8.04 (amd64).
